ADCLK925BCPZ-R7

Clock Buffers, Drivers Overview

The ADCLK925BCPZ-R7 is a 1:2 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, or CML configurations. The device provides a maximum toggle rate of 7.5 GHz and supports data rates up to 10 Gbps. Key electrical specifications include a typical propagation delay of 95 ps, a maximum of 125 ps, and 60 fs of random jitter. It operates within a supply voltage range of 2.375 V to 3.63 V and functions across an extended industrial temperature range from -40°C to +125°C.

Clock Buffers, Drivers Feature Summary

• Ultrafast SiGe performance with 7.5 GHz toggle rate and 10 Gbps data capability
• Low jitter characteristics featuring 60 fs random jitter and 95 ps typical propagation delay
• Integrated 100 Ω center-tapped input termination resistors for simplified interfacing
• Flexible ECL output stages designed to drive 800 mV into 50 Ω loads

Clock Buffers, Drivers Applications

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

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix R7 corresponds to the Tape & Reel packaging format as specified in the manufacturer's ordering guide. Confirm that the component meets RoHS compliance requirements indicated by the Z suffix in the base model designation. Ensure procurement channels provide valid traceability documentation for the specific manufacturing lot.

Clock Buffers, Drivers Selection Notes

Select this component when a single-ended differential input must be fanned out to two independent ECL-compatible destinations. The internal 100 Ω input termination simplifies source matching requirements. Verify that the application environment remains within the -40°C to +125°C operating temperature range to maintain specified AC performance parameters.

Clock Buffers, Drivers Part Context

This part belongs to the ADCLK905/ADCLK907/ADCLK925 family of ultrafast buffers. While the ADCLK905 offers a 1:1 ratio and the ADCLK907 provides dual 1:1 channels, the ADCLK925 specifically delivers one input to two outputs. All variants share identical pinouts and package dimensions in the 16-lead LFCSP form factor.

Clock Buffers, Drivers Replacement Considerations

The ADCLK925BCPZ-WP serves as the waffle pack alternative to the R7 reel variant. Both parts share identical electrical specifications and functionality; the distinction lies solely in the shipping packaging configuration.
