Description
The GS1578A is a second generation high-speed
BiCMOS integrated circuit designed to drive one or two
75Ω co-axial cables.
The GS1578A 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 GS1578A 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 GS1578A is Pb-free, and the
encapsulation compound does not contain halogenated
flame retardant.
This component and all homogeneous subcomponents
are RoHS compliant.
