LVDS SERDES IP Core Functional Description

You can configure each LVDS SERDES IP core channel as a receiver or a transmitter for a single differential I/O.

Each LVDS SERDES IP core channel contains a SERDES, a bitslip block, DPA circuitry for all modes, a high-speed clock tree (LVDS clock tree) and forwarded clock signal for soft-CDR mode. Therefore, an n-channel LVDS interface contains n-serdes_dpa blocks.

The I/O PLLs drive the LVDS clock tree, providing clocking signals to the LVDS SERDES IP core channel in the I/O bank.
