Description
The GS1528A/9068A is a second generation, high speed
BiCMOS integrated circuit designed to drive one or two
75W coaxial cables.
The GS1528A 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 GS9068A may drive data rates up to 540Mb/s and will
achieve compliance to SMPTE 259M and SMPTE 344M.
The GS1528A/9068A 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 GS1528A/9068A is
Pb-free, and the encapsulation compound does not contain
halogenated flame retardant. This component and all
homogeneous sub components are RoHS compliant.
