15.1.3. Frequency and Voltage Adjustment
15.1.3.1. Settings and Connecting
Please connect a Frequency counter to "RFCLK" point on the Digital Board located near the RF unit.
Please connect a Digital multimeter to "+1.8V" point on the Digital Board located near the BBIC.
See the Adjustment Standard (Base Unit) (P.273).
15.1.3.2. Frequency Adjustment
Adjustment value of frequency is the command "SFR".
(default value: 75)
After inputting "EPD_F", please check the RF clock and
input "SFR".
If Frequency displayed on the frequency counter is lower
than 10.368000MHz, please decrease the value. In order to
do it, please write a value with "SFR **" command.
If you decrease 1, input "SFR 74".
If frequency is higher, please write increased value to.
15.1.3.3. Voltage Adjustment
Adjustment value of voltage is the command "VDD".
(default value: 08)
If 1.8V_voltage displayed on the Digital multimeter is higher
than 1.85V, please decrease the value.
Please write a value with "VDD **" command.
If you decrease 1, input "VDD 07".
If voltage is lower, please write increased value to.
Note:
When you write new value to the EEPROM, it is necessary to turn the power off and then power on again.
