DESCRIPTION
The GS1545 is a high performance integrated Equalizing
Receiver designed for HDTV component signals,
conforming to the SMPTE 292M standard. The GS1545
includes adjustment free, adaptive cable equalization, clock
and data recovery, and serial to parallel conversion.
The Equalizer stage features DC restoration for immunity to
the DC content in pathological test patterns.
The Clock and Data Recovery stage was designed to
automatically recover the embedded clock signal and
retime the data from SMPTE 292M compliant digital video
signals. There is also a selectable reclocked serial data
output and the ability to bypass the reclocker stage.
A unique feature, Input Jitter Indicator (IJI), is included for
robust system design. This feature is used to indicate
excessive input jitter before the chip mutes the outputs.
The Serial to Parallel conversion stage provides 1:20 S/P
conversion
The GS1545 uses the GO1515 external VCO connected to
the internal PLL circuitry to achieve ultra low noise PLL
performance.
