The XP devices are ultra-low phase noise quartz-based PLL oscillators supporting a large range of frequencies and output interface types. These devices are designed to operate at three different power supplies and are available in three package sizes with several pinout configurations, as well as three operational temperature ranges. The XP devices can be programmed to generate an output frequency from 15MHz to 2100MHz with a resolution as low as 1Hz accuracy. The configuration capability of this family of devices allows for fast delivery times for both sample and large production orders. Parts are for one time programming (OTP) at the factory for a fixed frequency application, or can be field programmable using I2C, based on system needs (see note 1 under Pin Descriptions)
