HD-LINX^™GS1545

HDTV Serial Digital

Equalizing Receiver

PRELIMINARY DATA SHEET

FEATURES

DESCRIPTION

• SMPTE 292M compliant

• 1.485 and 1.485/1.001Gb/s operation

• integrated adaptive cable equalizer

• integrated adjustment-free reclocker

• 1:20 serial to parallel conversion

• selectable reclocked serial output

• analog/digital input MUX

• carrier detect

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.

• LOCK detect

• input jitter indicator (IJI)

• cable length indication

• maximum cable length adjust

• 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

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

conversion

• minimal component count for HD SDI receive

solutions

The GS1545 uses the GO1515 external VCO connected to

the internal PLL circuitry to achieve ultra low noise PLL

performance.
