AD9514BCPZ

Clock Buffers, Drivers Overview

The AD9514BCPZ is a multi-output clock distribution integrated circuit from Analog Devices, designed for low jitter and phase noise applications. It features a differential clock input supporting frequencies up to 1.6 GHz. The device provides three independent outputs: two LVPECL outputs operating up to 1.6 GHz and one configurable output supporting LVDS (up to 800 MHz) or CMOS (up to 250 MHz). Each output includes a programmable divider with a range of 1 to 32. The component operates on a single 3.3 V supply within an industrial temperature range of -40°C to +85°C and is housed in a 32-lead LFCSP package.

Clock Buffers, Drivers Feature Summary

• Three independent clock outputs: two LVPECL (1.6 GHz max) and one LVDS/CMOS (800 MHz/250 MHz max)
• Programmable dividers for each output with integer division ratios from 1 to 32
• Additive broadband output jitter of 225 fs rms for LVPECL and 300 fs rms for LVDS modes
• Hardware configuration via 11 logic pins (S0–S10) without requiring an external controller

Clock Buffers, Drivers Applications

• Clocking high-speed ADCs, DACs, DDSs, DDCs, and DUCs
• Low jitter, low phase noise clock distribution systems
• High-performance wireless transceivers
• Broadband infrastructure equipment

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation. Suffixes such as REEL7 indicate tape-and-reel packaging, while other suffixes may denote tray packaging. Confirm that the selected variant matches the required physical package and shipping format for the intended manufacturing process.

Clock Buffers, Drivers Selection Notes

Select this component when subpicosecond jitter performance is critical for data converter applications. Ensure the design accommodates the 3.3 V supply voltage and the 32-lead LFCSP footprint. Verify that the required output logic levels (LVPECL, LVDS, or CMOS) align with the system interface requirements and that the input clock slew rate meets the 1 V/ns specification.
