The ADF4007BCPZ is a high Frequency Divider/PLL Synthesizer that can be used in a variety of communications applications. It can operate to 7.5GHz on the RF side and to 120MHz at the PFD. It consists of a low noise digital PFD (phase frequency detector), a precision charge pump and a divider/prescaler. The divider/prescaler value can be set by two external control pins to one of four values (8, 16, 32 or 64). The reference divider is permanently set to 2, allowing an external REFIN frequency of up to 240MHz. A complete PLL (phase-locked loop) can be implemented if the synthesizer is used with an external loop filter and a VCO (voltage controlled oscillator). Its very high bandwidth means that frequency doublers can be eliminated in many high frequency systems, simplifying system architecture and reducing cost.
- Separate charge pump supply (VP) allows extended tuning voltage in 3V systems
- RSET control of charge pump current
- Hardware power-down mode
