7:1 serialization in FPGAs at 666 Mbps

Keywords:Spartan-3E  Spartan-3E  Xilinx 

Spartan-3E and Extended Spartan-3A devices are used in a wide range of applications requiring 7:1 serialization at speeds up to 666 Mbps. This application note by Xilinx targets Spartan-3E/3A devices in applications that require 4-bit or 5-bit transmit data bus widths and operate at rates up to 666 Mbps per line with a forwarded clock at 1/7th the bit rate. This type of interface is commonly used in flat panel displays and automotive applications.

These designs are applicable to Spartan-3E/3A data bus and not to the original Spartan-3 device. The design files for this application note target the Spartan-3E family. The Extended Spartan-3A family also supports the same design approach. The maximum data ratefor the Spartan-3A FPGA is 640 Mbps for the -4 speed grade and 700 Mbps for the -5 speed grade.
