Part Number: SN75LVCP600S
Other Parts Discussed in Thread: REG104, DS64BR111
SN75LVCP600S datasheet recommends the part to be used one part used on the device-end daughter card (at Rx pins), and one part used on the host’s Rx pins. But in our application, the host Is not what we can control (Host card doesn’t have any SATA redriver implemented).
We only design a small daughter card, then in this use case, our questions are:
Q1, can we design in two SN75LVCP600S parts on the daughter card, one at Rx pins and one at Tx pins?
Q2, From system point of view, do you see any risk with two re-drivers on the daughter card? Esp., will this architecture have risk triggering any Link-down issue caused by OOB detector as broadly discussed on the website?
Q3, Evaluation board has a Ferrite/Capacitor filter at SN75LVCP600S’ power pin, is there any justification to add a large Ferrite/Capacitor filter? For an example, is it targeted to filter out certain frequency band noise? Note: power supply REG104 is already a low-noise LDO
Q4, Noticed Evaluation board has huge amount of Cout (Over 250uF at REG104 output, plus 160uF more at F/C filter), is this really required? Note: REG104 only recommends a 10uF Cout.
