ADCMP582BCP-R2

Overview

The ADCMP582BCP-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 a minimum pulse width of 100 ps. It operates with ±5 V power supplies, enabling a wide input range from −2 V to +3 V. Integrated features include 50 Ω on-chip input terminations, resistor-programmable hysteresis, and differential latch control.

Feature Summary

• Features reduced swing PECL output drivers for direct interfacing with high-speed logic families.
• Incorporates internal 50 Ω termination resistors at both analog input pins for impedance matching.
• Provides programmable hysteresis via the HYS control pin to prevent output oscillation.
• Includes differential latch enable inputs with independent termination for signal acquisition.

Applications

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

Procurement Notes

Verify that the specific suffix matches the required package and reel configuration. Confirm supply voltage requirements align with the ±5 V specification. Ensure PCB layout accommodates the 16-lead LFCSP footprint and thermal dissipation needs. Check datasheet for absolute maximum ratings to prevent damage during integration.

Selection Notes

Select this component when PECL logic compatibility is required alongside ultrafast response times. Consider the ADCMP580 or ADCMP581 if CML or NECL outputs are preferred instead. Evaluate the need for latch functionality, as it adds setup and hold time constraints. Verify that the system can support the necessary dual power supply rails for optimal performance.

Part Context

This device belongs to the ADCMP580/ADCMP581/ADCMP582 family of ultrafast SiGe voltage comparators. While all three share identical propagation delay and jitter specifications, they differ in output stage technology. The ADCMP582 specifically utilizes PECL outputs, distinguishing it from the CML-based ADCMP580 and the NECL-based ADCMP581 within the same package.

Replacement Considerations

Direct functional substitutes within the same family include the ADCMP580 and ADCMP581, provided the output logic levels (CML or NECL) are compatible with the downstream circuitry. No other cross-family replacements are confirmed by official documentation.
