ADCMP563BRQ

Overview

The ADCMP563BRQ is a dual high-speed ECL comparator manufactured by Analog Devices Inc. on the proprietary XFCB process. It features a 700 ps propagation delay and less than 75 ps overdrive dispersion. The device operates within an input common-mode range of -2.0 V to +3.0 V, with outputs fully compatible with ECL 10K and 10KH logic families. It supports latch inputs for tracking, track-and-hold, or sample-and-hold modes. The component is specified for industrial temperatures from -40°C to +85°C and utilizes a 16-lead QSOP package.

Feature Summary

• Differential ECL-compatible outputs providing sufficient drive current for direct transmission line termination
• Differential latch control enabling tracking, track-and-hold, or sample-and-hold operational modes
• Robust input protection and internal latch pull-up resistors for simplified interface design

Applications

• Automatic test equipment
• High speed instrumentation
• Scope and logic analyzer front ends
• Window comparators
• Clock drivers

Procurement Notes

Verify the specific ordering suffix BRQ corresponds to the 16-lead QSOP package variant when sourcing. Confirm that the procurement channel provides documentation matching the Rev. D datasheet specifications. Ensure compatibility with standard ECL power supply configurations (-5.2V/5V) during acquisition planning.

Selection Notes

Select this component for applications requiring consistent propagation delay across varying signal types. The differential input stage ensures reliable performance within the specified common-mode voltage range. Consider the available latch functionality if timing capture or sampling operations are required in the system architecture.

Part Context

This part belongs to the ADCMP563/ADCMP564 family of high-speed comparators fabricated using Analog Devices' XFCB technology. While the ADCMP564 includes programmable hysteresis capabilities via dedicated pins, the ADCMP563 focuses on core comparison and latching functions. Both share identical electrical characteristics regarding speed and output drive capabilities.
