GS9076 Data Sheet
Description
The GS9076 is an SD-SDI Serial Digital Reclocker
designed to automatically recover the embedded clock
from a digital video signal and re-time the incoming
video data. The device automatically detects and locks
to incoming SMPTE 259M-C SDI and DVB-ASI signals
at 270Mb/s.
The GS9076 removes the high frequency jitter
components from the bit-serial stream. Input
termination is on-chip for seamless matching to 50Ω
transmission lines. The device requires only one
external crystal to set the VCO frequency when not
locked and provides adjustment free operation.
In systems which require passing of non-SMPTE data
rates, the GS9076 can be configured to either
automatically or manually enter a bypass mode in order
to pass the signal without reclocking.
The GS9076 offers a choice of dual reclocked data
outputs or one data output and one recovered clock
output. The device is footprint and drop-in compatible
with existing GS2975A designs, with no additional
application changes required.
The GS9076 is Pb-free, and the encapsulation
compound does not contain halogenated flame
retardant.
This component and all homogeneous sub-components
are RoHS compliant.
