3 Description

The SN65HVD63 transceiver modulates and

demodulates signals between a logic (baseband) interface and a frequency suitable for long coaxial

media, to facilitate wired data transfer among radio

equipment.

The SN65HVD63 device is an integrated AISG

transceiver designed to meet the requirements of the

upcoming Antenna Interface Standards Group v3.0

specification.

The SN65HVD63 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.

The transmitter supports adjustable output power

levels from 0 dBm to 6 dBm delivered to the 50-Ω coax cable. The SN65HVD63 transmitter is compliant

with the spectrum emission requirement provided by

the AISG standard.

A direction control output facilitates bus arbitration for

an RS-485 interface. This device integrates an

oscillator input for a crystal, and also accepts

standard clock inputs to the oscillator.
