The LITELINKTM uses advanced optical signal coupling techniques to provide the required electrical isolation between the telephone and the Customer Premises Equipment (CPE). The LITELINKTM differs from other solutions using optical or capacitive isolation techniques by including the barrier inside the IC package, thus eliminating the need for external optocouplers or high-voltage capacitors in the data path resulting in overall reduced board space. The LITELINKTM has been designed to meet or exceed the requirements of international regulatory agencies. For international PTT compliance external passive components can be changed to meet different country requirements. For added flexibility, a second device, the CPC5601, can be used in conjunction with the CPC5604 to offer a host programmable solution. The CPC5601 is programmed serially through the host’s microcontroller. Using the CPC5601 along with the CPC5604 eliminates the need to change external passive components allowing for a flexible, fully international DAA. Ring Detection via Snoop Circuit While in the on-hook state (OH deasserted), an internal multiplexer turns on a “snoop” circuit that actively monitors the phone line for two conditions: incoming ring signal and Caller ID (CID) information. The snoop circuit “snoops” the line continuously while drawing a low 2uA max. current from the telephone line thus meeting regulatory requirements. When the central office (CO) places a ring signal on the telephone line, 90VRMS max, the RING output is pulsed from High to Low for 2 seconds at the same frequency as the AC signal, typically 20Hz, and restored to High during the 4 second delay. The ring detection circuitry is designed to reject false signaling from pulse dialing circuits or noise on the line. the host asserts the CID line which automatically couples the snoop circuit to the RX outputs on the LITELINKTM. After the CID signal is processed by the host, the host will deactivate the CID signal. At this point the host can answer the call by asserting the OH signal. Note that when the LITELINKTM goes off-hook it automatically disconnects the snoop path from both RX and RING outputs. Signals appearing on the telephone line are now coupled through the optical isolation barrier in the LITELINKTM and not via the snoop path. Hook Switch Control The OH or off-hook input is used to place the DAA on or off-hook. When the input is High, the DAA is on-hook or ready to receive calls from the CO. In this mode the snoop circuitry is enabled as described above. Driving OH Low places the DAA off-hook allowing the CO supplied loop current to flow (120mA max.), indicating the DAA is answering or preparing to place a call. Transmit Signal Outgoing analog signals to be transmitted to the telephone lines are placed differentially on the TX+ and TXinputs of the CPC5604. Transmit level from the user device is limited to 0dBm or 2.1Vp-p. The differential transmit signal is converted to a single ended signal by the CPC5604. The transmit signal is transferred across an optical barrier by an electrical-optical-electrical amplifier, which is transparent to the user. Variations in gain due to electrical-optical-electrical efficiency are virtually eliminated by an on-chip automatic gain control circuit which sets the input to output gain of the photodiode amplifier to 1. This results in a TX insertion loss of +/- 1dB. Caller ID (CID) Detection via Snoop Circuit CID is a service offered by the telephone company to provide caller information (i.e. the caller’s telephone number) to the called party. The CID signal is present on the telephone line after the first ring burst is sent from the CO. After this first ring burst is detected by the host, XXX www.clare.com 15 CPC5604 Receive Signal Path (Refer to Block Diagram) Transmit Signal Path (Refer to Block Diagram) Signals to and from the telephone line to the LiteLinkTM appear on Tip and Ring connections. The receive signal is extracted from the transmit signal via the 2-4 wire hybrid block. The receive signal is then converted to infrared light by the receive photodiode amplifier and LED front end. The intensity of the infrared light is modulated by the receive signal and this light is transferred across the electrical isolation barrier via reflective dome to a photodiode where the light is converted to a photocurrent. This photocurrent is a highly linear representation of the receive signal and is amplified and converted to a voltage. This single ended voltage is converted to a differential voltage signal where it is presented as RX+ and RXand connects to the receive inputs of the host data pump. Signals that are to be sent from the host to the telephone line are placed differentially on TX+ and TX-. The maximum value of the transmit signal should not exceed 0dBm or 2.18Vpp. The differential transmit signal is converted to a single ended signal by the LiteLinkTM. This signal is coupled to the transmit photodiode amplifier in a similar manner to the receive path. Variations in gain due to quantum efficiency of the optics are virtually eliminated by an on chip AGC circuit which automatically sets the input to output gain of the photoamplifier to unity. This means that the receive signal on the telephone line is faithfully reproduced at the RX outputs in terms of amplitude to within 2dB of the received signal. Distortion at the RX outputs is -80dB maximum at a receive level of -3dB over the band of 30Hz-4kHz. At the output of this amplifier the voltage signal is coupled to a voltage to current converter via a transconductance stage where the transmit signal modulates the telephone line loop current. As in the receive stage, the gain of the transmit photodiode amplifier is set to unity automatically thereby limiting insertion loss to 0±1dB. Figures 2C and 2D illustrate connection to the host differentially and single ended respectively. Figure 2B Connection To Host Single Ended (Receive) CPC5604A LITELINKTM HOST DATA PUMP/CODEC 0.1uF Single supply operation requires that the RX outputs be biased at 2.5V DC, therefore, it is necessary to use 0.1uf blocking capacitors for coupling the receive signal to the host.

Incoming ring signal 2. Caller ID information Care should be taken when using this equation since RRXF (R3), CS (C6 or C7), and RSNOOP (R5 or R6) affect receive gain and Caller ID gain. It is recommended that RRXF (R3) be set to the typical value and then after adjusting the ring detect threshold, check that CID gain is acceptable. Caller ID Detection Figure 2D Connection To Host Single Ended (Transmit) Caller ID (CID) is a service offered by the telephone company to provide caller information (i.e. caller’s telephone number) to the called party. CID service is optional and signals only appear on the telephone lines of subscribers that pay for this feature. The CID information appears on the telephone line after the first ring burst is sent from the central office (CO). CPC5604A LITELINKTM HOST DATA PUMP/CODEC 0.1uf TXA1 TXA2 0.1uf TX- TX+ - Some of the characteristics of the CID signal are summarized below: + SINGLE ENDED CONNECTION TO CPC5604A The Snoop circuit “snoops” the line continuously while the LiteLinkTM is in the on-hook mode. Current taken from the telephone line in the on-hook condition by the LITELINKTM is maintained at a low 2uA maximum thus meeting regulatory requirements for minimum on-hook impedance limitation. When the central office places the ring signal on the telephone line, that signal is coupled through a pair of RC circuits to a differential amplifier in the LiteLinkTM. Referring to Block Diagram, snoop capacitors connected to the SNP1/SNP2 pins provide a high voltage isolation barrier between the host and the telephone line while coupling the AC signals to the snoop amplifier. The ring signal is digitized and brought out to the RING pin where the host can qualify it as a valid ring signal. The ring detection threshold is dependent on the values of 3 external components: RRXF (R3), RSNOOP (R5 or R6), and CS (C6 or C7). The default values in the typical bill of materials reflects the parameters in the data sheet for typical operation. If it is desired to change the threshold, the values can be selected by using the equation: VRING(PEAK) = 330E-3 5RRXF Parameter Value Signal Level Link Type Transmission Scheme Logical 1 (mark) Logical 0 (Space) Transmission Rate Data BER Bit Duration -13dBm Simplex, 2W Phase-coherent, FSK 1200±12Hz 2200± 22Hz 1200bps serial binary async < 10E -5 833±50uS (same for start/stop as well) Full details about the CID signal can be found in Bellcore document TR-TSY-000030, issue 1/1988.

The pins that control the VI characteristics and current limiting are designated ZDC and DCS. Meeting DC requirements are achieved by selecting the appropriate resistors RZDC (R16) and RDCS (R20) respectively. Resistor values can also be switched in and out with the CPC5601device or optocouplers which enables international compliance under software control. Suggested resistor values for various countries are listed in table 1. The VI profile on Tip and Ring is described by the following equation: CID VLINE = VBRIDGE + This CID signal is then processed by the host and, after processing, the host will deactivate the CID signal. At this point the host can answer the call if desired by asserting the OH pin on the LiteLinkTM. It’s important to note that when the LiteLinkTM goes off-hook, it automatically disconnects the snoop path from both the RX and Ring outputs. Signals appearing on the telephone line are now coupled through the optical isolation barrier in the LiteLinkTM and not via the capacitors in the snoop path. RDCS+12MΩ (RDCS) 0.5V+ (ILINE - 8mA)RZDC Example: ILINE = 20mA, VBRIDGE = 1.2V, RDCS = 1.69MW, RZDC = 8W, VLINE = 6.0V.

This implies that the snoop frequency response is 600Hz. Gain is expressed in decibels by: 18 www.clare.com XXX CPC5604 Figure 4 On-Hook DC Resistance Tip/Ring Setup TIP A + TM LITELINK DAA Circuit - 100VDC RING On-Hook Resistance CTR-21 Compliance Figure 4 shows the test setup for on-hook DC resistance. The battery is set to 100VDC and an ammeter is placed in series with the battery connection. When the DAA is in the on-hook state, the leakage current is obtained and then the battery voltage is divided by this current yielding the on-hook resistance. The LiteLinkTM is guaranteed to have a leakage current < 10uA at 100V which is equivalent to an on-hook resistance > 10MΩ thus meeting regulatory approvals. CTR-21 is the standard for connection of data communications equipment to the European telephone network. The maximum current limit requirement in CTR-21 (Section 4.7.1) is 60mA and can be selected by the following equation: Current Limiting The LiteLinkTM includes a current limiting feature that is selectable via resistor RZDC (R16). The current limit value is set by the equation: 10 1V 1V RZDC + 8mA Clare recommends current limit be set to 53mA using an RZDC value of 22Ω. Since VDD is regulated to +3.5V, excess power is dissipated in the external MOSFET package. Since the maximum off-hook line voltage and current in CTR-21 is 40V and 53mA respectively, the maximum power dissipated by the MOSFET is approximately 2.1W. 12 RZDC AC Characteristics For US/Canada/Japan the recommended value for RZDC (R16) is 8Ω which yields a current limit value of 133mA. The current limiting feature is especially useful in the case where the host system is inadvertently connected to a digital PBX telephone port which usually has a very high current limit value. The current limiting capability will prevent damage to the LiteLinkTM in this scenario. XXX ILM = In a similar manner to the DC characteristics, AC termination impedance is set via RZNT (R18). For all applications, a 604W resistor for RZNT (R18) is required to reflect 600W to the CO. www.clare.com 19 CPC5604 Differential and Single Ended Mode The LiteLinkTM is designed to support either differential or single ended signals on Tx and/or Rx pins. The decision of which topology to use is based on the particular chipset being used to drive the LiteLinkTM. For example, most Lucent modem chips require both differential receive and transmit ability, while most Rockwell devices require differential transmit and single ended receive. The LiteLinkTM supports a full 0dBm differential signal on its Tx inputs.

Snoop mode operation requires that the DAA be in — the on-hook state and the CID pin asserted (driven Low).

Spacing of 0.1” should be maintained between traces on the phone line side. If possible, traces should be routed away from large 60Hz fields to prevent noise inducement into the snoop circuit. As a practical matter, CMRR is dependent on how well the external snoop network CS and RSNOOP are matched. It is recommended that capacitors CS (C6 or C7) be ceramic NPO (COG) type for excellent temperature stability and have a tolerance of 5% or less. Resistor tolerance for RSNOOP (R5 or R6) should also be at least 5% or better. Figure 10A shows the test setup for CMRR through the snoop signal path. For this test the LITELINKTM is onhook and the frequency is swept from 20Hz to 4kHz. Figure 10B is a graph of CMRR vs. frequency.
