SLLSE94C – SEPTEMBER 2011 – REVISED MARCH 2015

SN65HVD62 AISG On-Off Keying Coax Modem Transceiver

1 Features

3 Description

These transceivers modulate and demodulate signals

1

•

Supply Ranging From 3V to 5.5V

between the logic (baseband) and a frequency

•

Independent Logic Supply of 1.6V to 5.5V

suitable for long coaxial media.

•

Wide Input Dynamic Range of –15dBm to +5dBm

The HVD62 is an integrated AISG transceiver

for Receiver

designed to be compliant with Antenna Interface

•

Power Delivered by the Driver to the Coax can be

Standards Group v2.0 specification.

Adjusted From 0dBm to +6dBm

The HVD62 receiver integrates an active bandpass
