Description
The GS9068 is a second generation high-speed bipolar
integrated circuit designed to drive one or two 75Ω co-axial
cables at data rates up to 540Mb/s.
The GS9068 accepts a LVPECL level differential input,
which may be AC-coupled. External biasing resistors at the
inputs are not required.
Power consumption is typically 160mW using a +3.3V DC
power supply.
