ADCMP573BCP-WP

Overview

The ADCMP573BCP-WP is an ultrafast comparator fabricated on a Silicon Germanium (SiGe) bipolar process. It features reduced swing PECL (RSPECL) output drivers and latch inputs, supporting single-supply operation at 3.3 V or 5.2 V. Key electrical specifications include a typical propagation delay of 150 ps, 8 GHz equivalent input rise time bandwidth, and 80 ps minimum pulse width. The device exhibits 15 ps overdrive and slew rate dispersion, with deterministic jitter of 10 ps and random jitter of 200 fs. It includes on-chip 50 Ω terminations at both input pins and offers resistor-programmable hysteresis.

Feature Summary

• Features RSPECL output drivers compatible with commonly used PECL logic families.
• Includes differential latch control for capturing input states prior to latching mode activation.
• Provides robust input protection against large overdrive without output phase reversal.
• Offers flexible power supply schemes supporting split or single-supply configurations.

Applications

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

Procurement Notes

Verify the specific suffix 'WP' indicates military-grade qualification or extended reliability standards as defined by Analog Devices. Confirm that the LFCSP package pinout matches the application board layout requirements. Ensure supply voltages adhere to the specified ranges for both input and output stages to maintain performance integrity.

Selection Notes

Select this component when RSPECL compatibility is required rather than standard CML outputs found in the ADCMP572 variant. Consider the device for applications demanding low propagation delay dispersion and high-speed latch functionality. Evaluate thermal management needs given the LFCSP package characteristics and operating temperature range.

Part Context

This part belongs to the ADCMP572/ADCMP573 family of ultrafast comparators. While the ADCMP572 utilizes CML outputs, the ADCMP573 specifically employs reduced swing PECL outputs. Both share identical input stages, SiGe fabrication processes, and latch capabilities, differing primarily in output driver topology and termination requirements.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing PECL logic families if replacing legacy components. Ensure interface voltage levels match the VCCO - 2 V termination requirement for proper signal integrity.
