1. Overview: This article is created to provide a design example on how to perform a pre-CDR reverse serial loopback using Cyclone IV GX devices. There is no official document to describe in details on performing the pre-CDR reverse serial loopback. Main purpose of this design is to verify the transceiver signals coming from other devices that connected to the Cyclone IV GX device. This design example is to be use with Cyclone IV GX Transceiver Development Kit.
Compile the design and load into Cyclone IV GX Transceiver Development Kit. It is used to help customers confirm the transceiver signals from other devices that connected to Cyclone IV GX transceiver through Transceiver Development kit.
