ADF4382A
Overview
The ADF4382A is a high performance, ultra-low jitter, fractional-N phased-locked loop (PLL) with an integrated voltage controlled oscillator (VCO) ideally suited for local oscillator (LO) generation for 5G applications or data converter clock applications. The high performance PLL has a.
- Fundamental output frequency range: 11.5 GHz to 21 GHz
- Divide by 2 output frequency range: 5.75 GHz to 10.5 GHz
- Divide by 4 output frequency range: 2.875 GHz to 5.25 GHz
- Integrated RMS jitter at 20 GHz = 20 fs (integration bandwidth: 100 Hz to 100 MHz)
- Integrated RMS jitter at 20 GHz = 31 fs (ADC SNR method)
- VCO fast calibration time < 1 μs
- VCO autocalibration time < 100 μs
- Phase noise floor: -156 dBc/Hz at 20 GHz
- PLL specifications
- -239 dBc/Hz: normalized in-band phase noise floor
