Other Parts Discussed in Thread: HD3SS3415, DS125MB203, HD3SS3412
Hi,
We have used DS42MB100 as a 2:1/1:2 Mux/buffer in PCIe Gen1 interface. I am raising this question since this device is not explicitly targeted for PCIe designs. Please let me know if you see any issues here. PCIe interface of both host and end point are CML type. PCIe link training is not happening when the signalling is through DS42MB100. We have tried disabling EQS, EQL and DEL & DES set to 0 dB. Still link training failed.
When we bypassed DS42MB100, PCIe link training is passing successfully.
Is it possible to completely disable buffering action and use the device in just 2:1/1:2 mux? Let us know possible solution
Thanks,
Jijesh
