GENERAL DESCRIPTION

The ADRF6755 is a highly integrated quadrature modulator,

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 ADRF6755 modulator includes a high modulus, fractional-N

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 I²C interface. The device operates from a single power

supply ranging from 4.75 V to 5.25 V.
