DESCRIPTION

This high-speed translator/repeater is designed for

signaling rates up to 1.5 Gbps to support various

high-speed network routing applications. The driver

output is compatible with current-mode logic (CML) levels, and directly drives 50-W or 25-W loads

connected to 1.8-V, 2.5-V, or 3.3-V nominal supplies.

The capability for direct connection to the loads may

eliminate the need for coupling capacitors. The

receiver input is compatible with LVDS (TIA/EIA-644), LVPECL, and CML signaling levels. The receiver

tolerates a wide common-mode voltage range, and

may also be directly coupled to the signal source.

The internal data path from input to output is fully

differential for low noise generation and low

pulse-width distortion.

The VBB pin is an internally generated voltage supply

to allow operation with a single-ended LVPECL input.

For single-ended LVPECL input operation, the

unused differential input is connected to VBB as a

switching reference voltage. When used, decouple

VBB with a 0.01-mF capacitor and limit the current

sourcing or sinking to 400 mA. When not used, VBB

should be left open.

This device is characterized for operation from –40°C

to 85°C.
