ADCMP572BCP-WP

Overview

The ADCMP572BCP-WP is a single-supply ultrafast 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 an equivalent input rise time bandwidth of 8 GHz. The device supports flexible power supply schemes with VCCI and VCCO ranges from 3.1 V to 5.4 V. It includes on-chip 50 Ω input terminations, resistor-programmable hysteresis, and robust input protection against phase reversal. Packaged in a 16-lead LFCSP, it operates over an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Ultrafast SiGe performance with 150 ps propagation delay and 8 GHz equivalent input bandwidth
• CML output stage designed for direct driving of 50 Ω transmission lines terminated to the VCCO supply
• Flexible dual-supply architecture supporting split input/output voltages or single-supply operation
• Integrated differential latch control and 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/zero-crossing detectors

Procurement Notes

Verify the specific ordering suffix WP corresponds to the tray packaging configuration when sourcing this component. Confirm that the voltage ratings and thermal requirements align with the target application's power dissipation limits. Ensure proper bypassing of VCCI and VCCO pins to maintain specified high-speed performance characteristics.

Selection Notes

Select the ADCMP572BCP-WP for applications requiring low jitter and precise timing resolution in high-speed environments. Consider the CML output compatibility with existing transmission line infrastructure. Evaluate the need for latch functionality versus continuous comparison mode based on system timing constraints.

Part Context

This component belongs to the ADCMP572/ADCMP573 family of ultrafast comparators manufactured by Analog Devices Inc. The ADCMP572 variant specifically utilizes Current Mode Logic (CML) outputs, distinguishing it from the RSPECL-output ADCMP573. Both share the same core SiGe technology and package footprint.

Replacement Considerations

The ADCMP573BCP-WP serves as a functional alternative within the same series, differing primarily in its RSPECL output driver instead of CML. Verify logic level compatibility and termination requirements before substitution.
