 | Kit Overview
The EVAL-ADF4350EB2ZEVAL-ADF4350EB2Z is designed to evaluate the performance of the ADF4350ADF4350 frequency synthesizer. It contains the ADF4350BCPZADF4350BCPZ synthesizer, a USB connector and related inter-face, a 10 MHz TCXO reference source, SMA connectors for the RF outputs, and reference signal plus headers for various signals and voltages. There is also a loop filter (20 kHz) on board. A USB cable is included with the board to connect to a PC USB port. The package also contains Windows
The EVAL-ADF4350EB2ZEVAL-ADF4350EB2Z can be powered either from the USB port or via dc power connectors (4 mm banana connec-tors). When feeding via banana connectors, 3.75 V to 11 V is a suitable feeding voltage. The power supply circuitry allows the user to use one, two, or three separate LDOs to feed the ADF4350 (using fewer LDOs increases the risk of spur contaminated dc feeds).
The EVAL-ADF4350EB2ZEVAL-ADF4350EB2Z has four SMA output connectors (dual differential output). The device is quite sensitive to impedance unbalance. If only one port of a differential pair is used, terminate the other with a 50 Ω load.
The ADF4350ADF4350 allows implementation of fractional-N or integer-N phase-locked loop (PLL) frequency synthesizers if used with an external loop filter and external reference frequency.
Key Applications: Wireless infrastructure (W-CDMA, TD-SCDMA, WiMAX, GSM, PCS, DCS, DECT), Test equipment, Wireless LANs, CATV equipment, Clock generation | |||||||||||

Software Tools
The control software for the EVAL-ADF4350 accompanies the EVAL-ADF4350EB1Z on a CD. The software allows you to control of synthesizer functions from a PC, including
- set correct reference frequency and reference frequency divider
- controls the charge pump current setting, the output power setting, and the multiplexer output setting
- control the output frequency
- select Low Spur Mode or Low Noise Mode for the frac-N mode
- displays selected settings & every bit of the register settings
