概述

Description

AD9542BCPZ is Analog Devices’ dual-output, high-performance clock generation and jitter-cleaning IC. It is designed to provide low-jitter, synchronized clocks for multi-channel ADC/DAC front-ends, SERDES, and RF transceivers, with flexible clock distribution. Key features include two PLLs with a fractional-N synthesizer, a jitter-cleaning path, programmable output dividers, and multiple differential outputs (LVDS/LVPECL/CMOS with selectable drive). It also supports JESD204B/C SYSREF for deterministic latency and multi-device synchronization. The part accepts a reference input from external sources, with options for reference bypass and configurable output timing. Packaging: 32-lead LFCSP in the BCPZ variant. Common applications: clock distribution for high-speed data converters, RF/communications systems, and high-speed SERDES interfaces in test equipment and instrumentation.

Package

AD9542BCPZ is in a 28-lead LFCSP (Lead Frame Chip Scale Package), RoHS-compliant.

Pinout

- Pin count: 28-pin LFCSP (package code BCPZ).
- Function: Dual low-jitter clock generator / jitter cleaner (PLL) used to generate and distribute clean system clocks and references for JESD204B/C interfaces.

Manufacturer

Analog Devices, Inc. (ADI). It is an American multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing (DSP) integrated circuits.

Application

AD9542BCPZ is a dual jitter-cleaning clock multiplier/PLL used to generate clean, low-jitter reference clocks for high-speed converters. Typical applications:
- RF/microwave transceivers and radar
- Wireless base stations
- JESD204B/C data-converter clocking and synchronization
- High-speed test and measurement equipment
- Optical communications transceivers
- Multi-channel data acquisition systems needing low-skew, synchronized clocks
- Clock distribution in multi-board systems
