Analog Devices Inc. LTC6948IUFD-3 is a fractional-N clock/frequency synthesizer designed for high-performance RF and IF applications. This single-chip solution integrates a low-noise Phase-Locked Loop (PLL) with a voltage-controlled oscillator (VCO) to deliver precise frequency synthesis up to 5.79GHz. The device features a fractional-N architecture, enabling fine frequency resolution without compromising phase noise. It accepts a clock input and provides a clock output, with differential input and output capabilities for enhanced signal integrity. The LTC6948IUFD-3 includes internal dividers and operates within a voltage range of 3.15V to 5.25V. Packaged in a 28-lead 4x5mm QFN with an exposed pad for optimal thermal management, it is suitable for surface mounting. This component finds extensive use in wireless infrastructure, test and measurement equipment, and radar systems. Operating temperature range is -40°C to 105°C.
