Other Parts Discussed in Thread: 66AK2H14
Hello, I'm using the 66AK2h14 ARM+DSP on my new design and I have decided to use the DS80PCI102 Repeater on the PCIe, SRIO and SGMII lanes. The max lanes distance going over FR4 is about 16 - 25 inches and using 4-mil traces. The rates for the links are SGMII 1.25Gbps, SRIO 3.125Gbps and PCIe 2.5Gbps. The ARM+DSP PCB will be a 6U VPX card that plugs into a VPX 4-SLOT backplane. I going to place the repeater as close as possible to the DSP processor and will do the same on the other VPX board which as a Xilinx FPGA.
I've set the DS80PCI102 the same for each protocol:
Table 2:
Level 7 (FR4 20-inch 4-mil trace)
EQA1/EQB = 1K pull-up
EQA0/EQB0 = Float
Table 3.
Level 12
VOD_SEL = Float
DEMA/DEMAb = 1K pull-up
RXDET floating for Auto-RX Detect
Does this seem like a good configuration for all the protocols?
