CLK-104a/b Boards Using Renesas RF-PLL and RF-Synthesizer Solutions Manual
2. Standalone Testing
If a Xilinx ZCU-1275 board is not available, the CLK-104 board can be tested standalone. Please complete the
following steps and information below to conduct a standalone test or evaluation.
2.1
Power Supply
The connector between the CLK-104 and ZCU-1275 contains +5V, +3.3V, and ground pins that provide power
supplies to the CLK-104 board when plugged in. Copper pads are available on the CLK-104 board to facilitate
the power supplies coming from a bench power supply. Solder a thick wire on these pads and connect +5V,
+3.3V, and GND to a bench power supply. For the locations of these copper pads, see the following figure.
Figure 3. +5V, +3.3V, and GND Copper Pads are Provided for Local Power Supplies
3. SPI Interface
A 5×2 header is installed to make connections between an external SPI master to the devices on the CLK-104
board. Use an FTDI dangle (C232HM) to connect the SCLK, SDI, SDO, and nCS signals as labelled in the
header below. Please note, jump J4, J5, or J6 one at a time to access one of three devices on the board.
