TAVD
Power
Transmit Analog Power (TAVD). This
pin provides the +5 V supply to the
transmit analog line interface. Even if
the transmit analog line interface is
not used, a +5 V supply must be
provided. The transmit analog line
interface remains in a low power
consumption state after reset until
enabled. TAVD must be connected to
a common, well decoupled +5 VDC
supply together with the VDDO[3:0]
and VDDI[1:0] pins. Care must be
taken to avoid coupling noise induced
on the VDDO and VDDI pins into the
TAVD pin.
TAVS
Ground 65

Transmit Analog Ground (TAVS). This
pin provides the ground supply to the
transmit analog line interface. TAVS
must be connected to a common
ground together with the VSSO[3:0]
and VSSI[1:0] pins. Care must be
taken to avoid coupling noise induced
on the VSSO and VSSI pins into the
TAVS pin.
