JESD204C
Overview
The JESD204C controller IP is a highly optimized and silicon agnostic implementation of the JEDEC JESD204C.1 serial interface standard targeting both ASICs and FPGAs. The IP core supports line speeds up to 32.5 Gbps per lane with 64b 66b encoding and includes full backwards compatibility with JESD204B and its 8b 10b encoding. The IP core enables quick and reliable deployment of both the transmitter (TX) and the receiver (RX) link layer and comes optionally with a tightly integrated transport layer option, that can dynamically be configured to handle any Multiple-Converter Device Alignment, Multiple Lanes (MCDA-ML) requirements.

JESD204 Webinar: “Bridging Analog and Digital worlds at high speed with the JESD204 serial interface”
Bridging Analog and Digital worlds at high speed with the JESD204 serial interface
Piotr Koziuk - Jan 13, 2022. To meet the increased demand for converter speed and resolution, JEDEC proposed the JESD204 standard describing a new efficient serial interface to handle data converters. In 2006, the JESD204 standard offered support for multiple data converters over a single lane with the following standard revisions; A, B, and C successively adding features such as support for multiple lanes, deterministic latency, and error detection and correction while constantly increasing...
