3 Description
The SN65HVD64 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 SN65HVD64 device is an integrated AISG
transceiver designed to meet the requirements of the
Antenna Interface Standards Group v2.0 and v3.0
specification.
The SN65HVD64 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 SN65HVD64 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.
