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.
