The CDCLVD2102 clock buffer distributes two clock inputs (IN0, IN1) to a total of 4 pairs of differential LVDS clock outputs (OUT0, OUT3). Each buffer block consists of one input and 2 LVDS outputs. The inputs can either be LVDS, LVPECL, or LVCMOS.

The CDCLVD2102 is specifically designed for driving 50- transmission lines. If driving the inputs in single ended mode, the appropriate bias voltage (VAC_REF) should be applied to the unused negative input pin.

Using the control pin (EN), outputs can be either disabled or enabled. If the EN pin is left open two buffers with all outputs are enabled, if switched to a logical "0" both buffers with all outputs are disabled (static logical "0"), if switched to a logical "1", one buffer with two outputs is disabled and another buffer with two outputs is enabled. The part supports a fail safe function. It incorporates an input hysteresis, which prevents random oscillation of the outputs in absence of an input signal.

The device operates in 2.5V supply environment and is characterized from –40°C to 85°C (ambient temperature). The CDCLVD2102 is packaged in small 16-pin, 3-mm × 3-mm QFN package.
