Wideband synthesizer with integrated VCO that operates from 53.125 MHz to 6.8 GHz. It offers low phase noise, low spurious levels, and high phase-comparison frequency. It supports fractional-N or integer-N PLL modes and has a 52-bit modulus for fine-frequency resolution. A wideband synthesizer with integrated VCO that operates from 53.125 MHz to 13.6 GHz. It has similar features and performance as the ADF4356 but with a higher frequency range. It is pin-compatible with the ADF4356.
Features
The main features of ADF43xx series RF synthesizers may be summarized as follows:
1. Integrated RMS jitter (1 kHz to 20 MHz): 97 fs for 6 GHz output
2. Fractional-N synthesizer and integer-N synthesizer
3. Pin compatible with the ADF4355
4. High resolution, 52-bit modulus
5. Phase frequency detector (PFD) operation to 125 MHz
6. Reference input frequency operation to 600 MHz
7. Maintains frequency lock over −40°C to +85°C
8. Low phase noise, voltage-controlled oscillator (VCO)
9. Programmable divide by 1, 2, 4, 8, 16, 32, or 64 output
10. Analog and digital power supplies: 3.3 V
Applications
Wireless infrastructure
Microwave point-to-point links
Electronic test and measurement
Satellite terminals
These applications require high-performance, wideband, and low-jitter frequency generation and synchronization.
