ADCMP563BCPZ-RL7

Overview

The ADCMP563BCPZ-RL7 is a dual high-speed ECL comparator fabricated on Analog Devices' proprietary XFCB process. It features a propagation delay of 700 ps with less than 75 ps overdrive dispersion. The device operates within an input common-mode range of −2.0 V to +3.0 V and provides differential ECL-compatible outputs fully compatible with ECL 10 K and 10 KH logic families. It includes latch inputs for track-and-hold or sample-and-hold modes, internal pull-ups, and power supply rejection greater than 85 dB. The component is housed in a 16-lead LFCSP package and supports an industrial temperature range from −40°C to +85°C.

Feature Summary

• Differential ECL-compatible outputs compatible with standard logic families
• Low propagation delay dispersion for consistent timing accuracy
• Integrated latch enable inputs supporting multiple operational modes
• Robust input protection against electrostatic discharge

Applications

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

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the BCPZ designation corresponds to the 16-lead LFCSP package variant. Ensure compatibility with required ECL termination voltages and supply rails during procurement planning.

Selection Notes

Select this model for applications requiring precise timing consistency across varying overdrive conditions. The dual-channel configuration allows independent processing of two signals. Verify that the system design accommodates the necessary negative supply voltage for proper ECL operation.

Part Context

This component belongs to the ADCMP563/ADCMP564 family of high-speed comparators. While the ADCMP564 adds programmable hysteresis functionality, the ADCMP563 focuses on core comparison performance. Both share the same XFCB fabrication technology and pinout structure for the LFCSP package.

Replacement Considerations

The ADCMP564 serves as a functional alternative if programmable hysteresis is required. Other series comparators may offer different output types but will lack the specific ECL compatibility and low dispersion characteristics.
