Analog Devices Inc. ADCMP606BKSZ-R2

Overview

ADCMP606BKSZ-R2 from Analog Devices is a rail-to-rail, single-supply CML comparator optimized for high-speed signal conditioning in timing-critical systems. It delivers 1.25 ns propagation delay, 2.5 ps RMS random jitter, and operates from 2.5 V to 5.5 V supply with input common-mode range from −0.2 V to VCCI + 0.2 V. Used in clock/data restoration and high-speed line receivers where sub-nanosecond timing fidelity is required.

For engineers reviewing the ADCMP606BKSZ-R2 datasheet, ADCMP606BKSZ-R2 pinout, ADCMP606BKSZ-R2 application, or ADCMP606BKSZ-R2 equivalent, this page provides verified electrical specifications, SC70 package layout, CML output interface details, and real-world use cases including pulse-width modulation and threshold detection in ATE and instrumentation.

Technical Context

The ADCMP606BKSZ-R2 uses Analog Devices' XFCB2 process to achieve ultra-low propagation delay dispersion (<2.3 ns over 10–125 mV overdrive) and robust input stage protection against large overdrive without phase reversal. Its fully back-matched CML output drives 50 Ω loads directly with 300–500 mV differential swing referenced to VCCO.

It features rail-to-rail input operation with dual-front-end crossover bias points at ~0.6 V and ~1.6 V, enabling stable performance across full common-mode range. Input offset voltage is ±5 mV max, and power supply rejection exceeds 60 dB - critical for noise-sensitive high-speed data acquisition paths.

Key Specifications

Pinout & Package

FAQ

What is the maximum input overdrive the ADCMP606BKSZ-R2 can tolerate without phase reversal?

The ADCMP606BKSZ-R2 input stage is designed to prevent phase reversal even when inputs exceed the valid common-mode range. Per the datasheet, it tolerates input voltages from −0.5 V to VCCI + 0.5 V without output inversion - a key reliability feature for systems exposed to transient overvoltage events. This behavior is confirmed across −40°C to +125°C operation.

Does the ADCMP606BKSZ-R2 require external termination resistors for CML output operation?

No, the ADCMP606BKSZ-R2 integrates back-matched 50 Ω series termination on both Q and Q outputs. When driving a 50 Ω transmission line referenced to VCCO, no external resistors are needed - simplifying layout and minimizing signal reflections. External termination is only required if interfacing with non-50 Ω loads or different reference voltages.

Can the ADCMP606BKSZ-R2 operate with separate input and output supply voltages?

No - the ADCMP606BKSZ-R2 uses a single shared supply pin (VCCI/VCCO) for both input and output sections. For split-supply operation with independent VCCI and VCCO, the pin-compatible ADCMP607BKSZ-REEL7 must be used instead. This architectural difference is fundamental to the ADCMP606BKSZ-R2's compact SC70 footprint.

What is the minimum pulse width the ADCMP606BKSZ-R2 can reliably detect at 5.5 V supply?

At VCCI = VCCO = 5.5 V, the ADCMP606BKSZ-R2 supports a minimum input pulse width of 1.1 ns while maintaining 90% output fidelity (PWMIN specification). This enables accurate detection of narrow glitches and fast transient events in high-bandwidth monitoring circuits, provided proper PCB layout and bypassing are implemented.

Is the ADCMP606BKSZ-R2 RoHS compliant and lead-free?

Yes - the ADCMP606BKSZ-R2 is manufactured in a RoHS-compliant, lead-free process and meets JEDEC standard MO-203-AB for the SC70 package. The "BKSZ" suffix denotes lead-free, halogen-free, and green-compliant packaging per Analog Devices' environmental policy, with full compliance documentation available through authorized distributors.
