ADF4371

Data Sheet Microwave Wideband Synthesizer with Integrated VCO ADF4371 FEATURES GENERAL DESCRIPTION RF output frequency range: 62.5 MHz to 32,000 MHz The ADF4371 allows implementation of fractional-N or Integer N Fractional-N synthesizer and Integer N synthesizer phase-locked loop (PLL) frequency synthesizers when used with High resolution 39-bit fractional modulus an external loop filter and an external reference frequency. The Typical spurious PFD: −90 dBc wideband microwave voltage controlled oscillator (VCO) design Integrated rms jitter: 38 fs (1 kHz to 100 MHz) allows frequencies from 62.5 MHz to 32 GHz to be generated. Normalized phase noise floor: −234 dBc/Hz PFD operation to 250 MHz Reference frequency operation to 600 MHz Programmable divide by 1, 2, 4, 8, 16, 32, or 64 output 62.5 MHz to 8,000 MHz output at RF8x and RFAUX8x 8,000 MHz to 16,000 MHz output at RF16x 16,000 MHz to 32,000 MHz output at RF32x Lock time approximately 3 ms with automatic calibration Lock time <30 μs with autocalibration bypassed Analog and digital power supplies: 3.3 V VCO power supply: 3.3 V and 5 V RF output mute function 7mm × 7mm, 48-terminal LGA package The ADF4371 has an integrated VCO with a fundamental output frequency ranging from 4000 MHz to 8000 MHz. In addition, the VCO frequency is connected to divide by 1, 2, 4, 8, 16, 32, or 64 circuits that allows the user to generate radio frequency (RF) output frequencies as low as 62.5 MHz at RF8x.
