AD9528BCPZ

Overview

The AD9528BCPZ is a dual-stage phase-locked loop (PLL) clock generator with an integrated JESD204B/JESD204C SYSREF generator, designed for multi-device synchronization. It features 14 LVDS/HSTL outputs, with six channels supporting frequencies up to 1.25 GHz and eight channels up to 1 GHz. The device includes a two-stage PLL architecture where the first stage cleans reference jitter using an external VCXO, and the second stage utilizes an on-chip VCO tuned from 3.450 GHz to 4.025 GHz. Supply voltage ranges from 3.135 V to 3.465 V, with maximum supply current reaching 71 mA.

Feature Summary

• Dual-stage PLL architecture with integrated low-noise VCO (3.450 GHz to 4.025 GHz)
• 14 configurable LVDS/HSTL outputs; six outputs reach 1.25 GHz, eight reach 1 GHz
• Integrated JESD204B/JESD204C SYSREF generator for single-shot, N-shot, or continuous signals
• Per-output digital coarse delay (63 steps) and analog fine delay (15 steps of 31 ps resolution)

Applications

• High performance wireless transceivers
• LTE and multicarrier GSM base stations
• Clocking high speed ADCs, DACs, DDSs, DDCs, DUCs, MxFEs
• ATE and high performance instrumentation

Procurement Notes

Verify that the component matches the exact part number AD9528BCPZ. Confirm the package type is LFCSP with 72 pins. Ensure the operating temperature range meets requirements of -40°C to +85°C. Check serial control port compatibility for SPI or I2C interfaces as needed for system integration.

Selection Notes

Select this component when precise timing alignment across multiple devices is required. The dual PLL structure allows for low jitter performance by utilizing an external VCXO for the first stage. Ensure the application supports the required supply voltage range of 3.135 V to 3.465 V and accommodates the maximum power dissipation specifications under full load conditions.
