The redrivers are configured to operate in Pin Mode (MODE pins tied to L0).
- RX_Detect state machine of all redrivers is enabled by leaving RX_DET pin open.
- The redrivers are enabled (PWDN pins tied to GND).
- The board is configured for any PCIe bus width.
- DC Gain of all redrivers is set to 0 dB by leaving the GAIN config pin open for the redrivers.
- EQ level of the RX CTLEs of all redrivers is set to 7 dB at 8 GHz by default.
- If necessary, adjust EQ levels of the downstream and upstream redrivers, or both, by arranging shunts on JMP1, JMP2 for downstream redrivers and JMP11 and JMP14 for the upstream redrivers.
- Plug the EVM into a PCIe x16 server motherboard slot. Ensure the motherboard is powered down before installing the EVM or configured for hot-plug operation.
- Install a compatible PCIe endpoint card into one of the PCIe connectors on the EVM based on configuration of the SEL pin. Note: PCIe-A requires enabling bifurcation on the motherboard.
- Power-up the motherboard.
