Is Serdes Necessary to use PCIe, SATA, SGMII interfaces in T1042 ?

[athershehzad]

Hello,
I am using T1042 processor for my board. I have to use two SATA interfaces, all four PCI express interfaces and two 1G Ethernet Interface. My question is that is there any possibility that I can use them without using SERDES ? If I had to use SERDES, then which channel for which interface and how ?

Thanks in advance.

Regards,

So I can not use four PCIe, two SATA and two Ethernet at a time ?

Possible combination is Three PCIe, two SATA and three Ethernet interface.

Thanks Ufedor,

What I have to do if I want some configuration that is not listed in the Figure 31-1 ?
for example I want 4 PCIe, two SATA and two ethernet interfaces

All supported configurations are shown in the Table.

The SerDes is used for each high-speed serial interface.

> which channel for which interface and how ?

Please refer to the QorIQ T1040 Reference Manual, Chapter 31 SerDes Module, Figure 31-1. Supported SerDes Options.
