            ADF4169 Fractional-N Frequency Synthesizer
                    Analog Devices’ synthesizer for communication systems and test equipment
    

Image of ADI's ADF4169 Fractional-N Frequency Synthesizer ADI’s ADF4169 is a 13.5 GHz, fractional-N frequency synthesizer that is complete with modulation and both fast and slow waveform generation capability. The part uses a 25-bit fixed modulus, allowing sub-hertz frequency resolution. This synthesizer can be used to implement frequency shift keying (FSK) and phase shift keying (PSK) modulation. Frequency sweep modes are also available to generate various waveforms in the frequency domain, for example, sawtooth, and triangular waveforms. The device comes in a 24-pin LFCSP package and has a temperature range of -40°C to +125°C. The ADF4169 is ideal for communication systems, test equipment, and FMCW radar.

Features
Analog voltage supply: 2.7 V to 3.45 V Digital voltage supply: 1.8 V to 2.0 V Frequency: 13.5 GHz 25-bit fixed modulus allows sub-hertz frequency resolution PFD frequencies up to 130 MHz		Normalized phase noise floor of -224 dBc/Hz FSK and PSK functions Temperature operating range: -40°C to +125°C Sawtooth, triangular, and parabolic waveform generation Package/case: 24-LFCSP (4 x 4)
Applications
Communication systems Test equipment		Frequency-modulated continuous wave (FMCW) radar
