ADCLK925BCPZ-R2

Clock Buffers, Drivers Overview

The ADCLK925BCPZ-R2 is a 1:2 ECL clock and data fanout buffer fabricated on Analog Devices' proprietary XFCB3 silicon germanium (SiGe) bipolar process. It features full-swing emitter coupled logic output drivers capable of operating in PECL or NECL configurations. The device provides a typical propagation delay of 95 ps, a toggle rate up to 7.5 GHz, and 60 fs random jitter. It includes on-chip 100 Ω center-tapped input terminations and operates within a supply voltage range of 2.375 V to 3.63 V across an extended industrial temperature range of −40°C to +125°C.

Clock Buffers, Drivers Feature Summary

• Ultrafast SiGe performance with 7.5 GHz toggle rate and 95 ps typical propagation delay
• Low random jitter specification of 60 fs rms
• Integrated 100 Ω differential input termination resistors
• Supports PECL and NECL output configurations

Clock Buffers, Drivers Applications

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

Clock Buffers, Drivers Procurement Notes

Verify the package option CP-16-27 corresponds to the 16-Lead Lead Frame Chip Scale Package. Confirm RoHS compliance status indicated by the Z suffix. Ensure the R2 suffix matches the required tape and reel packaging format for surface mount assembly processes.

Clock Buffers, Drivers Selection Notes

Select this component when a single-ended differential input must be fanned out to two independent ECL-compatible loads. Verify that the system power supply allows for the required VCC minus VEE differential voltage between 2.375 V and 3.63 V. Ensure layout supports high-speed transmission line matching for the specified output swing.

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 integrates one input driving two outputs within a single 16-lead LFCSP package.
