Adaptive Cable Equalizer

GS1574 Preliminary Data Sheet

Features

Description

•

SMPTE 292M, SMPTE 344M and SMPTE 259M

The GS1574 is a second-generation high-speed bipolar

integrated circuit designed to equalize and restore

compliant

•

Automatic cable equalization

Multi-standard operation from 143Mb/s to 1.485Gb/s

Supports DVB-ASI at 270Mb/s

Small footprint (4mm x 4mm)

Pb-free and Green

co-axial cable.

The GS1574 is designed to support SMPTE 292M,

SMPTE 344M and SMPTE 259M, and is optimized for

performance at 270Mb/s and 1.485Gb/s.

Pin compatible with the GS9074 Cable Equalizer

Manual bypass (useful for low data rates with slow

The GS1574 features DC restoration to compensate for

the DC content of SMPTE pathological test patterns.

rise/fall times)

•

Performance optimized for 270Mb/s and 1.485Gb/s

Typical maximum equalized length of Belden 1694A

A voltage programmable mute threshold (MCLADJ) is

included to allow muting of the GS1574 output when an

approximate selected cable length is reached for

SMPTE 259M signals. This feature allows the GS1574

to distinguish between low amplitude SD-SDI signals

and noise at the input of the device. The serial digital

outputs of the GS1574 may be forced to a mute state by

applying a voltage to the MUTE pin.

cable: 140m at 1.485Gb/s, 350m at 270Mb/s

•

50Ω differential output (with internal 50Ω pull-ups)

Manual output mute or programmable mute based on

max cable length adjust

•

Single 3.3V power supply operation

Operating temperature range: 0°C to +70°C

Applications

•

SMPTE 292M, SMPTE 344M and SMPTE 259M Coaxial

Cable Serial Digital Interfaces.

Power consumption is typically 270mW using a 3.3V

power supply. The GS1574 is lead-free, and the

encapsulation compound does not contain halogenated

flame retardant.
