3 Description
These transceivers modulate and demodulate signals
between the logic (baseband) and a frequency suitable for long coaxial media.
The HVD62 is an integrated AISG transceiver designed to be compliant with Antenna Interface
Standards Group v2.0 specification.
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.
The transmitter supports adjustable output power
levels varying from +0dBm to +6dBm delivered to the
50 Ω coax cable. The HVD62 transmitter is compliant
with the spectrum emission requirement provided by
the AISG standard.
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.
