This section describes the Santa Cruz connector on the THDB-SUM board
The THDB-SUM board comes with Santa Cruz connectors (J3, J4 and J5) to connect to a daughter board with
Santa Cruz interface. On the THDB-SUM, the pin of SC connector not directly connects with HSMC connector.
Owing to the limitation of number of HSMC connector I/O pins, SC connector and USB transceiver share some
I/O pins together, Please refer to
HSMC connector. Therefore users can only choose one function between SC connector and USB transceiver.
Users can refer to
In addition, from the
chips convert the logic levels of the signals between the HSMC and Santa Cruz connectors according to the
configurations of the headers (JP3, JP4). With this feature, users can use different I/O standards between the
HSMC host board and SC interface daughter board.
