ADF4002SRU-EP-RL7

锁相环 - PLL Phase Detect / PLL Freq Synthesizer

Product Details

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 programmable N divider. The 14-bit reference counter R counter, allows selectable REFIN frequencies at the PFD input.

A complete phase-locked loop PLL can be implemented if the synthesizer is used with an external loop filter and voltage controlled oscillator VCO. In addition, by programming R and N to 1, the device can be used as a standalone PFD and charge pump.

The ADF4002-EP supports defense and aerospace applications AQEC standard.
