Introduction
This user’s guide details the evaluation module (EVM) operation of factory installed SN65HVD62 AISG On
Off Keying Coax Modem Transceivers. The EVM may be configured to evaluate one SN65HVD62 IC in a
stand-alone configuration or to hook up two EVMS in a system scenario with one acting as a transmitter
while the other acts as the receiver and vice-versa.

Overview
SN65HVD62 is an integrated AISG transceiver designed to be compliant with the Antenna Interface
Standards Group v2.0 specification.
Standards Group v2.0 specification.
The receive channel integrates an active bandpass filter to enable demodulation of signals even in the
presence of spurious frequency components.
