ADCLK914BCPZ-R2

Clock Buffers, Drivers Overview

The ADCLK914BCPZ-R2 is an ultrafast, silicon-germanium (SiGe) clock and data buffer featuring a single differential open-collector output. It operates at frequencies up to 7.5 GHz with a maximum propagation delay of 202 ps and adds only 110 fs of random jitter. The device accepts LVPECL, CML, CMOS, LVTTL, or AC-coupled LVDS inputs via on-chip 100 Ω terminations. Its HVDS output stage provides a total differential swing of 3.8 V into 50 Ω loads. Powered by a 3.3 V supply (VCC − VEE), it functions within an extended industrial temperature range of −40°C to +125°C in a 16-lead LFCSP package.

Clock Buffers, Drivers Procurement Notes

Verify that the ordering suffix -R2 corresponds to the Tape & Reel packaging option as specified in the manufacturer's ordering guide. Confirm RoHS compliance status through official documentation. Ensure procurement channels provide valid traceability for the Analog Devices Inc. component. Check for any specific handling requirements related to the moisture sensitivity level indicated in the datasheet.

Clock Buffers, Drivers Selection Notes

Select this buffer when driving high-speed DACs requiring high-amplitude, low-jitter clocks. The internal 100 Ω input termination simplifies interface design for standard logic families. Ensure the application layout minimizes parasitic inductance on power planes to maintain specified jitter performance. Verify that the 3.3 V supply voltage aligns with system power rails and that thermal management supports the junction temperature limits.

Clock Buffers, Drivers Part Context

This component belongs to the ADCLK914 series of ultrafast SiGe buffers. It is functionally identical to the ADCLK914BCPZ-WP and ADCLK914BCPZ-R7 variants, differing only in the shipping packaging format. The device utilizes Analog Devices' proprietary XFCB-3 complementary bipolar process to achieve its high-speed specifications.
