ADCMP582BCPZ-R2

Overview

The ADCMP582BCPZ-R2 is an ultrafast voltage comparator fabricated on Analog Devices' proprietary XFCB3 Silicon Germanium (SiGe) bipolar process. It features reduced swing PECL output drivers designed to directly drive 400 mV into 50 Ω transmission lines terminated to VCCO − 2 V. The device offers a propagation delay of 180 ps and supports 10 Gbps operation with 200 fs random jitter. It operates with ±5 V supplies, providing a wide input range from −2 V to +3 V. Key specifications include 100 ps minimum pulse width, 37 ps typical rise/fall time, and overdrive dispersion typically less than 15 ps.

Feature Summary

• Features reduced swing PECL output drivers for direct interfacing with high-speed logic families.
• Incorporates differential latch control with internal 50 Ω termination for precise signal acquisition.
• Provides resistor-programmable hysteresis to enhance noise immunity in threshold detection applications.
• Includes on-chip 50 Ω input termination resistors with optional disable capability for flexible impedance matching.

Applications

• Automatic test equipment (ATE)
• High speed instrumentation
• Medical imaging and diagnostics
• Clock and data signal restoration

Procurement Notes

Verify the specific ordering suffix matches the required reel packaging configuration. Confirm that the PECL output variant aligns with system logic levels. Ensure supply voltages adhere to the specified ±5 V requirements for optimal performance. Check thermal management needs due to power dissipation characteristics in the LFCSP package.

Selection Notes

Select this component when PECL compatibility is required alongside ultrafast switching speeds. Consider the ADCMP580 or ADCMP581 if CML or NECL outputs are preferred instead. Evaluate the need for latch functionality, as disabling it requires specific external resistor configurations. Ensure the PCB layout supports low-inductance return paths for the VEE and VCCO supplies.

Part Context

This part belongs to the ADCMP580/ADCMP581/ADCMP582 family of ultrafast SiGe comparators. All variants share identical input characteristics and propagation delay but differ in output driver type. The ADCMP582 specifically utilizes PECL outputs, distinguishing it from the CML-based ADCMP580 and NECL-based ADCMP581 within the same silicon platform.
