AISG® 3.0 on and off keying coax modem transceiver with wide temperature range

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.
