ADCLK950BCPZ-REEL7

Clock Buffers, Drivers Overview

The ADCLK950BCPZ-REEL7 is a high-performance clock fanout buffer fabricated on Analog Devices' proprietary SiGe bipolar process. It features two selectable differential inputs and ten LVPECL outputs, operating at frequencies up to 4.8 GHz. The device accepts various input formats including CML, CMOS, LVDS, and LVPECL via internal 100 Ω termination resistors. Powered by a 3.3 V supply (2.97 V to 3.63 V), it delivers low jitter performance with 75 fs rms broadband random jitter. Packaged in a 40-lead LFCSP (CP-40-16), it supports operation from -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Two selectable differential inputs with integrated 100 Ω center-tapped termination resistors

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix REEL7 corresponds to the tape and reel packaging format as specified in the manufacturer's ordering guide. Confirm that the component meets RoHS compliance standards indicated by the Z suffix in the base part number. Ensure procurement channels provide valid traceability documentation for the Analog Devices Inc. manufactured silicon germanium process device.

Clock Buffers, Drivers Selection Notes

Select this component when designing systems requiring low jitter clock distribution with multiple outputs. Ensure the input signal slew rate exceeds 4 V/ns to maintain optimal jitter performance. Verify that the PCB layout supports the required 50 Ω impedance matching for both input and output transmission lines. Confirm power supply decoupling strategies meet the thermal and electrical requirements for the 40-LFCSP package.

Clock Buffers, Drivers Part Context

This part belongs to the ADCLK950 series of clock buffers. It is functionally identical to the ADCLK950BCPZ but supplied in a reel format rather than tube packaging. The evaluation board ADCLK950/PCBZ is available for testing circuit performance and layout verification during the design phase.

Clock Buffers, Drivers Replacement Considerations

The ADCLK950BCPZ serves as the tube-packaged equivalent of this reel-supplied component. No other functional substitutes are confirmed in the provided documentation.
