HDTV Serial Digital

Non-Equalizing Receiver

PRELIMINARY DATA SHEET

FEATURES

DESCRIPTION

• SMPTE 292M compliant

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.

• 1.485 and 1.485/1.001Gb/s operation

• integrated adjustment-free reclocker

• 1:20 serial to parallel conversion

• selectable reclocked serial output

• reclocker BYPASS capability

• LOCK detect

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

buffer output and the ability to bypass the reclocker stage.

• input jitter indicator (IJI)

• 20 bit output

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.

• 74.25MHz or 74.25/1.001MHz clock output

• single +5.0V power supply

• minimal component count for HD SDI receive

solutions

The Serial to Parallel conversion stage provides 1:20 S/P

conversion.

APPLICATIONS

The GS1540 uses the GO1515 external VCO connected to

the internal PLL circuitry to achieve ultra low noise PLL

performance.
