ADCMP582BCPZ-WP (ANALOG DEVICES)

The ADCMP582BCPZ-WP is an ultrafast SiGe Voltage Comparator fabricated on the proprietary XFCB3 Silicon Germanium (SiGe) bipolar process. The ADCMP582 features reduced swing PECL output drivers. The device offers 180ps propagation delay and 100ps minimum pulse width for 10Gbps operation with 200fs random jitter (RJ). Overdrive and slew rate dispersion are typically less than 15ps. The ±5V power supplies enable a wide -2 to 3V input range with logic levels referenced to the CML/NECL/PECL outputs. The inputs have 50R on-chip termination resistors with the optional capability to be left open for applications requiring high impedance input. The CML output stage is designed to directly drive 400mV into 50R transmission lines terminated to ground. The NECL output stages are designed to directly drive 400mV into 50R terminated to -2V. The differential latch input controls are also 50R terminated to an independent VTT pin to interface to either CML or ECL or to PECL logic.
