DEVICE DESCRIPTION
The GS9005B is a monolithic IC designed to receive SMPTE
259M serial digital video signals. This device performs the
functions of automatic cable equalization and data and clock
recovery.
It interfaces directly with the
GENLINX™
GS9000B or GS9000S decoder, and GS9010A Automatic
Tuning Subsystem.
The VCO centre frequencies are controlled by external resistors
which can be selected by applying a two bit binary code to the
Standards Select input pins.

An additional feature is the Signal Strength Indicator output
which provides a 0.5V to 0V analog output relative to V
CC
indicating the amount of equalization being applied to the
signal.
The GS9005B is packaged in a 28 pin PLCC operating from
a single +5 or -5 volt supply.
