    RC38612 Evaluation Kit Manual Note: VDD_FOD voltage is selected by resistor R908 and R909. In order to prevent damage to the device, both R908 and R909 should not be stuffed, in which case VDD_FOD = 1.8V. GPIO Switches, LEDs, and Test Points An 8-bit, 3-position dip switch is used to set the logic levels for seven GPIOs (GPIO0-5, GPIO9).

    RC38612 Evaluation Kit Manual I2C between FTDI, ClockMatrix Device, and On-board EEPROM One of the major differences between the QFN-72 ClockMatrix device and its BGA-144 counterpart is that there is only one serial bus on the QFN-72 device. The I2C bus between the FTDI chip and ClockMatrix device is the same bus between the ClockMatrix device and the on-board EEPROM.
  • Page 7 RC38612 Evaluation Kit Manual Figure 5. Board Setting for Default Operation Note: In order to set GPIO9 to “High”, the switch for GPIO9 must be set either to the “+” (high) position or the center position. Before proceeding to communicate to the ClockMatrix device using the Timing Commander GUI, two I2C connection methods are introduced: 1.
