Overview
The AD9522-1BCPZ-REEL7, produced by Analog Devices Inc., is a highly versatile clock generator designed for applications requiring precise clock distribution and generation. This component features a multioutput clock distribution function with subpicosecond jitter performance, making it ideal for high-speed and low-jitter clocking requirements. The AD9522-1 includes an on-chip PLL and VCO, which can tune from 2.27 GHz to 2.65 GHz, and also supports the use of an external 3.3 V/5 V VCO/VCXO up to 2.4 GHz.
The device is packaged in a 64-lead LFCSP (Lead Frame Chip Scale Package) and operates from a single 3.3 V supply, with the external VCO capable of operating up to 5.5 V. It is specified for operation over the standard industrial temperature range of −40°C to +85°C.
