also guaranteed not give a false ring trip with a load of
3 REN.
2.0 Line Interfacing
As well as being used in an electrically demanding
environment, the needs of different applications and
regulatory standards means that the SLIC must be
flexible, and have facilities to ensure robust
performance. The Ag1170 SLIC provides a complete
and flexible interface to the telephone line.
2.3 Power Down and Synchronisation
The DC/DC converter can be switched off by applying
a logic 0 to the PD input. The SLIC takes 50ms to
power up from this powered down state. Logic outputs
are not valid during this time. When using the power
down function, it is recommended that the SLIC is
polled (powered up periodically) to check for SHK (the
subscriber has gone off-hook). If not in Power Down
mode, the PD pin should be left open circuit. An open-
collector gate should be used for applying the PD
signal. Never connect a logic high to the PD pin.
NOTE: This is a sensitive node; keep connections very
short.
2.1 Battery Feed
The Ag1170 has an integral DC/DC converter, which
generates the battery voltage in the device. This
means that only a supply of +5V or 3.3V is needed,
unlike conventional SLICs which will also need a
battery voltage of anything between -20V and -60V
(-75V for ringing). This confers a significant cost, space
and time to market benefit on the equipment designer.
The DC/DC has an internal oscillator. If desired, the
oscillator frequency may be synchronised with an
external clock for EMI reasons. To do this, a 128kHz
(+5V) or 64kHz (+3.3V) square wave (with 50:50 mark
space) should be inputted to the PD pin. See
Applications Note: AN1170-12, for further details.
The battery feed to the telephone line is generated
from the positive supply rail. This provides a -48V
battery feed to the line driver, which is adjusted
automatically to match line conditions.
Power efficiency is good, because the line is supplied
with only as much power as is needed. Little excess
heat is generated, even on short lines. The loop current
is pre-set to a constant 24mA, under the conditions
shown in Section 9.3 of this datasheet, which specifies
the ‘DC Electrical Characteristics’ for the Ag1170.
3.0 The 2-4 Wire (hybrid) Conversion.
The Ag1170 SLIC transmits and receives balanced
2-wire analog signals at the Tip and Ring connections.
These are converted to a ground referenced output at
VOUT and from a ground referenced input at VIN.
2.2 Ringing
The VOUT and VIN pins are normally connected to a
Codec for conversion of audio to and from a digital
Pulse Code Modulated (PCM) stream.
The ringing signal is generated by switching the SLIC
into ringing mode, by setting the RM pin high, and then
toggling the F/R pin at the required frequency and
cadence. The toggling of the F/R pin produces a
3.1 Transmit and Receive Gain.
balanced signal at Tip and Ring.
These signal
The gain in both the transmit direction (Tip/Ring to
waveforms are shown in Figure 4. Ringing voltage of
approximately 65Vrms is applied to a single handset. It
is important that the RM pin is only set high during
ringing and that this pin is set low at all other times.
Applications Note AN1170-14 provides advice on how
to implement this requirement.
VOUT) and the receive direction (VIN to Tip/Ring) is set to
0dB. Normally any gain adjustments required by the
user can be made by programming the Codec.
3.2 The 2 Wire Impedance.
During ringing the integral DC/DC converter
automatically switches to produce a battery voltage of
-72V. This will produce greater than 40Vrms into a
REN of 3. The slope of the edges on the ringing
waveform is set internally to give the correct waveform
with 20Hz to 25Hz ringing frequency.
The 2 Wire impedance at Tip/Ring of the Ag1170 is set
to 600R. It requires no external programming resistors.
The 2 Wire impedance of the Ag1170-P can be
programmed to the required value by connecting
components across pins ZT1-ZT2.
When an “off-hook” condition occurs during ringing, the
ring-trip circuit on the Ag1170 senses the loop current
flowing and signals the off-hook condition on the SHK
output. The SHK signal must be “de-bounced” (by the
controlling processor) for 10ms to remove any spurious
pulses. The DC/DC controller limits the power. The
Ag1170 will operate continuously with a ring-trip load.
The ring-trip function will operate up to a loop
resistance of typically 800R (including telephone). It is
The impedance ratio for ZT is 100. Resistors should be
multiplied by the ratio and capacitor values divided by
the ratio to obtain the required programming values.
E.g. for 600R impedance, fit 60K resistor (nearest
value = 62K).
Further details on the programming of the Ag1170P are
contained within Applications Note: AN1170-1.

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.
3.3 Network Balance Impedance.
The network balance impedance ZB of the Ag1170 is
set to 600R and it requires no external programming
resistors.
3.5 On Hook Transmission.
To programme the ZB for the Ag1170P components
are connected from the VIN pin to the ZB pin. For ZB =
ZT use a 100K resistor in series with a 47nF capacitor.
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.
Further details on the programming of the Ag1170P are
contained within Applications Note: AN1170-1.
The Ag1170 will provide on hook transmission with a
high impedance on Tip/Ring or with AC loads down to
600R.
3.4 Tip & Ring Polarity Reversal.
The Ag1170 can reverse the battery voltage polarity at
Tip and Ring via the F/R pin.

4.0 Switch Hook Detect Level
5.0 Protection of the Ag1170 SLIC
5.1 Thermal Protection
When the subscriber goes “off-hook” loop current will
begin to flow. If this current is above the detection
threshold (10mA) the switch hook output, SHK, will
switch to a logic 1. It is recommended that software or
hardware de-bouncing of the switch hook signal is
used. This is to avoid short pulses which can cause a
false switch hook output, triggering the incorrect
system response.
Should the SLIC be operated incorrectly, for example
by accidentally shorting Tip and Ring to each other or
to ground, the power dissipation is automatically limited
by the DC/DC converter
This feature means that the SLIC will always operate
within its power limits, without overheating. When
operating on very short lines the battery voltage is
regulated to a low value. This limits the power
dissipation and ensures the Ag1170 operates with a
minimum temperature rise.
During loop disconnect dialling, SHK will pulse
between logic 1 and logic 0 to indicate the digits being
dialled. Again it is recommended that software de-
bouncing is used to avoid false detection of digits.

network balance impedance of 600Ω.
For other
impedances the Ag1170-P can be used. This can be
programmed using external components (Section 3.2
and 3.3).
It is usual for the Ag1170 to be used in “on-premise”
applications, such as SOHO, CTI and VoIP. In this
case power cross and lightning protection is not
required. In most ‘off-premise’ applications,
a
subscriber circuit will be required to withstand over
voltage conditions which could be caused by lightning
or overhead power cables striking the telephone
7.1 DC Supply Voltage
During operation the DC Supply Voltage MUST be
regulated within the limits shown in the Electrical
Characteristics – Section 9.0 of this datasheet. Use of
a “clean” power supply is extremely important. Should
the VCC supply rail go above the Absolute Maximum
Rating of 5.5V, for even a short time, then permanent
damage to the Ag1170 is likely to result.
cables.
It is therefore normal in “off-premise”
applications to provide primary and secondary
protection circuits to prevent damage to the SLIC.
The Ag1170 has been designed to be able to use low
cost protection components, a typical circuit is shown
in Figure 5. This circuit is suitable for most “on-
premise” applications.
We also advise that the designer performs a full
system evaluation, under all possible performance
conditions, to ensure that the VCC Maximum rating is
not exceeded.
With some additional components, the Ag1170 will
meet UL60950 requirements: a series element should
be added - a combination of a fuse (e.g. 350mA,
Bussman C515 or Littlefuse 220003) and a surge
resistor (25R typically). Alternatively a Teccor F1250T
or F0500T fuse may be used without a surge resistor.
In some applications, additional EMI suppression may
be needed. In this instance 3 capacitors can be added
to filter out the higher frequencies of the DC-DC
converter. See figure 6 for details.
For ITU-T K20 power cross protection, a PTC
thermistor (eg. type JH330L) of 30R is suitable. The
lightning protection is provided by steering diodes
connected to 0V and upgrading D1 to a Tranzorb
device (Motorola or STM 1.5KE82A). For lightning and
UL60950 power cross protection, D1 should be
upgraded further (General Semiconductor or Semitron
5KP75). Just one Tranzorb is needed per linecard.
