Overview
The AD9571ACPZLVD-R7, produced by Analog Devices Inc., is a multioutput clock generator optimized for Ethernet line card applications. It features a dedicated PLL core based on Analog Devices' proven portfolio of high-performance, low-jitter frequency synthesizers. This component is designed to maximize network performance and is suitable for applications with demanding phase noise and jitter requirements.
The AD9571 integrates a low noise phase frequency detector (PFD), a precision charge pump (CP), a low phase noise voltage controlled oscillator (VCO), and preprogrammed feedback and output dividers. It operates from a single 3.3 V supply and is available in a 40-lead 6 mm × 6 mm lead frame chip scale package (LFCSP). The operating temperature range is −40°C to +85°C.
