Analog Devices ADF4157 6 GHz Fractional-N Frequency Synthesizer Datasheet
The ADF4157 is a 6 GHz fractional-N frequency synthesizer designed for applications such as satellite communications terminals, radar equipment, and wireless handsets. It features a low noise digital phase frequency detector (PFD), a precision charge pump, and a programmable reference divider to allow subhertz frequency resolution at 6 GHz.
The device operates with a power supply ranging from 2.7 V to 3.3 V and includes cycle slip reduction circuitry for faster lock times without requiring modifications to the loop filter. Control of all on-chip registers is achieved via a simple 3-wire serial interface.
