Pad ring power pins (VDDO[3:0]).
These pins must be connected to a
common, well decoupled +5 VDC
supply together with the VDDI[1:0]
pins. Care must be taken to avoid
coupling noise induced on the VDDO
pins into the VDDI pins.

Notes on Pin Description:
1. VDDI and VSSI are the +5 V and ground connections, respectively, for the
core circuitry of the device. VDDO and VSSI are the +5 V and ground
connections, respectively, for the pad ring circuitry of the device. TAVD and
TAVS are the +5 V and ground connections, respectively, for the transmit
analog circuitry of the device. These power supply connections must all be
utilized and must all connect to a common +5 V or ground rail, as appropriate.
There is no low impedance connection within the PM6341 between the core,
pad ring, and transmit analog supply rails. Failure to properly make these
connections may result in improper operation or damage to the device. Care
must be taken to avoid coupling of noise into the transmit analog supply rails.
2. RAVD and RAVS are the +5 V and ground connections, respectively, for the
receive analog circuitry of the device. These power supply connections need
