The MAX3812 is a multirate SMPTE cable driver

designed to operate at data rates up to 1.485Gbps,

driving one or two 75Ω coaxial cables. Two selectable

slew rates are provided for compliance to SMPTE 292M,

SMPTE 344M, and SMPTE 259M. The MAX3812 is pin

compatible with the Gennum GS1528.

The MAX3812 inputs are internally biased and compatible

with differential swings of CML, LVPECL, and LVDS.

Output voltage swing is adjustable with a single

external resistor.

The MAX3812 operates over a 0°C to +85°C temperature

range. It typically consumes 106mW with a +3.3V power

supply and is available in an 8-pin SO package.

19-3571; Rev 0; 2/05
