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 of GS1545 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 of GS1545 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.
