ADCMP573BCP-R2

Overview

The ADCMP573BCP-R2 is an ultrafast comparator fabricated on Analog Devices' proprietary XFCB3 Silicon Germanium (SiGe) bipolar process. It features reduced swing PECL (RSPECL) output drivers and latch inputs, offering a propagation delay of 150 ps and a minimum pulse width of 80 ps for 10 Gbps operation. The device supports flexible power supply schemes with single 3.3 V or split input/output supplies, providing robust protection against large input overdrive without phase reversal. It includes on-chip 50 Ω input terminations and resistor-programmable hysteresis.

Feature Summary

• Features RSPECL output drivers compatible with common PECL logic families
• Includes differential latch control for capturing input states
• Provides robust input protection preventing output phase reversal during overdrive
• Offers resistor-programmable hysteresis for noise immunity

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm the package type and reel configuration. Ensure the design accounts for the required VCCO termination voltage of VCCO minus 2 V for the RSPECL outputs. Confirm that the application environment operates within the specified extended industrial temperature range of −40°C to +125°C.

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 needing high-speed threshold detection with minimal jitter. Evaluate the need for split supply capabilities if wider input signal ranges are necessary compared to single-supply configurations.

Part Context

This part belongs to the ADCMP572/ADCMP573 family of ultrafast comparators designed for high-speed data communication and instrumentation. While the ADCMP572 utilizes CML outputs, the ADCMP573 specifically integrates RSPECL drivers. Both share identical input characteristics, propagation delays, and latch functionalities, differing primarily in their output stage compatibility.

Replacement Considerations

The ADCMP572BCPZ-RL7 serves as a functional substitute but utilizes CML outputs instead of RSPECL. Verify that the target system can accommodate the different output voltage levels and termination requirements associated with CML signaling before substituting.
