Product Introduction

Overview

The AD9528BCPZ, produced by Analog Devices Inc., is a highly advanced clock generator designed to meet the stringent requirements of modern high-speed data conversion and communication systems. This component features a two-stage phase-locked loop (PLL) architecture, which includes an integrated JESD204B/JESD204C SYSREF generator. The first stage PLL (PLL1) conditions the input reference clock to reduce jitter, while the second stage PLL (PLL2) generates high-frequency clocks with low integrated jitter and broadband noise. The on-chip voltage-controlled oscillator (VCO) tunes from 3.450 GHz to 4.025 GHz, and the SYSREF generator outputs signals to time-align multiple devices.

  • ATE and high-performance instrumentation.

Q & A

  1. What is the primary function of the AD9528BCPZ?

    The AD9528BCPZ is a clock generator with a two-stage PLL and an integrated JESD204B/JESD204C SYSREF generator, designed for multiple device synchronization and low jitter clock distribution.

  2. What are the key components of the AD9528BCPZ's PLL architecture?

    The AD9528BCPZ features two PLL stages: PLL1 for input reference conditioning and PLL2 for high-frequency clock generation.

  3. What is the frequency range of the on-chip VCO?

    The on-chip VCO tunes from 3.450 GHz to 4.025 GHz.

  4. How many output channels does the AD9528BCPZ have, and what are their maximum frequencies?

    The AD9528BCPZ has 14 output channels, with six outputs (OUT0 to OUT3, OUT12, OUT13) capable of up to 1.25 GHz and eight outputs capable of up to 1 GHz.

  5. What is the purpose of the SYSREF generator in the AD9528BCPZ?

    The SYSREF generator outputs single shot, N-shot, or continuous signals synchronous to the PLL outputs to time-align multiple devices.

  6. Can the AD9528BCPZ be used as a flexible buffer?

    Yes, the AD9528BCPZ can be used as a dual input flexible buffer to distribute 14 device clock and/or SYSREF signals.

  7. What are some typical applications of the AD9528BCPZ?

    Typical applications include LTE and multicarrier GSM base stations, wireless and broadband infrastructure, medical instrumentation, and high-speed data acquisition systems.

  8. How does the AD9528BCPZ ensure timing alignment across its output channels?
