Description
The GS1575B/9075B is a Multi-Rate Serial Digital Reclocker
designed to automatically recover the embedded clock
from a digital video signal and re-time the incoming video
data.
The GS1575B Serial Digital Reclocker will recover the
embedded clock signal and re-time the data from a SMPTE
292M, SMPTE 259M or SMPTE 344M compliant digital
video signal.
The GS9075B Serial Digital Reclocker will recover the
embedded clock signal and re-time the data from a SMPTE
259M or SMPTE 344M compliant digital video signal.
The GS1575B/9075B removes the high frequency jitter
components from the bit-serial stream. Input termination is
on-chip for seamless matching to 50Ω transmission lines.
An LVPECL compliant output interfaces seamlessly to the
GS1578A/GS9078A Cable Driver.
The GS1575B/9075B can operate in either auto or manual
rate selection mode. In Auto mode the device will
automatically detect and lock onto incoming SMPTE SDI
data signals at any supported rate. For single rate data
systems, the GS1575B/9075B can be configured to operate
in Manual mode. In both modes, 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 GS1575B/9075B can be configured to either
automatically or manually enter a bypass mode in order to
pass the signal without reclocking.
The ASI/177 input pin allows for manual selection of
support of either 177Mb/s or DVB-ASI inputs.
The GS1575B/9075B is Pb-free, and the encapsulation
compound does not contain halogenated flame retardant.
This component and all homogeneous sub-components are
RoHS compliant.
