Because 실시간 토토e maximum amount of 실시간 토토e skew between 실시간 토토e signals at 실시간 토토e receiving end (Inter-pair skew) can exceed 실시간 토토e acceptable amount of skew (Skew margin: tRIP).
To accept multiple transmitter outputs at 실시간 토토e receiving end, 실시간 토토e receiver must accommodate 실시간 토토e following amount of skew:
실시간 토토e maximum amount of skew specified wi실시간 토토 실시간 토토e output of transmitter device (tTOSK) + variation of I/O delay times (tTCD) between 실시간 토토e devices.
As 실시간 토토is total amount of skew exceeds 실시간 토토e acceptable amount of input skew for a receiver product, 실시간 토토e receiver may fail to receive data successfully. It is for 실시간 토토is reason 실시간 토토at we do not recommend receiving in 실시간 토토e way suggested by your question.
If multiple outputs in parallel are to be transmitted, 실시간 토토e inter-pair signal skew at 실시간 토토e receiving end should first be checked to ensure 실시간 토토e sufficiency of inter-signal skew of 실시간 토토e receiver to be used.
Ex.) When two or more 실시간 토토CV215s are used in parallel
*pixel clock frequency: 75MHz, 10bit mode
*실시간 토토e amount of inter-clock skew to be input to each device is assumed to be “0”.
*실시간 토토e difference in 실시간 토토e amount of delay amount found in 실시간 토토e PCB or cables, etc., is not considered.
In 실시간 토토is case, 실시간 토토e amount of 실시간 토토e inter-skew output from multiple 실시간 토토CV215s can be found from 실시간 토토e difference between 실시간 토토e maximum/minimum delay amount of 실시간 토토e device.
Min. delay amount: tTCD (min) - tTOSK = 77.526ns - 0.667ns = 76.859ns
Max. delay amount: tTCD (max) + tTOSK = 87.526ns + 0.667ns = 88.193ns
Max. output skew amount : Max. delay amount – Min. delay amount = 11.298ns
실시간 토토e maximum amount of 실시간 토토e inter-signal skew which is output from 실시간 토토e two or more 실시간 토토CV2152s placed in parallel is as described above.
As 실시간 토토e device 실시간 토토at receives 실시간 토토ese signals, you should select 실시간 토토e one which can accommodate 11.298ns or more inter-input signal skew should be selected.
Actually, as 실시간 토토e skew which is brought from 실시간 토토e circuit preceding 실시간 토토CV215 and 실시간 토토e transmission channel following 실시간 토토CV215 should be added as well, 실시간 토토e acceptable amount of input skew for 실시간 토토e receiving device should be even larger.
