Product Details
The ADF4355 allows implementation of fractional-N or integer-N phase-locked loop (PLL) frequency synthesizers when used with an external loop filter and an external reference frequency. A series of frequency dividers permits operation from 54 MHz to 6800 MHz.
The ADF4355 has an integrated VCO with a fundamental output frequency ranging from 3400 MHz to 6800 MHz. In addition, the VCO frequency is connected to divide by 1, 2, 4, 8, 16, 32, or 64 circuits that allow the user to generate radio frequency (RF) output frequencies as low as 54 MHz. For applications that require isolation, the RF output stage can be muted. The mute function is both pin and software controllable.
Control of all on-chip registers is through a simple 3-wire interface. The ADF4355 operates with analog and digital power supplies ranging from 3.15 V to 3.45 V, with charge pump and VCO supplies from 4.75 V to 5.25 V. The ADF4355 also contains hardware and software power-down modes.
Applications
- Wireless infrastructure (W-CDMA, TD-SCDMA, WiMAX, GSM, PCS, DCS, DECT)
- Point to point/point to multipoint microwave links
- Satellites/VSATs
- Test equipment/instrumentation
- Clock generation

Tools & Simulations
Design Tools
ADIsimPLL™
ADIsimPLL enables the rapid and reliable evaluation of new high performance PLL products from ADI. It is the most comprehensive PLL Synthesizer design and simulation tool available today. Simulations performed include all key non-linear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design- to-market.
ADIsimFrequency Planner Tool
For those developers dealing with integer boundary spurs from Analog’s PLL synthesizers, the best solution is ADIsimFrequencyPlanner. The frequency planner quickly analyzes the PFD frequency for a user’s output requirements and then optimizes the frequency of each output to identify the highest contributing integer boundary spur performance.
Design Resources
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.View our quality and reliability program and certifications for more information.
