Description
The GS1575A/9075A 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 GS1575A 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 GS9075A 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 GS1575A/9075A 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 GS1575A/9075A 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 GS1575A/9075A 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 GS1575A/9075A 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 GS1575A/9075A is Pb-free, and the encapsulation
compound does not contain halogenated flame
retardant.
This component and all homogeneous sub-components
are RoHS compliant.
