ADS540x and ADS54T0x Evaluation Module (EVM)
This user's guide describes the operation of the Texas Instruments ADS540x or ADS54T0x evaluation
module (EVM). The EVM provides a platform for evaluating the ADS540x or ADS54T0x, a two-channel,
12-bit ADC operating at sampling rates of up to 800 MSPS with the digital data output on two 12-bit LVDS
parallel busses on a Samtec connector.
This EVM is ideally suited for mating with the TSW1400 or TSW1405 Capture Card for performing a data
capture into a capture buffer, uploading the sample data to a PC, performing a Fast Fourier Transform
(FFT), and reporting on signal-to-noise ratio (SNR), spurious-free dynamic range (SFDR), and other
performance metrics.
