GS2989 Dual-Slew-Rate, Dual-Output Cable Driver with 3Gb/s Capability

Features

Description

•

SMPTE 424M, SMPTE 292M and SMPTE 259M

The GS2989 is a high-speed BiCMOS integrated circuit

designed to drive one to four 75Ω coaxial cables.

compliant

•

Supports DVB-ASI at 270Mb/s

Supports data rates from 270Mb/s to 2.97Gb/s

Wide common-mode range input buffer

The GS2989 may drive data rates up to 2.97Gb/s and

provides two selectable slew rates in order to achieve

compliance to SMPTE 424M, SMPTE 292M and SMPTE

259M.

100mV sensitivity

The GS2989 accepts industry-standard differential input

levels including LVPECL and CML.

supports DC-coupling to industry-standard

differential logic

Input trace equalization compensates for up to 10 inches of

FR4 trace loss while in HD and 3G modes. This feature can

be disabled using the EQ_EN pin.

on-chip 100Ω differential data input termination

•

Input signal trace equalization

The DISABLE1 and DISABLE2 pins power-down the first

and second output drivers respectively, leaving the serial

data outputs in a high-impedance state. When applied

simultaneously, the entire device is powered-down.

Dual differential coaxial-cable-driving outputs

selectable slew rates

adjustable output swing from 500mVpp to

1800mVpp

The GS2989 features adjustable output swing using an

external bias resistor. The single-ended output swing is

adjustable from 500mVpp to 1800mVpp.

independent DISABLE controls for each output

•

Robust output signal presence function

Excellent output eye quality

An output signal presence function, the OSP pin, indicates

whether an active signal is present at the output of the

GS2989.

Power supply operation at 3.3V or 2.5V

110mW power consumption (2.5V supply)

Operating temperature range: -40°C to +85°C

Small footprint QFN package (4mm x 4mm)

The GS2989 can be powered from either a 3.3V or a 2.5V

supply. Power consumption is typically 110mW using a

2.5V power supply with one output enabled.

new dual-output pin out

The GS2989 is Pb-free, and the encapsulation compound

does not contain halogenated flame retardant.

use the GS2988 for a single-output variant that is

drop-in compatible to the GS2978

This component and all homogeneous subcomponents are

RoHS compliant.

•

Pb-free and RoHS compliant

Applications

•

SMPTE 424M, SMPTE 292M and SMPTE 259M coaxial

cable serial digital interfaces
