DEVICE DESCRIPTION
The GS9000C is a CMOS integrated circuit specifically
designed to deserialize SMPTE 259M serial digital signals
at data rates to 370Mb/s.
The device incorporates a descrambler, serial to parallel
convertor, sync processing unit, sync warning unit and
automatic standards select circuitry.
Differential pseudo-ECL inputs for both serial clock and
data are internally level shifted to CMOS levels. Digital
outputs such as parallel data, parallel clock, HSYNC,
Sync Warning and Standard Select are all TTL compatible.
The GS9000C is designed to directly interface with the
GS9005A Reclocking Receiver to form a complete
SMPTE-serial-in to CMOS level parallel-out deserializer.
The GS9000C may also be used with the GS9010A and
the GS9005A to form an adjustment-free receiving system
which automatically adapts to all serial digital data rates.
The GS9015A can replace the GS9005A in GS9000C
applications where cable equalization is not required.
The GS9000C is packaged in a 28 pin PLCC and operates
from a single 5 volt,
±
5% power supply.
