Function
Subscriber loop connection RING
Subscriber loop connection TIP
Battery ground: reference for TIP, RING, VBATH, VBATL and VHR
(5 V
(–20 V
Analog ground: reference for VDD and all signal and control pins
except TIP and RING
Common mode line potential with high output resistance (160 k ); an
external capacitance allows supply voltage filtering
ACP - ACN: differential two-wire AC input voltage; at TIP/RING
amplified by -6
DCP - DCN: differential DC or ring input voltage; at TIP/RING
amplified by -30 (ACTL, ACTH) and -60 (ACTR mode), respectively
Ternary logic input, controlling the operation mode
Ternary logic input, controlling the operation mode
in case of thermal overload (chip temperature exceeding 165 °C) this
pin sinks a current of typically 150 A.
Current output: longitudinal line current scaled down by a factor of 100
Current output: transversal line current scaled down by a factor of 50
