ADCMP582BCP-RL7

Overview

The ADCMP582BCP-RL7 is an ultrafast voltage comparator fabricated on the Analog Devices 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 a minimum pulse width of 100 ps, supporting 10 Gbps operation with 200 fs random jitter. It operates from ±5 V supplies, providing a wide input range of −2 V to +3 V. Key specifications include 37 ps typical output rise/fall time, >70 dB power supply rejection, and integrated 50 Ω on-chip input terminations.

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 via the HYS pin to enhance noise immunity.
• Includes 50 Ω on-chip input termination resistors at both VP and VN pins.

Applications

• Automatic test equipment (ATE)
• High speed instrumentation
• Medical imaging and diagnostics

Procurement Notes

Verify that the specific suffix BCP indicates the correct package variant and reel configuration required for your assembly line. Confirm that the PECL output stage aligns with your system's logic levels and termination requirements. Ensure that the ordering documentation matches the exact part number to avoid discrepancies in electrical characteristics or packaging specifications.

Selection Notes

Select this component when PECL compatibility is required alongside ultrafast response times. The ADCMP582 differs from the ADCMP580 (CML) and ADCMP581 (NECL) primarily by its positive ECL output stage. Consider the ±5 V supply requirement and the need for external termination networks referencing VCCO − 2 V for optimal signal integrity in high-speed designs.

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 performance, they are distinguished by their output driver types: CML, NECL, and PECL respectively. This specific model utilizes the PECL architecture, making it suitable for applications requiring positive ECL signaling standards.

Replacement Considerations

Direct functional replacements within the same family include ADCMP580BCPZ-RL7 and ADCMP581BCPZ-RL7, provided the output logic level differences (CML vs. PECL vs. NECL) are accommodated by the circuit design.
