Hi SI-LIST, We are designing a SATA Gen2 board/interface. In reading the specification it appears that the jitter is specified as clock to data jitter for Gen2. The spec. shows that compliance is verified by connection to a scope that contains the proper CDR PLL so that clock to data jitter can be measured. In simulating my design how am I able to verify that I am close to meeting the specification if I do not have the CDR PLL in my simulation? The SATA device vendors do not provide any details in this regard and neither do the silicon vendors we are using. This is new to us here. Any advise would be greatly appreciated.
