Description

The AK1542A is a 20MHz to 600MHz band Phase Locked Loop frequency synthesizer with frequency switching function using Integer-N.
The AK1542A consists of a low-noise phase frequency comparator, a charge pump with high accuracy and 9-stage current adjustment, a reference divider, a programmable divider and a dual modulus prescaler (P / P + 1). High performance, low current consumption, and miniaturization are realized in various frequency conversion situations. In addition, two general-purpose output terminals are available and can be used for RF front-end control.
The AK1542A can be combined with an external loop filter and VCO (Voltage Contlled Oscillator) to form a complete Phase Locked Loop. Access to the AK1542A registers is controlled by a 3 wire serial interface. The power supply voltage operates from 2.7V to 5.5V, and the power supply system of the charge pump circuit and serial interface can be driven independently.

Key Features
