DEVICE DESCRIPTION
DATA SHEET
The GS9005A 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 GS9005A is packaged in a 28 pin PLCC operating from a
single +5 or -5 volt supply.
SPECIAL NOTE: R_VCO1 and R_VCO2 are functional over a
reduced temperature range of T_A=0° C to 50° C. R_VCO0
and R_VCO3 are functional over the full temperature range
of T_A=0° C to 70° C. This limitation does not affect
operation with the GS9010A ATS.
