1 The signaling rate of a line is the number of voltage transitions that are made per second expressed in the units bps (bits per second).

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- 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-uF capacitor and limit the current sourcing or sinking to 400 uA. When not used, VBB should be left open.

This device is characterized for operation from –40°C to 85°C.
