ADCLK954BCPZ

Clock Buffers, Drivers Overview

The ADCLK954BCPZ is a high-speed clock fanout buffer fabricated on Analog Devices' proprietary SiGe bipolar process. It features two selectable differential inputs and twelve LVPECL outputs, supporting operating frequencies up to 4.8 GHz. The device exhibits a broadband random jitter of 75 fs rms and a maximum propagation delay of 245 ps. It operates on a single 3.3 V supply (2.97 V to 3.63 V) within the industrial temperature range of -40°C to +85°C. Packaged in a 40-lead LFCSP (CP-40-16), it includes on-chip input terminations for simplified design.

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation. The BCPZ designation indicates RoHS compliance and the standard industrial temperature range. Confirm package details match the CP-40-16 option. Cross-reference with official distributor listings to ensure availability status aligns with current production cycles.

Clock Buffers, Drivers Selection Notes

Select this component for applications requiring low jitter distribution from a single source to multiple destinations. Ensure the input signal slew rate exceeds 4 V/ns to maintain optimal jitter performance. Verify that the receiving buffers are compatible with LVPECL logic levels terminated to VCC minus 2 V. Consider thermal management requirements due to the exposed paddle connection to the VEE plane.

Clock Buffers, Drivers Part Context

This part belongs to the ADCLK954 series of ultrafast clock buffers. It is designed for high-speed applications where signal integrity and timing precision are critical. The SiGe technology enables operation at frequencies significantly higher than standard CMOS counterparts while maintaining low power consumption relative to performance.

Clock Buffers, Drivers Replacement Considerations

The ADCLK954BCPZ-REEL7 is the reel-packaged version of the same functional device. No direct cross-brand replacements are confirmed in public documentation. Evaluate alternative SiGe or BiCMOS fanout buffers if form factor or pinout constraints require changes.
