Core Ground Pins (VSSI[15:1]). These pins must
be connected to a common ground together with
the VSSO[6:1], TAVS[4:1], and RAVS[4:1]pins.
Care must be taken to avoid coupling noise
between these pins. These pins also act as
thermal-dissipation grounds, and as such should
be thermally well-connected to a ground plane.

Transmit Analog Power Pins (TAVD[4:1]). These
pins provide the +5 V supply to the transmit
analog line interfaces. The transmit analog line
interface remains in a low power consumption
state after reset until enabled. TAVD[4:1] must be
connected to a common well decoupled +5 V DC
power supply together with the VDDO[6:1],
VDDI[3:1], and RAVD[4:1] pins. Care must be
taken to avoid coupling noise between these
pins.
