Product Details

The ADF5610 allows implementation of fractional-N or integer- N phase-locked loop (PLL) frequency synthesizers when used with an external loop filter and an external reference source. The wideband microwave VCO design permits frequency operation from 7000 MHz to 15000 MHz at a single radio frequency (RF) output. A series of frequency dividers with a differential frequency output allows operation from 55 MHz to 15000 MHz. Analog and digital power supplies for the phase locked loop (PLL) circuitry range from 3.0 V to 3.6 V, and the voltage controlled oscillator (VCO) supplies are between 4.75 V to 5.25 V. The charge pump can be operated up to 3.6V for improved frequency band overlap and extended upper frequency range.

The ADF5610 has an integrated VCO with a fundamental frequency of 3500 MHz to 7000 MHz. These frequencies are internally doubled and routed to the RFOUT pin. An additional differential output allows the doubled VCO frequency to be divided by 1, 2, 4, 8, 16, 32, 64 and 128 allowing the user to generate RF output frequencies as low as 55 MHz. A simple 3-wire serial port interface (SPI) provides control of all on-chip registers. To conserve power, this divider block can be disabled when not needed through the SPI interface. Likewise, the output power for both the single ended and differential outputs are programmable via VCO registers settings. The ADF5610 also contains power-down modes for the VCO and PLL circuitry.

The integrated phase detector (PD) and delta-sigma (Δ-Σ) modulator, capable of operating at up to 100 MHz, permit wide loop bandwidths and fast frequency tuning with excellent spectral performance.

Industry leading phase noise and good spurious performance, across all frequencies, enable the ADF5610 to minimize blocker effects, and to improve receiver sensitivity and transmitter spectral purity. The low phase noise floor eliminates any contribution to modulator/mixer noise floor in transmitter applications.

The ADF5610 is a market leading PLL with integrated VCO. It features an innovative programmable performance technology that enables the ADF5610 to tailor current consumption and corresponding noise floor performance to individual applications by selecting either a low current consumption modes or a high performance mode for improved noise floor performance.

Additional features of the ADF5610 include 4dB of RFOUT gain control in 1 dB steps and approximately 6dB of control on the differential port in approximately 3dB steps. Finally the Δ-Σ modulator with exact frequency mode enables users to generate output frequencies with 0 Hz frequency error.
