DESCRIPTION The GS1540 is a high performance integrated Receiver designed for HDTV component signals, conforming to the SMPTE 292M standard. The GS1540 includes adjustment- free clock and data recovery, and 1:20 serial to parallel conversion. The Clock and Data Recovery stage was designed to auto- matically recover the embedded clock signal and re-time the data from SMPTE 292M compliant digital video signals. There is also a selectable reclocked serial data buffer out- put 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 GS1540 uses the GO1515 external VCO connected to the internal PLL circuitry to achieve ultra low noise PLL performance.
