ADCLK914BCPZ-R7

Clock Buffers, Drivers Overview

The ADCLK914BCPZ-R7 is an ultrafast clock and data buffer fabricated on a silicon-germanium process. It features high voltage differential signaling (HVDS) outputs designed to drive high-speed digital-to-analog converters. The device operates at frequencies up to 7.5 GHz with a typical propagation delay of 160 ps and adds only 110 fs of random jitter. It accepts LVPECL, CML, CMOS, LVTTL, or AC-coupled LVDS inputs via on-chip 100 Ω terminations. Powered by a 3.3 V supply, it provides a differential output swing of approximately 1.95 V into 50 Ω loads. The component is housed in a 16-lead LFCSP package and supports operation from -40°C to +125°C.

Clock Buffers, Drivers Feature Summary

• Ultrafast SiGe performance with 7.5 GHz operating frequency and 160 ps propagation delay
• Low noise profile adding only 110 fs random jitter to the signal path
• HVDS output stage delivering ~1.95 V differential swing for direct DAC interfacing
• Integrated 100 Ω input termination supporting multiple logic families including LVPECL and CML

Clock Buffers, Drivers Applications

• Clock and data signal restoration in high-speed systems
• High-speed converter clocking for multi-GSPS DACs
• Broadband communications infrastructure
• Cellular base station architectures
• ATE and high-performance instrumentation

Clock Buffers, Drivers Procurement Notes

Verify that the ordering suffix R7 corresponds to the Tape & Reel packaging format as specified in the manufacturer's ordering guide. Confirm RoHS compliance status through official documentation. Ensure the procurement channel provides valid traceability for the Analog Devices Inc. manufacturing source. Check for any specific handling requirements related to the exposed pad thermal design.

Clock Buffers, Drivers Selection Notes

Select this component when driving high-speed DACs requiring high-amplitude, low-jitter clock signals. The HVDS output eliminates the need for external level shifters but requires careful impedance matching due to single-ended termination. Ensure the PCB layout minimizes parasitic inductance on power planes to maintain specified jitter performance. Verify that the input signal slew rate is sufficient to achieve the minimum random jitter specifications.

Clock Buffers, Drivers Part Context

This part belongs to the ADCLK914 series of ultrafast buffers. Other variants include the WP (Waffle Pack) and R2 (Reel) options, which share identical electrical characteristics but differ in shipping packaging. The device utilizes Analog Devices' proprietary XFCB-3 SiGe process to achieve its high-speed capabilities and low noise floor compared to standard bipolar technologies.

Clock Buffers, Drivers Replacement Considerations

Direct functional substitutes within the same family include ADCLK914BCPZ-WP and ADCLK914BCPZ-R2. These parts offer identical pinouts and specifications; the selection depends solely on preferred reel versus waffle pack packaging logistics.
