Analog Ground
Analog Power-Supply Voltage. AVDD supply range is 3.0V to 3.6V. Bypass AVDD with a 0.1µF
capacitor to AGND.
AC Powerline Positive Input
AC Powerline Negative Input
External Capacitor Connection. Connect a 10nF capacitor from C
External Resistor Connection. Connect a 25kΩ resistor from R
AC Powerline Positive Output
AC Powerline Negative Output
Voltage Regulator Output. Connect REGOUT to DVDD for normal operation.
Digital 2.4V Voltage Input. Connect DVDD to REGOUT for normal operation.
Digital Ground
Serial Data Input/Output
Serial Clock Input
Receiver Shutdown Control. Drive SHRCV high to power down the receiver. Drive low for normal
operation.
Read-Mode Enable Control. Drive ENREAD high to place the DAD[9:0] bidirectional buffers in read
mode. Data is transferred from the digital PHY to the AFE DAC. ENREAD signal frames the
transmission.
Active-High Carrier-Select Input. Drive CS high to initiate the internal timer.
Digital Power-Supply Voltage. DVDD3 supply range is 3.0V to 3.6V. Bypass DVDD3 to DGND with a
0.1µF capacitor as close as possible to the pin.
50MHz System Clock Input
DAC/ADC Input/Output MSB Data Bit. Input/output of 10-bit, 50MHz bidirectional digital-to-analog
and analog-to-digital converter. Data is in binary format.
DAC/ADC Input/Output Data Bit 8. Input/output of 10-bit, 50MHz bidirectional digital-to-analog and
analog-to-digital converter. Data is in binary format.
