AVQ-SP6ADC - Light Version of JESD204A interface IP core on XILINX Spartan-6 LXT and NXP ADCs
Introduction
The IP core is a light version of JESD204a serialized interface between data converters and FPGAs. The core implementation is targeted to a two-lane dual ADC with each lane having a 16-bit resolution and running at 125 MSPS.
The core has been tested with NXP ADC1613D125, a dual channel 16-bit Analog-to-Digital Converter (ADC) optimized for high dynamic performances and low power at sample rates up to 125 MSPS.
Features
- 2-lane serial JESD204A interface with 2.5 Gb/s rate per lane using Spartan-6 LXT GTP transceivers;
- Supports physical and data link layer JESD204A requirements;
- 2 octets per frame clock cycle;
- 9 frames per multi-frame;
- Scrambling, character replacement, multiple devices synchronization are not supported in the light version.
