This document describes the features and characteristics of Analog Devices' Ultrafast SiGe Voltage Comparators ADCMP580/ADCMP581/ADCMP582, including 180ps propagation delay, 8GHz equivalent input rise time bandwidth, 10ps deterministic jitter, etc.
The ADCMP580/ADCMP581/ADCMP582 are ultrafast voltage comparators fabricated on Analog Devices' proprietary XFCB3 Silicon Germanium (SiGe) bipolar process. The family includes three variants: the ADCMP580 features CML output drivers, the ADCMP581 features reduced swing ECL (negative ECL) output drivers, and the ADCMP582 features reduced swing PECL (positive ECL) output drivers.
All three comparators offer 180 ps propagation delay and support 10 Gbps operation with a minimum pulse width of 100 ps. They feature on-chip terminations at both input pins, resistor-programmable hysteresis, and differential latch control. The devices are designed for applications such as automatic test equipment (ATE), high speed instrumentation, pulse spectroscopy, medical imaging, and high speed line receivers.
| Propagation Delay | 180 ps |
|---|---|
| Minimum Pulse Width | 100 ps |
| Output Rise/Fall Time | 37 ps typical |
| Deterministic Jitter (DJ) | 10 ps |
| Random Jitter (RJ) | 200 fs |
| Input Voltage Range | -2.0 V to +3.0 V |
The ADCMP580 features CML output drivers, the ADCMP581 features reduced swing ECL (negative ECL) output drivers, and the ADCMP582 features reduced swing PECL (positive ECL) output drivers.
The comparators offer a 100 ps minimum pulse width for 10 Gbps operation.
The typical output rise/fall time is 37 ps.
