The LatticeECP2(tm) and LatticeECP2M(tm) (“LatticeECP2/M”) FPGA interface reference design, from Lattice Semiconductor Corporation (NASDAQ: LSCC), utilizes a new hardware interface card developed by Lattice to work with existing TI and Lattice evaluation boards. The complete hardware/software package gives designers a working model from which they can quickly create their own custom solutions. LatticeECP2/M FPGAs provide a high-speed glueless interface capable of acquiring 14-bit ADC data at rates up to 120 MSPS from the two to four serial channels found in ADS6000 ADC family devices.
The LatticeECP2/M FPGA reference design supports the Texas Instruments’ ADS6000 family of analog-to-digital converters (ADCs). The combination of the LatticeECP2/M FPGA reference design and TI’s ADS6000 solutions boards provides a quick and cost-effective evaluation platform for receiver solutions targeting advanced communications, imaging, test and measurement, and video applications. The new solution enables customers to reach the market fast with a cost-optimized FPGA and multi-channel ADC solution that combines exceptional speed, performance, size and power.
Systems migrating to higher sample rate/ resolution ADCs often require an FPGA with an interface speed of approximately 800 Mbps to bridge between existing hardware and the newer interface provided by the higher speed ADC. Previously, only more expensive, high-end FPGAs could satisfy this requirement. Now, the LatticeECP2/M FPGA family is able to provide these bridge functions in an optimally sized FPGA at a significantly lower cost. With the LatticeECP2/M FPGA devices, designers can focus on processing the ADC data within the FPGA and routing it to other parts of their system without having to worry about the timing details of high-speed ADC interfaces.
The TI ADC interface card enables the interfacing of the ADS6425EVM evaluation board directly with the LatticeECP2 advanced evaluation board. The reference design uses about 5% of the FPGA logic to transfer the ADC codes on the serial source synchronous bus to its embedded block RAM memory. The interface card, LFE2-H-IC-EV, is available immediately from Lattice for $195.00. The LatticeECP2 Advanced Evaluation board and ADS6425EVM boards are available now from Lattice and TI, respectively.
