ADCMP563BCPZ-R2

Overview

The ADCMP563BCPZ-R2 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 compatible with ECL 10K and 10KH logic families. It includes latch enable inputs for track-and-hold or sample-and-hold modes, internal pull-up resistors, and power supply rejection greater than 85 dB. The component supports a minimum pulse width of 700 ps and offers ESD protection exceeding 4 kV HBM.

Feature Summary

• Differential ECL-compatible outputs fully compatible with standard ECL logic families
• Integrated latch enable inputs supporting tracking, track-and-hold, and sample-and-hold operations
• High power supply rejection ratio exceeding 85 dB for stable performance
• Robust input protection capabilities including significant electrostatic discharge tolerance

Applications

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

Procurement Notes

Verify the specific suffix R2 against the manufacturer's current ordering guide to confirm packaging details and availability status. Ensure that the LFCSP package variant matches the required footprint dimensions and thermal characteristics for the target PCB layout. Confirm that the industrial temperature rating aligns with the operational environment requirements before finalizing procurement orders.

Selection Notes

Select this component when differential ECL signaling is required for high-speed applications. The dual-channel architecture allows for independent processing of two signals within a single package. Consider the latch functionality if signal acquisition timing control is necessary. Verify that the system can provide the required negative supply voltage for proper ECL termination and operation.

Part Context

This part belongs to the ADCMP563/ADCMP564 family of high-speed comparators manufactured by Analog Devices Inc. utilizing the XFCB process technology. The ADCMP563 variant specifically lacks the programmable hysteresis feature found in the ADCMP564 model. Both devices share identical electrical characteristics regarding propagation delay and output drive capabilities, differing primarily in hysteresis configuration options.

Replacement Considerations

The ADCMP564BCPZ-R2 serves as a direct functional substitute, offering identical specifications with the addition of programmable hysteresis capability. Designers requiring fixed hysteresis may find the ADCMP563 suitable, while those needing adjustable thresholds should consider the ADCMP564. No other cross-model replacements are documented in the provided datasheet.
