概述
Description
The AD9522-3BCPZ is a high-performance clock generator and jitter cleaner from Analog Devices. It provides low-phase-noise clock distribution with 12 outputs, supporting frequencies up to 1.25 GHz (LVDS) or 250 MHz (LVPECL/CMOS).
Key features:
- Inputs: Accepts LVDS, LVPECL, or CMOS references.
- PLL: Dual PLL architecture with an integrated VCO (1.45–1.8 GHz) and optional external VCXO for lower jitter.
- Outputs: 12 configurable outputs (6 LVDS, 6 LVPECL/CMOS) with independent dividers.
- Jitter Cleaner: Reduces input clock jitter (<1 ps RMS).
- Applications: Ideal for high-speed data converters, wireless infrastructure, and FPGA clocking.
The device operates from a 3.3 V supply and comes in a 32-lead LFCSP (5x5 mm) package. It offers SPI-programmable flexibility for precise timing solutions.
For detailed specs, refer to the [AD9522 datasheet](https://www.analog.com/media/en/technical-documentation/data-sheets/AD9522.pdf).
