Analog Devices AD9520-5 Clock Generator Datasheet
The AD9520-5 provides a multi‑output clock distribution function with sub‑picosecond jitter performance. It supports external VCO/VCXO up to 2.4 GHz, offers twelve LVPECL outputs (grouped in four sets) that can be reconfigured as CMOS outputs, and includes programmable dividers, zero‑delay operation and automatic reference switchover.
The device is controlled via an SPI‑ or I²C‑compatible serial port and stores configuration settings in an on‑package EEPROM. It operates from a single 3.3 V supply over the industrial temperature range (‑40 °C to +85 °C) and is supplied in a 64‑lead LFCSP package.
