The EVAL-ADF4158EB1Z is an evaluation board used to evaluate the performance of the ADF4158 direct modulation/waveform generating, 6.1GHz fractional N frequency synthesiser. It contains the ADF4158 synthesiser, a PC connector, SMA connectors for the power supplies, and an RF output. There is also a low pass loop filter (20KHz) and a VCO (Z Communications, Inc., VCO940ME03 5.8GHz) on-board. The evaluation board is set up for a 10MHz PFD comparison frequency. An on-board TCXO provides the 10MHz reference frequency. A USB cable is included with the board to connect to a PC USB port. It consists of a low noise digital phase frequency detector (PFD), a precision charge pump, and a programmable reference divider. There is a sigma delta (Σ-Δ) based fractional interpolator to allow programmable fractional N division. The ADF4158 can be used to implement frequency shift keying (FSK) and phase shift keying (PSK) modulation.
