The product is a 12-channel LVDS/24-channel CMOS output clock generator with an integrated 2.4 GHz VCO, low phase noise, phase-locked loop (PLL).
The AD9522-1 provides a multi‑output clock distribution function with twelve LVDS outputs (24 CMOS) and an on‑chip VCO that tunes from 2.27 GHz to 2.65 GHz. It supports both SPI and I²C serial control, includes an EEPROM for configuration storage, and operates from a single 3.3 V supply (up to 5.25 V on VCP).\n\nDesigned for low‑jitter, low‑phase‑noise applications, the device can be used for clock generation and translation in high‑speed data interfaces, ADC/DAC clocking, wireless transceivers, and test equipment. Various operation modes allow internal VCO use, external VCO/VCXO integration, and zero‑delay synchronization.
