Overview
The AD9520-1BCPZ-REEL7, produced by Analog Devices Inc., is a highly advanced clock generator and distribution device. It features a multi-output clock distribution function with sub-picosecond jitter performance, making it ideal for applications requiring precise and stable clock signals. The device includes an on-chip PLL (Phase-Locked Loop) and a VCO (Voltage-Controlled Oscillator) that tunes from 2.27 GHz to 2.65 GHz. Additionally, it supports the use of an external 3.3 V/5 V VCO/VCXO up to 2.4 GHz.
The AD9520-1BCPZ-REEL7 is designed to operate from a single 3.3 V supply, with the option for a separate output driver power supply ranging from 2.375 V to 3.465 V. It is packaged in a 64-lead LFCSP (Lead Frame Chip Scale Package) and is specified for operation over the standard industrial temperature range of −40°C to +85°C.
