Description
Connects the CS pin of the ADE7953 to ADuM1401 Isolator U5. Use this configuration when communicating with
the ADE7953 via the interface board using SPI.
Disconnects the CS pin of the ADE7953 from ADuM1401 Isolator U5. Use this configuration when isolation and/or
SPI communication is not required with the ADE7953.
Connects the CS pin of the ADE7953 to the externally applied 3.3 V power. Use this configuration when using
either I²C or UART communication.
Disconnects the CS pin of the ADE7953 from the externally applied 3.3 V power. Use this configuration when the
ADE7953 is configured for SPI communication.
Connects the REVP pin of the ADE7953 to ADuM1401 Isolator U4. Use this configuration in normal operation when
software management of the REVP pin is done via the interface board and the ADE7953 evaluation software.
Disconnects the REVP pin of the ADE7953 from ADuM1401 Isolator U4. Use this configuration when software
management of the REVP pin is not desired.
Connects the CF1 pin of the ADE7953 to CF1_ISO BNC Connector J1 via ADuM1401 Isolator U4. Use this
configuration when the isolated interface to CF1 is required.
Disconnects the CF1 pin of the ADE7953 from CF1_ISO BNC Connector J1 via ADuM1401 Isolator U4. Use this
configuration when the isolated interface to CF1 is not required.
Connects the CF2 pin of the ADE7953 to CF2_ISO BNC Connector J2 via ADuM1401 Isolator U5. Use this
configuration when the isolated interface to CF2 is required.
Disconnects the CF2 pin of the ADE7953 from CF2_ISO BNC Connector J2 via ADuM1401 Isolator U5. Use this
configuration when the isolated interface to CF2 is not required.
