ADCLK925BCPZ-R7

ADCLK925 (one input, two outputs) is an ultrafast clock/data buffer fabricated on the Analog Devices, Inc., proprietary XFCB3 silicon germanium (SiGe) bipolar process. It feature 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 inputs have centre tapped, 100 ohm, on-chip termination resistors. A VREF pin is available for biasing ac-coupled inputs. The ECL output stages are designed to directly drive 800mV each side into 50 ohm terminated to VCC − 2V for a total differential output swing of 1.6V. It is widely used in application 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 etc.
