ADCLK846BCPZ-REEL7

Clock Buffers, Drivers Overview

The ADCLK846BCPZ-REEL7 is a low power clock fanout buffer from Analog Devices, housed in a 24-LFCSP package. It operates on a single 1.8 V supply (1.71 V to 1.89 V) and supports input frequencies up to 1.2 GHz. The device provides selectable LVDS or CMOS outputs, configurable via CTRL_A and CTRL_B pins. It delivers up to 6 LVDS outputs at 1.2 GHz or 12 CMOS outputs at 250 MHz. Key electrical parameters include a propagation delay of 2.0 ns for LVDS and 3.2 ns for CMOS, with integrated jitter of 54 fs rms (12 kHz to 20 MHz).

Clock Buffers, Drivers Feature Summary

• Configurable output logic: Selectable between 6 LVDS outputs (up to 1.2 GHz) and 12 CMOS outputs (up to 250 MHz) using pin-programmable control.
• Low jitter performance: Features 54 fs rms integrated random jitter (12 kHz to 20 MHz) and 100 fs additive broadband jitter.
• Flexible input compatibility: Accepts differential or single-ended inputs including LVPECL, LVDS, HSTL, CML, and CMOS levels.
• Power management: Includes a sleep mode to power down the device, reducing current consumption to 3 mA.

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

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to the Tape & Reel packaging format when sourcing. Confirm that the component meets RoHS compliance requirements for the intended application environment. Ensure the supplier provides valid traceability documentation for the Analog Devices Inc. manufacturer part number.

Clock Buffers, Drivers Selection Notes

Select this component when a 1.8 V supply voltage is available and mixed LVDS/CMOS output configurations are required. Evaluate the input slew rate requirements, as jitter performance degrades with lower slew rates below 1 V/ns. Consider the thermal resistance characteristics of the LFCSP package if operating near the upper temperature limit of +85°C.

Clock Buffers, Drivers Part Context

This part belongs to the ADCLK846 series of clock buffers. The BCPZ designation indicates the commercial temperature range (-40°C to +85°C) and the LFCSP-24 package type. The REEL7 suffix specifies the reel packaging quantity and style used for automated surface-mount assembly processes.

Clock Buffers, Drivers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pin compatibility and electrical specifications against alternative clock buffers if direct replacement is necessary.
