ADCLK907BCPZ-R2

Clock Buffers, Drivers Overview

The ADCLK907BCPZ-R2 is a dual 1:1 ultrafast clock and data buffer fabricated on Analog Devices' proprietary XFCB3 silicon germanium (SiGe) bipolar process. It features full-swing emitter coupled logic (ECL) output drivers capable of supporting PECL, NECL, and ECL configurations. The device provides two independent channels with a maximum toggle rate of 7.5 GHz and a typical propagation delay of 95 ps. It operates within a supply voltage range of 2.375 V to 3.63 V and includes on-chip 100 Ω center-tapped input terminations. The component is housed in a 16-lead LFCSP package and supports an extended industrial temperature range from -40°C to +125°C.

Clock Buffers, Drivers Feature Summary

• Ultrafast performance featuring 95 ps typical propagation delay and 60 fs random jitter
• Integrated 100 Ω differential on-chip input termination resistors
• Supports PECL, NECL, and standard ECL output configurations

Clock Buffers, Drivers Applications

• Clock and data signal restoration and level shifting
• Automated test equipment (ATE)
• High-speed instrumentation systems
• Converter clocking interfaces

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details. The R2 suffix indicates a tape and reel configuration. Ensure that the procurement source provides valid traceability for RoHS compliance as indicated by the Z suffix in the base model number. Cross-reference the part number with the latest datasheet revision to confirm pinout and electrical specifications remain unchanged.

Clock Buffers, Drivers Selection Notes

Select this component when dual-channel buffering with minimal added jitter is required for high-speed digital interfaces. The internal 100 Ω termination simplifies input matching for differential sources. Verify that the system power supply can maintain the required 2.375 V to 3.63 V range across the operating temperature extremes. Consider the thermal resistance of the 16-lead LFCSP package for adequate heat dissipation in dense PCB layouts.

Clock Buffers, Drivers Part Context

This device belongs to the ADCLK905/ADCLK907/ADCLK925 family of ultrafast SiGe buffers. While the ADCLK905 offers a single 1:1 channel and the ADCLK925 provides a 1:2 fanout, the ADCLK907 specifically delivers two isolated 1:1 channels. All variants share the same 16-lead LFCSP footprint and core SiGe technology, allowing for flexible design scaling based on channel count requirements.
