Description
Reverse Power Output Indicator. See the Reverse Power section. This pin can be configured to output a
range of alternative power quality signals (see the Alternative Output Functions section).
Current Channel Zero-Crossing Output Pin. See the Current Channel Zero Crossing section. This pin can be
configured to output a range of alternative power quality signals (see the Alternative Output Functions
section).
Interrupt Output. See the ADE7953 Interrupts section.
Calibration Frequency Output 1.
Calibration Frequency Output 2.
Serial Clock Input for the Serial Peripheral Interface. All serial communications are synchronized to the
clock (see the SPI Interface section). If using the I 2 C interface, this pin must be pulled high. If using the
UART interface, this pin must be pulled to ground.
Data Output for SPI Interface/Bidirectional Data Line for I 2 C Interface/Transmit Line for UART Interface.
Data Input for SPI Interface/Serial Clock Input for I 2 C Interface/Receive Line for UART Interface.
Chip Select for SPI Interface. This pin must be pulled high if using the I 2 C or UART interface.
Exposed Pad. Create a similar pad on the PCB under the exposed pad. Solder the exposed pad to the pad
on the PCB to confer mechanical strength to the package. Connect the pad to AGND and DGND.
