The LMX2485Q-Q1 is a low power, high-performance delta-sigma fractional-N phase-locked loop (PLL) designed for automotive applications, specifically in RF personal communications. It features an auxiliary integer-N PLL and operates within a frequency range of 500 MHz to 3.1 GHz. The device utilizes advanced delta-sigma architecture to minimize fractional spurs and phase noise, making it suitable for direct digital modulation applications. The LMX2485Q-Q1 supports a programmable delta-sigma modulator with up to fourth-order capability, allowing designers to optimize performance based on specific system requirements. It includes a high-speed MICROWIRE interface for programming, enabling fast frequency changes with low spurs and fine frequency resolution. The device is housed in a compact 24-lead WQFN package, measuring 4.0 mm x 4.0 mm, and is AEC-Q100 Grade 2 qualified, ensuring reliability in automotive environments. Additional features include digital lock detect output, hardware and software power-down control, and an integrated input frequency doubler. The LMX2485Q-Q1 operates with a supply voltage range of 2.5 V to 3.6 V and has a low current consumption of 5.0 mA, making it an efficient choice for automotive RF applications.
