Features: When the supply voltage is 3V, the power consumption of only 20mW, very suitable for power sensitive applications. Frequency register 28bit; clock rate of 75MHz, can achieve a resolution of 0.28 Hz. Affect the frequency and phase modulation method is through the serial interface to load the register, then register by software or FSELECT / PSELECT pin switches Device. The serial interface that operates at clock rates up to 40MHz and is compatible with digital signal processing and micro-controller standards. The device is 2.3V to 5.5V power supply. Analog and digital sections are independent, you can use different power supply; for example, AVDD can be 5V, and DVDD can be 3V. No part of the device may shut off to minimize power consumption. For example, when generating a clock output can be turned off DAC. The device uses a 20-pin TSSOP package. liquid and air flow measurement, sensor applications, proximity, motion and defect detection, testing and medical equipment.
