ADCLK944BCPZ-WP

Clock Buffers, Drivers Overview

The ADCLK944BCPZ-WP is a high-speed clock fanout buffer fabricated on Analog Devices' proprietary XFCB3 silicon germanium (SiGe) bipolar process. It features one differential input and four LVPECL outputs, operating at frequencies up to 7.0 GHz with a broadband random jitter of 50 fs rms. The device includes on-chip 100 Ω differential input termination resistors and accepts various input formats including LVPECL, CML, LVDS, and CMOS. Powered by a supply voltage between 2.375 V and 3.63 V, it operates within an industrial temperature range of -40°C to +85°C and is housed in a 16-lead LFCSP package.

Clock Buffers, Drivers Feature Summary

• Broadband random jitter of 50 fs rms
• On-chip center-tapped 100 Ω differential input termination
• Supports DC-coupled LVPECL, CML, and AC-coupled LVDS/CMOS inputs

Clock Buffers, Drivers Applications

• Low jitter clock distribution
• Clock and data signal restoration
• Level translation
• Wireless communications
• Medical and industrial imaging

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix WP against official documentation to confirm packaging details, as suffixes may indicate variations in reel or tray configuration without altering electrical function. Ensure compatibility with standard industrial temperature ranges (-40°C to +85°C) for the target application environment.

Clock Buffers, Drivers Selection Notes

Select this component when low added jitter and high-speed fan-out are required for LVPECL systems. The integrated input termination simplifies design by eliminating external resistors. Ensure the input slew rate exceeds 1 V/ns to maintain optimal jitter performance, and verify that the power supply voltage remains within the 2.375 V to 3.63 V range.

Clock Buffers, Drivers Part Context

This part belongs to the ADCLK944 series of SiGe clock buffers. It is distinct from evaluation kits like the ADCLK944/PCBZ and other packaging variants such as the tape-and-reel versions (R2/R7). The WP suffix denotes a specific bulk or waffle pack configuration for the 16-lead LFCSP_WQ package.
