Ag1170
+5V / +3.3V LOW POWER RINGING SLIC
3.3 Network Balance Impedance.
The network balance impedance ZB of the Ag1170 is
set to 600R and it requires no external programming
resistors.
To programme the ZB for the Ag1170P components
are connected from the V
IN
pin to the ZB pin. For ZB =
ZT use a 100K resistor in series with a 47nF capacitor.
Further details on the programming of the Ag1170P are
contained within Applications Note: AN1170-1.
3.4 Tip & Ring Polarity Reversal.
The Ag1170 can reverse the battery voltage polarity at
Tip and Ring via the F/R pin.
If F/R is held at logic 1 (forward) the d.c. voltage at Tip
is positive with respect to Ring. If F/R is taken to logic
0 the voltage polarity is reversed.
3.5 On Hook Transmission.
The Ag1170 is capable of on-hook transmission. This
means analog signals can be transmitted from VIN
through Tip and Ring and onto the line even when no
loop current is flowing. This can be used when
sending Caller Line Identification (CLI) information or
for other “no ring” calls.
The Ag1170 will provide on hook transmission with a
high impedance on Tip/Ring or with AC loads down to
600R.
