ADCMP573BCPZ-R2

Overview

The ADCMP573BCPZ-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 operates with a single 3.3 V or 5.2 V positive supply, providing flexible input signal ranges from −0.2 V to +1.2 V or up to +3.2 V with split supplies. It includes 50 Ω on-chip input terminations, robust input protection against phase reversal, resistor-programmable hysteresis, and differential latch control.

Feature Summary

• Features RSPECL output drivers compatible with common PECL logic families
• Includes differential latch control for capturing input states at specific times
• Provides resistor-programmable hysteresis via the HYS pin
• Offers robust input protection that prevents output phase reversal during overdrive

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 R2 corresponds to tape and reel packaging when sourcing components. Confirm that the RSPECL output voltage levels align with the receiving logic family termination requirements, typically VCCO minus 2 V. Ensure proper bypassing of both VCCI and VCCO supplies to maintain specified jitter performance.

Selection Notes

Select this component over the ADCMP572 when PECL compatibility is required rather than CML. Consider the extended industrial temperature range of −40°C to +125°C for harsh environments. Evaluate the need for latch functionality, as it adds setup and hold time constraints compared to continuous comparison mode.

Part Context

This part belongs to the ADCMP572/ADCMP573 family of ultrafast comparators designed for high-speed applications. While the ADCMP572 provides CML outputs, the ADCMP573 variant specifically targets systems requiring reduced swing PECL signaling. Both share identical input characteristics and SiGe fabrication processes.
