SMA Connector (J6)
The THDB-SUM board provides an SMA connector (J6) for external clock input.
Table 2–16 shows the pin assignments of the SMA connector.
Table 2–17 lists the SMA connector board reference and manufacturing information.
I 2 C Serial EEPROM (U10)
The THDB-SUM board provides an EEPROM (U10) which can be configured by the
I
2 C interface. The size of the EEPROM is 2 Kbits and it can store board information or
user’s data. Figure 2–15 shows the pin-outs of the EEPROM. Table 2–18 lists the
detailed pin mapping between the EEPROM and the HSMC connector.
