GENLINX GS9000C
Serial Digital Decoder
DATA SHEET
DEVICE DESCRIPTION
FEATURES
The GS9000C is a CMOS integrated circuit specifically
designed to deserialize SMPTE 259M serial digital signals
at data rates to 370Mb/s.
•
•
fully compatible with SMPTE 259M
decodes 8 and 10 bit serial digital signals for 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.
•
pin and function compatible with GS9000S, GS9000
and GS9000B
•
•
325mW power dissipation at 270MHz clock rates
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.
incorporates an automatic standards selection
function with the GS9005A Receiver or GS9015A
Reclocker
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.
•
•
operates from single +5 or -5 volt supply
enables an adjustment-free Deserializer system
when used with GS9010A and GS9005A or
GS9015A
•
28 pin PLCC packaging
APPLICATIONS
•
•
4ƒSC, 4:2:2 and 360Mb/s serial digital interfaces
The GS9000C is packaged in a 28 pin PLCC and operates
from a single 5 volt, ±5% power supply.
Automatic standards select controller for serial routing
and distribution applications using GS9005A Receiver or
