Description

The GS1528B is a second generation high-speed BiCMOS

integrated circuit designed to drive one or two 75Ω co-axial

cables.

The GS1528B may drive data rates up to 1.485Gb/s and

provides two selectable slew rates in order to achieve

compliance to SMPTE 259M, SMPTE 344M and SMPTE

292M.

The GS1528B accepts a LVPECL level differential input that

may be AC coupled. External biasing resistors at the inputs

are not required.

Power consumption is typically 168mW using a 3.3V

power supply.

The GS1528B is Pb-free, and the encapsulation compound

does not contain halogenated flame retardant.

This component and all homogeneous subcomponents are

RoHS compliant.
