ADF4350BCPZ-RL

The ADF4350BCPZ-RL is Analog Devices’ wideband, programmable PLL frequency synthesizer with an integrated voltage-controlled oscillator (VCO). It is designed to generate precise RF local-oscillator (LO) signals for RF transceivers and up/down converters.
Key points:
- Integrated VCO and phase-locked loop with fractional-N division for fine frequency steps.
- RF outputs: typically 50-ohm, with configurable output power on RFOUT0/RFOUT1.
- Reference input: accepts a reference clock (e.g., 10–50 MHz) with a programmable reference divider.
- Programmable via SPI: set integer and fractional components (N, MOD, etc.) to synthesize the desired RF frequency.
- Features: lock detect, power-down, mute, calibration, multiple reference/divider options.
- Package and form: BCPZ package; RL suffix indicates tape-and-reel shipping.
- Applications: LO generation for radios, transceivers, test equipment, and other wideband synthesis needs.
Note: Always consult the datasheet for exact pinout, electrical specs, and recommended application circuits for your target frequency.
