AISG On-Off Keying Coax Modem Transceiver

Check for Samples: SN65HVD62

FEATURES

DESCRIPTION

These transceivers modulate and demodulate signals

between the logic (baseband) and a frequency

suitable for long coaxial media.

•

Supply Ranging From 3V to 5.5V

Independent Logic Supply of 1.6V to 5.5V

Wide Input Dynamic Range of –15dBm to

+5dBm for Receiver

The HVD62 is an integrated AISG transceiver

designed to be compliant with Antenna Interface

Standards Group v2.0 specification.

•

Power Delivered by the Driver to the Coax can

be Adjusted From +3dBm to +6dBm

The HVD62 receiver integrates an active bandpass

filter to enable demodulation of signals even in the

presence of spurious frequency components. The

filter has a 2.176 MHz center frequency.

•

AISG Compliant Output Emission Profile

Low-power Standby Mode

Direction Control Output for RS-485 Bus

Arbitration

The transmitter supports adjustable output power

levels varying from +3dBm to +6dBm delivered to the

50 Ω coax cable. The HVD62 transmitter is compliant

with the spectrum emission requirement provided by

the AISG standard.

•

Supports up to 115 kbps Signaling

Integrated Active Bandpass Filter in the

Receiver Path with Center Frequency at

2.176MHz

A direction control output is provided which facilitates

bus arbitration for an RS-485 interface. These

devices integrate an oscillator input for a crystal, and

also accept standard clock inputs to the oscillator.
