ADCMP572BCP-R2

Overview

The ADCMP572BCP-R2 is an ultrafast single-supply comparator fabricated on Analog Devices' proprietary XFCB3 Silicon Germanium (SiGe) bipolar process. It features CML output drivers and operates with a supply voltage range of 3.1 V to 5.4 V for both input (VCCI) and output (VCCO). The device provides a propagation delay of 150 ps, overdrive dispersion of less than 15 ps, and an equivalent input rise time bandwidth of 8 GHz. It includes on-chip 50 Ω input terminations, resistor-programmable hysteresis, differential latch control, and robust inputs that prevent output phase reversal.

Feature Summary

• Features CML output drivers designed to directly drive transmission lines terminated between 3.3 V and 5.2 V.
• Includes on-chip 50 Ω termination resistors at both input pins with the option to be left open for high impedance applications.
• Provides robust input protection against large overdrive without causing output phase reversal.
• Supports flexible power schemes allowing single or split input/output supplies for independent signal ranges.

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 ordering suffix R2 corresponds to the required tape and reel packaging configuration. Confirm that the LFCSP package dimensions and thermal characteristics align with the target PCB layout requirements. Ensure the design accounts for the extended industrial temperature range specifications during procurement planning.

Selection Notes

Select this component when ultrafast propagation delay and low jitter are critical for high-speed signal processing. The CML output interface is suitable for driving 50 Ω transmission lines in high-frequency environments. Consider the integrated latch functionality if holding the comparison state is necessary for the application timing requirements.

Part Context

This part belongs to the ADCMP572/ADCMP573 family of ultrafast comparators manufactured using SiGe technology. While the ADCMP573 variant utilizes RSPECL outputs, the ADCMP572 specifically employs CML drivers. Both share identical electrical performance metrics regarding delay, jitter, and input characteristics within the same 16-lead LFCSP package.
