AD9543BCPZ

Overview

The AD9543BCPZ is a quad-input, 10-output clock synchronizer and jitter cleaner manufactured by Analog Devices Inc. It features two digital phase-locked loops (DPLLs) capable of synchronizing physical layer clocks from 2 kHz to 750 MHz with frequency translation and jitter cleaning. The device supports IEEE 1588 Version 2 and Synchronous Ethernet applications through two programmable auxiliary NCOs. It operates on a single 1.8 V supply within the -40°C to +85°C temperature range and is housed in a 48-lead LFCSP package.

Feature Summary

• Dual DPLL architecture for high-performance synchronous clocking and jitter cleaning
• Supports ITU-T G.8262, Telcordia GR-253, and IEEE 1588 standards
• Two independent auxiliary NCOs with resolution < 1.4 × 10⁻¹² Hz
• Programmable reference switching with automatic/manual holdover

Applications

• PTP (IEEE 1588) and SyncE jitter cleanup and synchronization
• Optical transport networks (OTN), SDH, and macro/small cell base stations
• Stratum 2, Stratum 3e, and Stratum 3 holdover systems
• JESD204B support for ADC and DAC clocking

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure proper ESD handling procedures are followed during storage and installation to maintain device integrity.

Selection Notes

Select this component for applications requiring precise frequency translation and low-jitter output generation from noisy references. Consider the 48-lead LFCSP package constraints and thermal dissipation requirements when designing the PCB layout. Verify that the input reference frequencies fall within the supported ranges for optimal performance.

Part Context

The AD9543 belongs to the AD9543 series of clock synchronizers designed for carrier-grade networking equipment. It serves as a derivative solution for baseband unit (BBU) clocking in wireless infrastructure, offering robust synchronization capabilities compared to standard clock generators.
