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 voltage controlled oscillator (VCO) design permits frequency operation from 7300 MHz to 14600 MHz at a single radio frequency (RF) output. A series of frequency dividers with a differential frequency output allows operation from 57 MHz to 14600 MHz. Analog and digital power supplies for the PLL circuitry range from 3.1 V to 3.5 V, and the VCO supplies are between 4.75 V and 5.25 V. The charge pump supply voltage can be extended up to 3.6 V for improved frequency band overlap and extended upper frequency range.

The ADF5610 has an integrated VCO with a fundamental frequency of 3650 MHz to 7300 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, or 128, allowing the user to generate RF output frequencies as low as 57 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 output and the differential output are programmable via the VCO register settings. The ADF5610 also contains various power-down modes for the VCO circuitry 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 a typical spurious level of −100 dBc.

With phase noise levels from −115 dBc/Hz at 7.3 GHz to −109 dBc/Hz at 14.6 GHz, the ADF5610 is equipped to minimize blocker effects, and to improve receiver sensitivity and transmitter spectral purity. The low phase noise floor eliminates any contribution to modulator and mixer noise floor in transmitter applications.

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

Additional features of the ADF5610 include approximately 3 dB of RFOUT gain control in 1.5 dB steps and 5 dB of control on the differential port in approximately 2.5 dB steps. Finally, the Δ-Σ modulator with exact frequency mode enables users to generate output frequencies with 0 Hz frequency error.

    Product Detail

    The EV-ADF5610SD1Z evaluates the performance of the ADF5610 frequency synthesizer with integrated VCO for phase-locked loops (PLLs). A photograph of the evaluation board is shown in Figure 1. The evaluation board contains the ADF5610 synthesizer with integrated voltage controlled oscillator (VCO), a low noise, single-ended, 50 MHz voltage controlled crystal oscillator (VCXO) reference, the HMC1031 Integer N PLL, a switch, a jumper, a loop filter, a USB interface, and subminiature Version A (SMA) connectors.

    For easy programming of the synthesizer, download the Windows®-based software from the ADF5610 page at ftp://ADF5610_ftp:ZagrJ6Fx@ftp.analog.com. The file transfer program (FTP) user name and password are printed on the label inside the lid of the evaluation board box. The user manual and evaluation printed circuit board (PCB) schematic can also be found on the FTP site.

    The EV-ADF5610SD1Z evaluation board requires a SDP-S controller board (see Figure 3), which is not included with the kit. The SDP-S allows software programming of the ADF5610 device through a USB interface.

    Full specifications for the ADF5610 wideband microwave synthesizer are available in the ADF5610 data sheet, which must be consulted in conjunction with this user guide when working with the evaluation board.
