Frequency Synthesizer with Integrated VCO

MP

Description

The AK1573B is an integer N type frequency synthesizer with a built-in VCO (Voltage Controlled Oscillator 2600MHz). 
It consists of an eight-stage current-adjustable charge pump, reference divider, programmable divider, dual modulus prescaler (P / P + 1), and low phase noise VCO. 
The AK1573B realizes a complete Phase Locked Loop when combined with an external loop filter.
The AK1573B features low current consumption and low noise, and because of its small package, it can be expected to reduce the size of equipment.

Key Features

  • Low current consumption. / Low noise.
