SMPTE 259M Coaxial Cable Serial Digital Interfaces

DESCRIPTION

The GS9068 is a second generation high-speed bipolar

integrated circuit designed to drive one or two 75

Ω 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.
