ADF4382BCCZ

ADF4382BCCZ is Analog Devices’ high‑performance wideband fractional‑N/ integer‑N PLL frequency synthesizer. It generates RF outputs by using a reference clock and a programmable divider (with fractional-N capability) controlled via an SPI interface. Designed for broad RF/microwave use, it offers low phase noise and fast lock when used with an external reference and loop filter, covering a wide tuning range in wireless, radar, instrumentation, and test equipment. The BCCZ suffix indicates the commercial temperature grade with RoHS‑compliant packaging.

Direct pin-for-pin equivalents do not exist. Closest functional substitutes include:
- Analog Devices: ADF4350/4351 (fractional‑N synthesizers)
- Analog Devices: ADF4370/4372 family
- TI: LMX2571/LMX2574/LMX2581 (fractional‑N synthesizers)
Exact matching depends on frequency plan, VCO requirements, and package. Check datasheets or contact ADI/TI for a cross-reference.

Here are the typical features of the ADF4382BCCZ (Analog Devices) RF frequency synthesizer:
- Fractional-N PLL synthesizer for RF applications
- Supports integer and fractional-N operation with delta-sigma fractional modulation
- Wide tunable frequency range across the RF bands
- SPI-compatible serial control interface for register programming
- Programmable reference divider and modulus for fine frequency resolution
- On-chip phase detector and charge pump (external loop filter required)
- Low phase noise and low spurious performance
- Fast locking and deterministic settling
- Digital lock detect and programmable ramp/soft-start
- Power-down/standby mode for reduced power consumption
- Reference clock compatibility with standard sources (e.g., common 10–50 MHz ranges)
- Available in the BCCZ package (as noted in the part marking)
Note: For exact electrical specs, operating range, and application notes, refer to the official datasheet.

The ADF4382BCCZ is supplied in a 24‑lead LFCSP package (24 pins). It is a fully integrated fractional‑N PLL frequency synthesizer with an on‑chip VCO. Typical pin functions include:
- RF pins: VCO/RF output and RF feedback/matching pins
- Reference: REFIN and REFOUT/REFBUF
- Digital control: SDATA/SDI, SCLK, LE/LD (3‑wire serial interface)
- Power and ground: AVDD, DVDD, GND pins
- Control/bias: ENABLE/MUTE, bias and tuning pins, charge pump/phase‑detector nodes
For the complete pin‑by‑pin assignment, electrical characteristics and recommended PCB land pattern, consult the official ADF4382 datasheet.

The ADF4382BCCZ is manufactured by Analog Devices, Inc. (ADI). ADI is a multinational semiconductor company that designs and produces analog, mixed-signal and RF integrated circuits and signal‑processing solutions for industrial, communications, automotive and consumer markets.

Applications of ADF4382BCCZ:
- Wireless infrastructure: base stations, point-to-point/microwave backhaul
- Radar and sensing systems
- Satellite communications and transceivers
- Test and measurement equipment: signal generators, LO sources
- Clocking and timing references for telecom and data networks
(Uses a wideband, integrated VCO/PLL as LO and clock source.)

I don’t have live access to datasheets to verify ADF4382BCCZ’s package. Please upload the part’s datasheet or confirm whether you mean mechanical package (e.g., LFCSP, QFN). I can then extract the exact package type, dimensions, and pin count.
