This is a user guide for Altera's LVDS SERDES Transmitter / Receiver (ALTLVDS_TX and ALTLVDS_RX) Megafunction.
The guide describes the LVDS SERDES transmitter and receiver megafunctions (ALTLVDS_TX and ALTLVDS_RX) that can be configured through the Quartus®II MegaWizard Plug‑In Manager or command‑line interface. It covers the features, supported device families, and the parameter options available for each megafunction.
Detailed sections explain parameter settings such as implementation in logic cells versus dedicated SERDES blocks, internal versus external PLL usage, dynamic phase alignment, and file generation options. The document also includes information on using the Clear Box Generator to create custom megafunction variations.
