GENERAL DESCRIPTION

The

frequency synthesizer, and programmable attenuator. The

device covers an operating frequency range from 100 MHz

to 2400 MHz for use in satellite, cellular, and broadband

communications.

The

frequency synthesizer with integrated VCO, providing less than

1 Hz frequency resolution, and a 47 dB digitally controlled

output attenuator with 1 dB steps.

Control of all the on-chip registers is through a user-selected

SPI interface or I

power supply ranging from 4.75 V to 5.25 V.
