PQFP PLCC
Function
RRC
I/O
52
54
Receive Peak Hold R-C Network
(RRC). This analog bidirectional pin is
connected to an external parallel
resistor/capacitor network to RAVS.
This network is necessary to the
operation of the internal peak detector
that tracks the incoming signal level.
RAVD
Power
55
57
Receive Analog Power (RAVD). This
pin provides the +5V supply to the
receive analog line interface. If the
receive analog line interface is not
used, the power consumption of the
E1XC can be reduced by connecting
the RAVD pin to the analog ground
pin, RAVS. RAVD 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
RAVD pin.
RAVS
Ground 54
56
Receive Analog Ground (RAVS). This
pin provides the ground supply to the
receive analog line interface. RAVS
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
RAVS pin.
