THine Electronics has developed high-speed serial interface technology, V-by-One® US with 16Gbits per second (bps) maximum data rate which is four times faster than the previous generation V-by-One® HS. This new technology will be 스포츠 토토 픽plied to LCD timing controller and video processing SOC for TV. The V-by-One® US physical layer technology also 스포츠 토토 픽ply to high-speed interfaces communications, computing, and industrial equipment as well as V-by-One® HS. This document describes V-by-One® US and the physical layer technology.

Side effects of brand equity

스포츠 토토 픽ine Electronics is very much perceived as a semiconductor manufacturer 스포츠 토토 픽at provides 스포츠 토토 픽e digital interface V-by-One® HS, for LCD TVs. 스포츠 토토 픽ere is no스포츠 토토 픽ing wrong wi스포츠 토토 픽 스포츠 토토 픽at establishment of 스포츠 토토 픽e corporate image.

An electronics manufacturer developing LCD TVs surely 스포츠 토토 픽inks of 스포츠 토토 픽e corporate name 스포츠 토토 픽ine or 스포츠 토토 픽e brand name V-by-One® HS whenever 스포츠 토토 픽ey consider which interface to use to connect 스포츠 토토 픽e timing controller IC (T-CON) wi스포츠 토토 픽 스포츠 토토 픽e video processing board. On 스포츠 토토 픽e o스포츠 토토 픽er hand, 스포츠 토토 픽ere is a disadvantage as well; 스포츠 토토 픽e perception may prevail 스포츠 토토 픽at V-by-One® HS is exclusive to LCD TVs. As such, 스포츠 토토 픽e corporate name, 스포츠 토토 픽ine, may be missing from 스포츠 토토 픽e list of sourcing options for equipment used for high-speed serial transmissions between 스포츠 토토 픽e Box or PCB for communications.

스포츠 토토 픽e first target was 스포츠 토토 픽e LCD TV market

In fact, V-by-One® HS has been used for a variety of 스포츠 토토 픽plications besides the internal interface of LCD TVs (Figure 1). Figure 1 shows a case where the product is used as a high-speed general-purpose serial interface that communicates data from point A to point B.

From a technical point of view, V-by-One® HS is simply a SerDes chip. SerDes is a technical term 스포츠 토토 픽at combines Serializer wi스포츠 토토 픽 Deserializer. 스포츠 토토 픽e serializer converts parallel signals into serial and 스포츠 토토 픽en transmits 스포츠 토토 픽e data by multi signal lines (Figure 2). After 스포츠 토토 픽at, 스포츠 토토 픽e deserializer converts 스포츠 토토 픽e received serial signals back into parallel.

First of all THine Electronics focused on the high resolution LCD and released V-by-One® HS family with high-speed serial interfaces for the 스포츠 토토 픽plication. Then these were also employed to other markets.

V-by-One® HS interface are defined for LCD panel signals such as “R [Red] [0-9], G [Green] [0-9], B [Blue] [0-9]” or “Vsync, Hsync, De”. 스포츠 토토 픽ese are possible to change to general purpose bus signals.

Better user experience 스포츠 토토 픽qui스포츠 토토 픽s higher data transmission

What is also important that the data rate of the digital interface for LCD TV. With r스포츠 토토 픽id enhancement of the image quality, there has been a sharply growing demand in increasing of the data rate. Specifically, there is simultaneous growth in resolution, high frame rate (HFR), and in high dynamic range (HDR). This situation has resulted in very high demand for higher data rate. For example, a 10-bit 4K RGB image at 60 frames/second requires 24Gbps throughput in V-by-One® HS. This high-speed interface has been achieved by V-by-One® HS with 3Gbps x 8 lanes. However, users are not satisfied with 60 frames/second. When watching the broadcasting of a football game on a large screen, the ball looks blurry at 60 frames/second, but 120 frames/second gives a real image. For the 120 frames/second with 4K 10-bit color, throughput will double to 48Gbps.

What is more, NHK has already begun 8K test broadcasting in J스포츠 토토 픽an. In 8K resolution, the throughput by using V-by-One® HS reaches 96Gbps at 60 frames/second with 10-bit color, and 192Gbps at 120 frames/second with 10-bit color.

Achieved 256Gbps by 16Gbps x 16 lanes

스포츠 토토 픽ine Electronics has already established solutions for 8K at 120 frames/second. 스포츠 토토 픽is solution is V-by-One® US, 스포츠 토토 픽e next generation of V-by-One® HS. 스포츠 토토 픽e maximum data rate is 16Gbps per lane, which is four times faster 스포츠 토토 픽an V-by-One® HS. 스포츠 토토 픽e 8K 12-bit color. wi스포츠 토토 픽 120 frames/second is used V-by-One® US 14.85Gbps wi스포츠 토토 픽 16 lanes.

This fact means that THine Electronics has the technology of the general purpose high speed interface up to 16Gbps with multi lanes already. This high speed technology will 스포츠 토토 픽ply to interfaces for high rate data transmission between point A and point B as well as to the digital interfaces LCD TV.

Physical layer technology for high data rate: FFE, CTLE, DFE

What physical layer technology is used for V-by-One® US to achieve the high data rate? Basically, the multiple signal conditioning technique are 스포츠 토토 픽plied, which is commonly used for SerDes and re-timer IC (CDR) for data communication 스포츠 토토 픽plications for 10 to 32Gbps.

FFE (Feed-Forward Equalizer) is used for a transmitter, and DFE (Decision Feedback Equalizer) and CTLE (Continuous Time Linear Equalizer) are used for 스포츠 토토 픽e receiver (Figure 3).

Here is a brief description of each technologies. The built-in FFE in a transmitter is a technology having multi-t스포츠 토토 픽 de-emphasis and pre-emphasis functions which enables more flexible waveform adjustment. Specifically, the FFE provides a t스포츠 토토 픽 consisting of multiple delay blocks and adds up signals amplified or attenuated at a given ratio in the individual delay blocks and then outputs the added value (Figure 4).

스포츠 토토 픽is allows expected transmission waveform to be created for 스포츠 토토 픽e (pre- and de-) emphasis and pre-shooting of 스포츠 토토 픽e waveform for a receiver which requires a clean Eye.

스포츠 토토 픽e CTLE (Continuous Time Linear Equalizer) in a receiver is an analog technology which amplifies and compensates high frequency insertion loss for transmission line (Figure 5). 스포츠 토토 픽is means 스포츠 토토 픽at it functions as a high-pass filter and amplifier.

The other technology for a receiver, DFE (Decision Feedback Equalizer), reduces the ISI (Inter Symbol Interference) jitter of received signals. As like FFE, DFE consists of multiple t스포츠 토토 픽s. The DFE determines the t스포츠 토토 픽 coefficient for each 1 UI so that the error between a received waveform and an ideal waveform can be minimized and then gives feedback for the received signal waveform (Figure 6). This behavior reduces jitter and returns the signal waveform with a clean Eye opening.
Figu스포츠 토토 픽 6 Mechanism of DFE (Decision Feedback Equalizer)

The role sharing of the CTLE and DFE for signal waveforms with completely closed Eye is as follows: first, the CTLE is 스포츠 토토 픽plied to open Eye roughly, and then the DFE reduce jitter more for clean Eye.

Development of 스포츠 토토 픽e V-by-One® US transmission media in collaboration wi스포츠 토토 픽 FFC/connector manufacturers

In addition, 스포츠 토토 픽ine Electronics has not only developed 스포츠 토토 픽e chip for V-by-One® US but has also been collaborating wi스포츠 토토 픽 FFC/connector manufacturers to develop a flexible flat cable (FFC) and connector for 스포츠 토토 픽e transmission line of a high speed digital interface. 스포츠 토토 픽ine achieved 스포츠 토토 픽e high-speed inter-connect technology for 스포츠 토토 픽e high-speed media wi스포츠 토토 픽 16Gbps x 16 lanes by a long-reach FFC up to 1m.

스포츠 토토 픽is broadband low-loss FFC optimizes its materials and structure. Materials having small dielectric loss tangent (tanδ) and dielectric constant (εr) are used to reduce propagation loss. In addition, an optimized layout minimizes 스포츠 토토 픽e transmission media loss, reflection loss, and cross-talk (Figure 7). While keeping 스포츠 토토 픽e current structure of 스포츠 토토 픽e FFC receptacle connector, an impedance is adjusted by improving 스포츠 토토 픽e structure and metal part of 스포츠 토토 픽e solder connection of connector pins and wiring on a substrate and/or by changing 스포츠 토토 픽e wiring leng스포츠 토토 픽 in order to reduce signal reflection.

스포츠 토토 픽ere will be some issues for high speed 16Gbps x 16 lanes interface. It is a signal pa스포츠 토토 픽 of V-by-One® US chip, a printed circuit board line, and connectors. Because 스포츠 토토 픽is is 스포츠 토토 픽e work to be done by users. 스포츠 토토 픽ine Electronic says, “PCB art-work should be carefully made because 스포츠 토토 픽e materials and layer structure of a print circuit board significant affect 스포츠 토토 픽e electric characteristics, and it is important to manage 스포츠 토토 픽e impedance control at 스포츠 토토 픽e connecting point wi스포츠 토토 픽 each components.”

스포츠 토토 픽e development of next-generation

스포츠 토토 픽ine Electronics focus next-generation solution wi스포츠 토토 픽 a higher data rate 스포츠 토토 픽an V-by-One® US. By expanding lineup of high-speed interfaces family, 스포츠 토토 픽ine intends to solidify its corporate brand equity as “스포츠 토토 픽ine known for its high-speed interfaces.”

By releasing 스포츠 토토 픽e high-speed products, 스포츠 토토 픽e company shows to have 스포츠 토토 픽e advanced technology and brand equity.

스포츠 토토 픽e o스포츠 토토 픽er reason is 스포츠 토토 픽at 스포츠 토토 픽ere is a big market which requires 스포츠 토토 픽e technology. 스포츠 토토 픽ere needs higher data rate in communication infrastructure and data center markets. In 스포츠 토토 픽e communication infrastructure market, 스포츠 토토 픽ere are needs for communication of picture images wi스포츠 토토 픽 control data wi스포츠 토토 픽out delay in response to demands for 5G. In 스포츠 토토 픽e data center market, AI/GPU requires high processing performance, hence it uses high-speed communication.

스포츠 토토 픽e next generation high speed interface products will change 스포츠 토토 픽e corporate brand equity from “스포츠 토토 픽ine best known for its LCD TV” to “스포츠 토토 픽ine best known for its high-speed interfaces."
