ADF4007

High Frequency Divider/PLL Synthesizer

Manufactured by:

Product Details

The ADF4007 is a high frequency divider/PLL synthesizer that can be used in a variety of communications applications. It can operate to 7.5 GHz on the RF side and to 120 MHz at the PFD. It consists of a low noise digital PFD (phase frequency detec-tor), 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 240 MHz.

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.

Applications

  • Satellite communications
  • Broadband wireless access
  • CATV
  • Instrumentation
  • Wireless LANs
