DET
O
Detector output. Active low when indicating
loop or ring-trip detection, active high when
indicating ground key detection.

VR
I
Low voltage ring signal input.

AGND
I
Analog Ground, shall be tied to BGND.

RSN
I
Receive Summing Node. 400 times the
current flowing out of this pin equals the
metallic (transversal) current flowing from
RINGX to TIPX. Programming networks for
two-wire impedance and receive gain
connect to the receive summing node.
28
23
VTX
O
Transmit vf output. The AC voltage difference
between TIPX and RINGX, the AC metallic
voltage, is reproduced at VTX with a gain of
0.5. The two-wire impedance programming
network connects between VTX and RSN.

Not Connected, must be left open.
1) A batwing is a package pin, which provides a low thermal resistance path to the silicon chip via the lead frame.
By soldering the batwing pins to PCB copper foil the device can be efficiently cooled. Note that batwing pins
are at the same voltage as the VBAT pin (substrate voltage).
2) Exposed pad should be connected to V
BAT, note that this is used for cooling the chip.
