ADCLK905BCPZ-R7

ADCLK905 is a one input, one output, ultrafast clock/data buffer fabricated on the Analog Devices, Inc., proprietary XFCB3 silicon germanium (SiGe) bipolar process. It features full-swing emitter coupled logic (ECL) output drivers. For PECL (positive ECL) operation, bias VCC to the positive supply and VEE to ground. For NECL (negative ECL) operation, bias VCC to ground and VEE to the negative supply. The buffers offer 95ps propagation delay, 7.5GHz toggle rate, 10Gbps data rate, and 60fs random jitter (RJ). The inputs have centre tapped, 100 ohm, on-chip termination resistors. A VREF pin is available for biasing ac-coupled inputs. It is used in applications such as clock and data signal restoration and level shifting, automated test equipment (ATE), high speed instrumentation, high speed line receivers, threshold detection, converter clocking.
