The ANFNPLL0100 is a fractional-N frequency synthesizer that can be used to implement local oscillator (LO) in the low power, low data rate, wireless applications such as ZigBee, Bluetooth Low Energy (LE). The frequency synthesizer consists of low noise phase frequency detector (PFD), a precision
charge pump, an internal loop filter, and dual band voltage controlled oscillator (VCO). The frequency synthesizer has 5-bit programmable divider
supporting integer multiplication up to 63, and 3rd order sigma-delta modulator supporting 20-bit fractional resolution.
