8.4.1 Pin Control Mode

When in pin mode (ENSMB = 0), equalization and de-emphasis can be selected via pin for each side independently. When de-emphasis is asserted VOD is automatically adjusted per Table 3. For PCIe applications, the RXDET pins provides automatic and manual control for input termination (50 Ω or >50 kΩ). MODE setting is also pin controllable with pin selections (PCIe Gen-1, PCIe Gen-2, auto detect, and PCIe Gen-3). The receiver electrical idle detect threshold is also adjustable via the SD_TH pin.
