Description

The GS1528 is a second generation high-speed bipolar

integrated circuit designed to drive one or two 75Ω

co-axial cables at data rates up to 1.485Gb/s. The GS1528

provides two selectable slew rates in order to achieve

compliance to SMPTE 259M, SMPTE 344M and SMPTE

292M.

The GS1528 accepts a LVPECL level differential input that

may be AC-coupled. External biasing resistors at the inputs

are not required.

Power consumption is typically 160mW using a 3.3V power

supply.

This component and all homogeneous subcomponents are

RoHS compliant.
