This document presents the steps to setup an environment for using the EVAL-ADF4001SD1Z evaluation board together with the Xilinx KC705 FPGA board and the Xilinx Embedded Development Kit (EDK). Below is presented a picture of the EVAL-ADF4001SD1Z Evaluation Board with the Xilinx KC705 board.

For component evaluation and performance purposes, as opposed to quick prototyping, the user is directed to Analog Devices System Demonstration Platform (SDP). The SDP consists of a:

• a controller board, like the EVAL-SDP-CS1Z (SDP-S)
• a compatible Analog Devices SDP product evaluation board
• corresponding PC software

The EVAL-SDP-CS1Z controller board is Serial Interfaces Only, low cost, reduced functionality controller board. It has a USB to Serial Engine at its core. It connects to the PC through a USB 2.0 high speed port. The SDP-S has a single 120 pin connector and exposes SPI, I2C and GPIO interfaces to connected SDP daughter boards.

The EVAL-ADF4001SD1Z is designed to allow the user to evaluate the perfor-mance of the ADF4001 frequency synthesizer for phase-locked loops (PLLs). Figure 1 shows the board, which contains the ADF4001 synthesizer, an SMA connector for the reference input, power supplies, and an RF output. There is also a footprint for a loop filter and a VCO on board.

The ADF4001 frequency synthesizer can be used to implement clock sources for PLLs that require very low noise, stable reference signals. It consists of a low-noise digital PFD (Phase Frequency Detector), a precision charge pump, a programmable reference divider, and a programmable 13-bit N counter. In addition, the 14-bit reference counter (R Counter), allows selectable REFIN frequencies at the PFD input. A complete PLL (Phase-Locked Loop) can be implemented if the synthesizer is used with an external loop filter and VCO (Voltage Controlled Oscillator) or VCXO (Voltage Controlled Crystal Oscillator). The N min value of 1 allows flexibility in clock generation.

The first objective is to ensure that you have all of the items needed and to install the software tools so that you are ready to create and run the evaluation project.

• Xilinx KC705 FPGA board
• FMC-SDP adapter board
• EVAL-ADF4001SD1Z evaluation board

• Xilinx ISE 14.6.
• UART Terminal (Termite/Tera Term/Hyperterminal), baud rate 115200.

• Use the FMC-SDP interposer to connect the ADI evaluation board to the Xilinx KC705 board on the FMC LPC connector.
• Connect the JTAG and UART cables to the KC705 and power up the FPGA board.

The following commands were implemented in this version of EVAL-ADF4001SD1Z reference project for Xilinx KC705 FPGA board.

Commands can be executed using a serial terminal connected to the UART peripheral of Xilinx KC705 FPGA.

The following image shows a generic list of commands in a serial terminal connected to Xilinx KC705 FPGA's UART peripheral.
