Asahi Kasei Microdevices AK1546

The AK1546 is an Integer-N PLL (Phase Locked Loop) frequency synthesizer, covering a wide range of frequency from 500MHz to 3GHz. The operating supply voltage is from 2.7V to 3.3V, and the charge pump circuit and the serial interface can be driven by individual supply voltage. An ideal PLL can be achieved by combining the AK1546 with the external loop filter and VCO (Voltage Controlled Oscillator).
