DESCRIPTION The Silver Telecom Ag1170 is a single Subscriber Line Interface Circuit (SLIC) in a 14 pin single in line (SIL) or 21 pin dual in line (DIL) format. The combination of features and packaging offers extremely efficient use of board area, saving significant system size and cost, minimising time to market for Telephony Systems developers. The Ag1170 has been designed to work with loop lengths of up to 3.0km (800Ω including telephone). Its performance to regulatory standards (G713) allows use in public and private network applications. The Ag1170 has integral dc/dc converter and ringing generation thus providing all the line powering requirements from a single supply. The SLIC requires a minimum of external components. The system interface has been designed for connection to all popular codecs of both the audio and signalling connections. The Ag1170 is ideal for low line count and high line count, short loop length applications, such as ISDN Terminal Adaptors, Internet Telephony (VoIP), Computer Telephony Integration (CTI), Wireless Local Loops (WLL) and Small Office Home Office (SOHO). © Silver Telecom 2003 旭捷電子有限公司 Tel :02-29955600 Ag1170 V1.0 June 2003 Data Sheet +5V / +3.3V LOW POWER RINGING SLIC Ordering Information Ag1170-D5 Ag1170-D3 +5V Ringing SLIC, DIL package +3.3V Ringing SLIC, DIL package Ag1170-S5 Ag1170-S3 +5V Ringing SLIC, SIL package +3.3V Ringing SLIC, SIL package Above Options also available in the Ag1170P, Programmable Impedance Version Ag1170-D 5/3.3 Low Power Ringing SLIC Silver TELECOM Figure 1: DIL Variant Packaging Format Silver Ag1170S TELECOM Figure 2: SIL Variant Packaging Format Line Reversal and Ringing Control Tip RM F/R Supervision 2-4 Wire Converter and Line Interface Ring SHK VOUT VIN Power Management and DC-DC converter GND A VA *ZB *Only used for the Ag1170P device. *ZT1 *ZT2 VPWR GND PWR SYNC No Connect for the Ag1170 as the impedances are programmed to 600R internally.

The Ag1170 SLIC provides a complete and flexible interface to the telephone line. 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 and GND is needed, unlike conventional SLICs which will 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 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. Because the line is supplied with only as much power as needed, efficiency is good. Little excess heat is generated, even on short lines. The loop current is pre-set to a constant 24mA. If the loop length is such that the constant current feed cannot be maintained (i.e. >3km), then the Ag1170 will revert to a constant voltage source, allowing the loop to be serviced at a reduced loop current. 2.2 Ringing 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 balanced signal at Tip and Ring. These signal waveforms are shown in Figure 5. 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. 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) 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 correctly up to a maximum loop resistance of around 800R (including telephone), which corresponds to around 3km loop length. 2.3 Synchronisation and Power Down The DC/DC has in internal oscillator. If it is desired to synchronize the frequency with an external clock for EMI reasons, a 128kHz (+5V) or 64kHz (+3.3V) square wave (50:50 mark space) should be input to the SYNC pin. The DC/DC converter can be switched off by applying a logic 0 to the SYNC input. The SLIC takes 50ms to power up from this powered down state. When using the power down state it is recommended that the SLIC is polled (powered up periodically) to check for SHK (the subscriber has gone off hook). If not in SYNC mode or PD the SYNC pin should be left open circuit. An open collector gate should be used for applying the PD signal. Never connect a logic high to this pin. See Figure 4 for details. 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 For internal oscillator “free run” with no SYNC or PD – leave SYNC pin open circuit For SYNC or PD use an AND gate For PD only use a transistor To SYNC pin SYNC 0V to +3/+5V Square Wave & H = SYNC L = PD To SYNC pin 10K BC846 or equivalent H = PD L = Free Run GND SYNC/PD input must be: 1)Square wave, or 2)Logic low, or 3)Open circuit. It must NEVER be logic high – this will damage the DC-DC Converter Figure 4: Sync/PD Control © Silver Telecom 2003 Page 5 Ag1170 V1.0 June 2003 Data Sheet +5V / +3.3V LOW POWER RINGING SLIC Condition 1 - DC ope ration Signal INPUT RM Notes 1 No ringing 0 OUTPUT SHK 1 Off hook detected 0 NO TE: SHK SHOULD BE DE-BOUNC ED Off Hook Condition 2 - Ringing On-hook 1 RM 1 sec 3 sec Condition 3 - Ringing/Off-hook 1 sec 3 sec 0 1 F/R (input) 0 SHK 1 0 The phone goes off hook, and SHK is detected at point A (leading edge).

Figure 5: Ringing Signal Waveforms VOUT and from a ground referenced input at VIN. VOUT and VIN are normally connected to a Codec for conversion to and from a digital Pulse Code Modulated (PCM) stream. The impedance ratio for ZT is 100. Resistors should be multiplied by this ratio and capacitor values divided to obtain the required programming values e.g. for 600R impedance fit 6K resistor (nearest value = 6.2K). 3.3 Network Balance Impedance. 3.1 Transmit and Receive Gain. The gain in both the transmit direction (Tip/Ring to 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. The network balance impedance ZB of the Ag1170 is set to 600R. ZB of the Ag1170P is programmed by connecting external components between pins VIN and ZB. For ZB = ZT use a 100K resistor 3.4 Tip & Ring Polarity Reversal. 3.2 The 2 Wire Impedance. The Ag1170 can reverse the battery voltage polarity at Tip and Ring via the F/R pin. The impedance at Tip/Ring of the Ag1170 is set to 600R. The impedance of the Ag1170-P can be programmed to the required value by connecting components across pins ZT1-ZT2. 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. © Silver Telecom 2003 Page 6 Ag1170 V1.0 June 2003 Data Sheet +5V / +3.3V LOW POWER RINGING SLIC R2 +5V/+3.3V Components C1, C3, C5, C6 = 100nF C2 = 220uF, 10V, Rubycon ZL (or equivalent low ESR) C4 = 100uF, 16V R2 = 10R D1 = BZT03C75 or P6KE75 (only one needed per line card) D2 – 5 = 1N4004 or MB4S bridge C2 + C4 + C3 C1 +V PWR +V A GNDPWR GNDPWR/ GNDA Ag1170 To Micro Controller D2 TIP SHK RM TIP D3 Silver D4 RING T EL EC O M RING V OUT D5 SYNC D1 F/R V IN C5 To Codec C6 To other circuits Figure 6: Typical Connection Diagram 3.5 On Hook Transmission. by the DC/DC converter 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. This feature means that the SLIC will always operated 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. The Ag1170 will provide on hook transmission with a high impedance on Tip/Ring or with AC loads down to 600R. 5.2 Lightning and Power Cross Protection. 4.0 Switch Hook Detect Level 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. 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 debouncing is used to avoid false detection of digits. 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 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 6. This circuit is suitable for most “onpremise” applications. 5.1 Thermal Protection 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. 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 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 5.0 Protection of the Ag1170 SLIC © Silver Telecom 2003 Page 7 Ag1170 V1.0 June 2003 Data Sheet +5V / +3.3V LOW POWER RINGING SLIC impedances the Ag1170-P can be used. This can be programmed using external components (Section 3.2 and 3.3). 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. 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 7 for details. 6.0 Approvals. It can be seen from the Electrical Characteristics given on subsequent pages that the SLIC has been designed to meet the equipment standards of as many major public telephone authorities as possible.

Every effort is made to ensure that Silver Telecom products are compliant with the latest standards. ZB Ring 1nF 1nF VOUT 100pF 7.0 A Typical Application. Figure 7: Optional EMI Suppression The Ag1170 has been designed to interface to any Codec. Applications drawings for many codecs and DSP chips are available. Please contact Silver Telecom or visit www.silvertel.com. An example is shown in figure 6. The status outputs from the SLIC are passed to the micro-controller. These signals can then be processed as necessary by the system software. 7.1 Layout Considerations. Figure 7 gives an example of the tracking needed for the Ag1170. Tracks to the +VPWR and GNDPWR should be made as thick as possible. To maximise the performance of the device signal tracks should be kept as short as possible. A low impedance (ESR) capacitor must be used for C2. To reduce DC/DC noise capacitors up to 10nFmay be connected to ground at Tip and Ring. The audio signals which are on the 4 wire side of the connection are coupled by 100nF capacitors to avoid d.c. level problems between the two devices. The Ag1170 provides for a 2 wire impedance and a network balance impedance of 600Ω.
