NRL 12-Bit, 213 Msps ADC HSAD9 MCM Evaluation Board

摘要

The MCM Evaluation Board is a 6 inch by 6 inch test fixture designed for evaluating the HSAD9 MCM, a completely self contained ADC multichip module that digitizes incoming differential analog signals to 12 bit resolution at a 213 Msps maximum sample rate. Data is output through a 50 pin D connector with LYDS logic levels. The MCM Evaluation Board functions very similarly to the AMAD19 12 bit ADC Breadboard. Its circuitry is very similar as well, with the major components that were once on the Breadboard now packaged on the HSAD9 MCM. The MCM is comprised of five major circuit blocks: the AMAD19 custom GaAs HBT circuit, a Calibration FPGA, a non-volatile Ram, two octal, 8 bit DACs, and reference generation circuitry.
