GS1528 Data Sheet
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.
