General Description

The MAX2112 evaluation kit (EV kit) simplifies the test-

ing and evaluation of the IC direct-conversion tuner.

The evaluation kit is fully assembled and tested at the

factory. Standard 50Ω SMA and BNC connectors are

included on the EV kit for the inputs and outputs to

allow quick and easy evaluation on the test bench.

This document provides a list of equipment required to

evaluate the device, a straightforward test procedure to

verify functionality, a description of the EV kit circuit, the

circuit schematic, a component list for the kit, and art-

work for each layer of the PCB.

The supply current from the 3.3V VCC supply should read approximately 100mA, and the supply current from the 3V VGC should read approximately 50µA. Be sure to adjust the power supply to account for any voltage drop across the ammeter. 8) Install and run the IC control software.
