ADCMP572BCPZ-RL7

Overview

The ADCMP572BCPZ-RL7 is an ultrafast single-supply comparator fabricated on Analog Devices' proprietary XFCB3 Silicon Germanium (SiGe) bipolar process. It features CML output drivers and latch inputs, offering a propagation delay of 150 ps and 80 ps minimum pulse width for 10 Gbps operation with 200 fs rms random jitter. The device operates on a single 3.3 V or 5.2 V positive supply, providing robust input protection against large overdrive without phase reversal. It includes 50 Ω on-chip input terminations and resistor-programmable hysteresis.

Feature Summary

• Ultrafast SiGe performance with 150 ps propagation delay and 8 GHz equivalent input bandwidth
• CML output stage designed to directly drive 400 mV into 50 Ω transmission lines
• Integrated 50 Ω input termination resistors with optional disable capability
• Resistor-programmable hysteresis and differential latch control 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/zero-crossing detectors

Procurement Notes

Verify the specific suffix RL7 indicates tape and reel packaging when sourcing. Confirm that the B grade corresponds to the extended industrial temperature range of -40°C to +125°C. Ensure the LFCSP-16 package footprint matches your PCB design guidelines. Check for RoHS compliance documentation as required by your manufacturing standards.

Selection Notes

Select this component for applications requiring low deterministic jitter and high-speed threshold detection. The CML output is suitable for driving 50 Ω transmission lines directly. Consider the ADCMP573 if RSPECL outputs are preferred instead of CML. Ensure power supply decoupling meets high-frequency requirements to maintain specified jitter performance.

Part Context

This part belongs to the ADCMP572/ADCMP573 family of ultrafast comparators. Both devices share the same core SiGe architecture but differ in output driver type. The ADCMP572 provides CML outputs, while the ADCMP573 offers reduced swing PECL (RSPECL) outputs. They are housed in identical 16-lead LFCSP packages.

Replacement Considerations

The ADCMP573BCPZ-RL7 is a functional alternative within the same family, differing only in output driver type (RSPECL vs. CML). Verify pin compatibility and output voltage levels before substitution.
