The AD9522-2 is a clock generator from Analog Devices that provides 12 LVDS and 24 CMOS outputs. It has low phase noise, frequency synthesis, and more.
The AD9522-2 provides twelve 800 MHz LVDS outputs (each can be re‑configured as two 250 MHz CMOS outputs) and supports a wide range of reference inputs, including differential, single‑ended CMOS, LVPECL and LVDS. It features an on‑chip VCO that can be tuned from 2.02 GHz to 2.335 GHz, as well as optional external VCO/VCXO operation up to 2.4 GHz.
The device includes both SPI and I²C serial control ports, a 64‑lead LFCSP package, and operates from a single 3.3 V supply (3.135‑3.465 V typical). It is specified for industrial temperature range (‑40 °C to +85 °C) and offers low jitter, low phase‑noise performance suitable for high‑speed data‑converter and communication applications.
