ADF4355-2

Microwave Wideband Synthesizer with Integrated VCO

Manufactured by:

Product Details

The ADF4355-2 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 frequency. A series of frequency dividers permits operation from 54 MHz to 4400 MHz.

The ADF4355-2 has an integrated VCO with a fundamental output frequency ranging from 3400 MHz to 6800 MHz. In addition, the VCO frequency is connected to divide by 1, 2, 4, 8, 16, 32, or 64 circuits that allow the user to generate RF output frequencies as low as 54 MHz. For applications that require isolation, the RF output stage can be muted. The mute function is both pin and software controllable.

Control of all on-chip registers is through a simple 3-wire interface. The ADF4355-2 operates with analog and digital power supplies ranging from 3.15 V to 3.45 V, with charge pump and VCO supplies from 4.75 V to 5.25 V. The ADF4355-2 also contains hardware and software power-down modes.

Applications

  • Wireless infrastructure (W-CDMA, TD-SCDMA, WiMAX, GSM, PCS, DCS, DECT)
  • Point to point/point to multipoint microwave links
  • Satellites/VSATs
  • Test equipment/instrumentation
  • Clock generation

EVAL-ADF4355-2

EVAL-ADF4355-2 Circuit Diagram

Product Details

The EV-ADF4355-2SD1Z evaluates the performance of the ADF4355-2 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 ADF4355-2 frequency synthesizer with integrated VCO, a differential 122.88 MHz reference (TCXO), a loop filter, a US interface, power supply connectors, and subminiature Version A (SMA) connectors. A USB cable is included to connect the board to a PC USB port.

For easy programming of the synthesizer, download the Windows-based software from www.analog.com/ADF4355-2.

This board requires an SDP-S (as shown above, but not supplied with the kit). The SDP-S allows software programming of the EV-ADF4355-2SD1Z device.

Product Details

The AD-FMCADC7-EBZ is a single channel high speed data acquisition board featuring the AD9625 12bit, ADC sampling at 2500 MSPS and a ADL5567 low distortion, 4.8 GHz, differential amplifier driving the converter. The FMC form factor supports the JESD204B high speed serial interface. All clocking is supported using the on-board ADF4355-2 wideband PLL with VCO. This product is designed for sampling wide bandwidth analog signals from DC to 1.8GHz. The combination of wide input bandwidth, high sampling rate, and excellent linearity of the AD9625 is ideally suited for spectrum analyzers, data acquisition systems, and a wide assortment of military electronics applications.


The board meets most of the FMC specifications in terms of mechanical size, mounting hole locations, and more. Although this board does meet most of the FMC specifications, it’s not meant as a commercial off the shelf (COTS) board. If you want a commercial, ready to integrate product, please refer to one of the many FMC manufacturers and the FMC specification (ANSI/VITA 57.1).


This board is targeted to use the ADI reference designs that work with Xilinx development systems. ADI provides complete source (HDL and software) to re-create those projects (minus the IP provided by the FPGA vendors, which we use), but may not provide enough info to port this to your custom platform.


The design of the board is specifically tailored to allow for true DC coupling on the analog input of the amplifier throughout the signal chain to the converter. Yielding the widest spectrum possible for the AD-FMCADC7-EBZ.


The reference design includes the device data capture via the JESD204B serial interface and the SPI interface. The samples are written to the external DDR-DRAM. It allows programming the device and monitoring it’s internal registers via SPI.
