Overview
Description
The ADF7901BRUZ is a wideband RF frequency synthesizer (PLL) from Analog Devices. It provides a programmable fractional-N PLL used to generate stable local-oscillator or carrier frequencies for RF transceivers and front-ends.
Key points:
- Programmable fractional-N PLL with a reference divider and prescalers for flexible frequency synthesis.
- SPI-compatible control interface for setting frequency, modulation, and other options.
- Typically used for LO generation in receivers/transmitters, radar, wireless, and instrumentation applications.
- BRUZ denotes a RoHS-compliant 32-lead LFCSP package variant.
Why use it:
- High frequency resolution and fast frequency switching.
- Integrated AF/DF features (as supported by the device family) and compact packaging.
For exact specs (frequency range, phase noise, power, reference requirements, and pinout), refer to the ADF7901 data sheet and the BRUZ package documentation.
