ADCLK946BCPZ-REEL7

Clock Buffers, Drivers Overview

The ADCLK946BCPZ-REEL7 is a clock fanout buffer fabricated on Analog Devices' proprietary XFCB3 silicon germanium (SiGe) bipolar process. It features one differential input and six LVPECL outputs with a 1:6 distribution ratio. The device supports an operating frequency up to 4.8 GHz and accepts CML, CMOS, LVDS, and LVPECL inputs. Key electrical parameters include a maximum propagation delay of 220 ps, output-to-output skew of 28 ps, and broadband random jitter of 75 fs rms. It operates within a supply voltage range of 2.97 V to 3.63 V and functions across an industrial temperature range of -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Six full-swing LVPECL outputs for low jitter clock distribution
• Differential input with center-tapped 100 Ω on-chip termination resistors
• Supports multiple input formats including CML, CMOS, LVDS, and LVPECL
• Broadband random jitter specification of 75 fs rms

Clock Buffers, Drivers Applications

• Low jitter clock distribution systems
• Clock and data signal restoration
• Level translation between different logic families
• Wireless and wired communications infrastructure
• Medical and industrial imaging equipment
• ATE and high performance instrumentation

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to the Tape & Reel packaging format when sourcing components. Confirm that the RoHS compliant status aligns with current regulatory requirements for the intended deployment region. Ensure the supplier provides valid traceability documentation for the SiGe bipolar process technology used in manufacturing.

Clock Buffers, Drivers Selection Notes

Select this component for applications requiring ultrafast clock distribution with minimal added jitter. The internal 100 Ω differential termination simplifies interface design for CML and LVDS sources. Designers must ensure proper PCB layout techniques, including low impedance supply planes and adequate bypassing, to maintain specified performance characteristics at frequencies up to 4.8 GHz.

Clock Buffers, Drivers Part Context

This part belongs to the ADCLK946 series, which includes variants such as the ADCLK946BCPZ in tray packaging and the ADCLK946/PCBZ evaluation board. The REEL7 suffix specifically denotes the reel packaging option for automated assembly processes. All variants share identical electrical specifications and functional capabilities defined by the Rev B datasheet.

Clock Buffers, Drivers Replacement Considerations

Direct substitutes within the same family include the ADCLK946BCPZ, which offers identical electrical performance but utilizes tray packaging instead of tape and reel. No alternative cross-model replacements are documented in the provided source material.
