APPLICATIONS
•
•
4ƒ
SC
and 4:2:2 serial digital interfaces
The GS9000D is packaged in a 28 pin PLCC and operates
Automatic standards select controller for serial routing
and distribution applications
from a single 5 volt, ±5% power supply.
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.
DEVICE DESCRIPTION
The GS9000D is a CMOS integrated circuit specifically
designed to deserialize SMPTE 259M serial digital signals
at data rates up to 270Mb/s. The GS9000D is a pin and
functional equivalent to the GS9000C, with the exception of
SDI input levels which are compatible for direct interfacing
to the GS7025, GS9025A and GS9035A.
The device incorporates a descrambler, serial to parallel
convertor, sync processing unit, sync warning unit and
automatic standards select circuitry.
