Model ADF4157 Fractional-N PLL synthesizer operates up to 6 GHz using power supply ranging from 2.7-3.3 V and can be powered down when not in use for current reduction from 23 mA to 0.01 mA. It consists of low-noise digital phase-frequency detector, precision high-voltage charge pump, programmable reference divider, programmable charge pump currents, and 25-bit fixed-modulus fractional divider. Three-wire interface controls all on-chip registers.
With the industry's finest resolution, ADI's ADF4157 Fractional-N PLL synthesizer improves performance while reducing design cost and complexity in wireless infrastructure, satellite and radio systems.
