TI evaluation module for its 14-bit ADCs

Texas Instruments has an evaluation module for its 14-bit analogue-to-digital converters (ADCs) when operating in an interleaved fashion with a Xilinx Virtex-5 FPGA in a high-speed digitiser design.

The ADS5474ADX-EVM incorporates two of TI's ADS5474 ADCs, a Xilinx Virtex-5 FPGA and SP Devices' proprietary time-interleaving technology to deliver an 800MSPS ADC capability.

The SP Devices' software continuously monitors the system and removes ADC gain, clocking and temperature mismatches to reduce the interleaving spurs below the ADC harmonic spurs.

By reducing the interleaving spurs, the software increases spurious free dynamic range (SFDR) from 45.78dBc to 86.44dBc for a 70MHz input signal, said the supplier.
