HD-LINX GS1504

HDTV Adaptive Equalizer

DATA SHEET

FEATURES

DESCRIPTION

• SMPTE 292M compliant

The GS1504 is a high performance cable equalizer

designed to equalize HDTV component signal conforming

to SMPTE 292M. The adaptive cable equalizer is capable of

equalizing up to 100m of Belden 8281 co-axial cable.

• Automatic, adjustment free cable equalization for

1.485Gb/s HDTV signals

• Differential serial outputs capable of driving 50Ω loads

The GS1504 features DC restoration for immunity to the DC

content in pathological test patterns. The device also

incorporates a Cable Length Indicator signal that provides

an indication of the amount of cable being equalized.

• Typically equalizes 100m of Belden 8281 or 150m of

Belden 1694 high quality co-axial cable

• Cable Length Indication

• Output Mute

A voltage programmable mute threshold (MCLADJ) is

included to allow muting of the GS1504 output when a

selected cable length is reached. This feature allows the

GS1504 to distinguish between low amplitude HD SDI

signals and noise at the input of the device. The CD/Mute

pin provides an indication of the GS1504 mute status in

addition to functioning as a mute control input. The output

of the GS1504 may be forced to an active or a mute

condition by applying a voltage to the CD/Mute pin.

• Maximum Cable Length Adjust

• Low power

• Minimal external components

• Single +5V or -5V power supply operation

• Pb-free and Green

APPLICATIONS

1.485Gb/s HDTV Serial Digital Receiver Interfaces for

Routers, Distribution Amplifiers, Switchers, and other

receiving equipment.

The GS1504 is a low power device that operates from a

single 5V power supply. The GS1504 is packaged in a

16 pin narrow SOIC and does not need external pull-up

resistors.
