AK1573/B/C数据手册AKM中文资料规格书

描述 Description

AK1573 is the Integer-N frequency synthesizer with integrated VCO (Voltage Controlled Oscillator). It is composed of programmable charge pump, reference divider, programmable divider, dual modulus prescaler (P / P + 1). With the feature of high-performance, low noise and small size, it can be used as a local signal source of a variety of frequency conversion.By combining with an external loop filter, AK1573 form a complete Phase Locked Loop.Access to the register is controlled by the serial interface of the 3-wire and Power supply voltage is 2.7V to 3.3V.
