AK1544
1300MHz Integer-N Frequency Synthesizer
1. Overview
Consisting a highly accurate charge pump that supports current adjustment in 9 steps, a reference divider, a programmable divider and a dual-modulus prescaler (P/P+1), the AK1544 provides high performance, low consumption current and small footprint for a wide range of frequency conversions. This synthesizer also has two general-purpose output pins which allow it to be used to control the RF front end. An ideal Phase Locked Loop (PLL) can be achieved by combining the AK1544 with the external loop filter and VCO (Voltage Controlled Oscillator). Access to the registers is controlled via a 3-wire serial interface. The operating supply voltage is from 2.7V to 5.
