The ADF4002 frequency synthesizer is used to implement local oscillators in the up-conversion and down-conversion sections of wireless receivers and transmitters. It consists of a low noise digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider and a programmable N divider. The 14-bit reference divider (R divider) allows the REFIN frequency at the PFD input to be selectable.
If the frequency synthesizer is used with an external loop filter and a voltage controlled oscillator (VCO), a complete phase-locked loop (PLL) can be implemented. In addition, if R and N are programmed to 1, the device can be used as a standalone PFD and charge pump.
The ADF4002-EP supports defense and aerospace applications (AQEC standard). Shielding shell and anti-reverse protection diode.
