The ADS58H40EVM is a circuit board that allows designers to evaluate the performance of Texas Instruments ADS58H40, a quad-channel, 14-bit telecommunications analog-to-digital converter (ADC) operating at sampling rates of up to 250 MSPS. Designed for low-power consumption and high spurious free dynamic range (SFDR), the ADS58H40 has low-noise performance and outstanding SFDR over a large input-frequency range.
The four ADC channels are separated into two blocks with two ADCs each. Each block can individually be configured into three different operating modes: 11-bit Operating mode, 11-bit SNRBoost3G+ mode, 14-bit High Resolution Burst mode.
This EVM is ideally suited for mating with the TSW1400 Capture Card for performing a data capture into a capture buffer, uploading the sample data to a PC, performing an FFT, and reporting on SNR, SFDR, and other performance metrics.
