Description

The MZ523A is a mezzanine module for VadaTech’s MRT523. The AMC/MRT523 combination provides 12-channel ADC 16-bit @ 125 MSPS, and this mezzanine routes analog inputs to the ADC.

The MZ523A is intended primarily for system development/evaluation purposes. It provides no buffering or limiting of the input signals, so the user must ensure inputs are within +/-1 V to avoid damage to the ADCs.

The board implements a differential double balun on each mezzanine single ended analog input, as recommended by the AD9653 datasheet for optimum performance. Inputs have 50Ω termination to ground, and are then coupled to ADC inputs via a 0.4 to 800 MHz balun.

The MZ523A complies with the MRT523 Mezzanine Interface Specification, which can be made available to research partners to allow them to develop their own application-specific mezzanine modules
