Name
Function
Low-voltage (CPE) side power supply
Transmit summing junction
Negative differential transmit signal to DAA
from low-voltage side
Positive differential transmit signal to DAA from
low-voltage side
Transmit differential amplifier output
When asserted low, changes gain of TX path
(-7 dB) and RX path (+7 dB) to accommodate
reactive termination networks
Low-voltage (CPE) side analog ground
Assert logic low for off-hook operation
Ringing Detect Output
Assert logic low while on hook to allow CID
information to be passed to the RX+ and RX-
output pins.
Negative differential analog signal received
from the telephone line. Must be AC coupled
with 0.1 μF.
Positive differential analog signal received from
the telephone line. Must be AC coupled with
0.1 μF.
Positive differential snoop input
Negative differential snoop input
Receive photodiode amplifier output
Receive photodiode summing junction
Power supply for line side, regulated from tip
and ring.
Receive isolation amp summing junction
Receive LED pre-bias current set
Bridge rectifier return
Electronic inductor DCR/current limit
DC feedback output
V to I slope control
Network amplifier feedback
External MOSFET gate control
