Texas Instruments ADC14X250EVM Evaluation Module (EVM)
Texas Instruments ADC14X250EVM Evaluation Module (EVM) is an evaluation board used to evaluate the ADC14X250 analog-to-digital converter (ADC). The ADC14X250 is a single channel 14-bit ADC capable of operating at sampling rates up to 250 Mega Samples Per Second (MSPS) with outputs featuring a standard JESD204B high-speed serial interface. The ADC14X250EVM is designed to work seamlessly with the TSW14J56EVM, TI's JESD204B data capture card, and the High-Speed Data Converter Pro (HSDCPro) software tool for high-speed data converter evaluation.
Features
- Transformer coupled signal input network allowing a single-ended signal source
- LMK04828 system clock generator that generates the FPGA reference clock for the high-speed serial interface
- Default transformer-coupled clock input network to test the ADC performance with a very low-noise clock
- High-speed serial data output over a standard FMC connector
- The device registers programming via a USB connector and FTDI USB-to-SPI bus translator
