Functional Description 2.1 Introduction The CPC7583 has the following states: • Talk. Loop break switches SW1, and SW2 closed, all other switches open. • Ringing. Ringing switches SW3, SW4 closed, all other switches open. • TESTout. Testout switches SW5, SW6 closed, all other switches open. • Ringing generator test. SW7, SW8 closed, all other switches open. • TESTin. Testin switches SW9 and SW10 closed. • Simultaneous TESTin and TESTout. SW9, SW10, SW5, and SW6 closed, all other switches open. • Simultaneous test out and ringing generator test. SW5, SW6, SW7, and SW8 closed, all other switches open (only on the xC and xD versions). • All Off. All switches open. See “Truth Tables” on page 12 for more information. The CPC7583 offers break-before-make and make-before-break switching from the ringing state to the talk state with simple logic level input control. Solid-state switch construction means no impulse noise is generated when switching during ringing cadence or ring trip, eliminating the need for external zero-cross switching circuitry. State-control is via logic-level input so no additional driver circuitry is required. The linear line break switches SW1 and SW2 have exceptionally low RON and excellent matching characteristics. The ringing switch SW4 has a minimum open contact breakdown voltage of 465 V. This is sufficiently high, with proper protection, to prevent breakdown in the presence of a transient fault condition (i.e., passing the transient on to the ringing generator). Integrated into the CPC7583 is an over voltage clamping circuit, active current limiting, and a thermal shutdown mechanism to provide protection to the SLIC device during a fault condition. Positive and negative surges are reduced by the current limiting circuitry and hazardous potentials are diverted to ground via diodes and the integrated SCR. Power-cross potentials are also reduced by the current limiting and thermal shutdown circuits. To protect the CPC7583 from an overvoltage fault condition, the use of a secondary protector is required. The secondary protector must limit the voltage seen at the TLINE and RLINE terminals to a level below the maximum breakdown voltage of the switches. To 14 minimize the stress on the solid-state contacts, use of a foldback or crowbar type secondary protector is recommended. With proper selection of the secondary protector, a line card using the CPC7583 will meet all relevant ITU, LSSGR, TIA/EIA and IEC protection requirements. The CPC7583 operates from a +5 V supply only. This gives the device extremely low idle and active power consumption and allows use with virtually any range of battery voltage. The battery voltage is also used by the CPC7583 as a reference for the integrated protection circuit. In the event of a loss of battery voltage, the CPC7583 enters the all-off state. 2.2 Switch Logic The CPC7583 provides, when switching from the ringing state to the talk state, the ability to control the release timing of the ringing switches SW3 and SW4 relative to the state of the loop break switches SW1 and SW2 using simple logic-level input. This is referred to as a make-before-break or break-before-make operation. When the line break switch contacts (SW1 and SW2) are closed (or made) before the ringing access switch contacts (SW3 and SW4) are opened (broken), this is referred to as make-before-break operation. Break-before-make operation occurs when the ringing access contacts (SW3 and SW4) are opened (broken) before the line break switch contacts (SW1 and SW2) are closed (made). With the CPC7583, the make-before-break and break-before-make operations can easily be selected by applying the proper sequence of logic inputs to INTESTout, INRINGING, and INTESTin. The logic sequences for either mode of operation are given in “Make-Before-Break Operation (Ringing to Talk Transition)” on page 15 and “Break-Before-Make Operation (Ringing to Talk Transition)” on page 15. Logic states and explanations are given in “Truth Tables” on page 12. Break-before-make operation can also be achieved using the TSD pin as an input. In “Break-Before-Make Operation (Ringing to Talk Transition)” on page 15, lines 2 and 3, it is possible to induce the switches to the all-off state by grounding TSD instead of applying input to the logic pins. This has the effect of overriding the logic inputs and forcing the device to the all-off state. For www.clare.com R06 CPC7583 20 Hz ringing hold this input state for 25 ms. During this hold period, toggle the inputs from the ringing state to the talk state. After the 25 ms, release TSD to return switch control to the input pins INTESTout, INRINGING, INTESTin and the latch control pin. 2.2.1 Make-Before-Break Operation (Ringing to Talk Transition) State Ringing INRINGING INTESTIN INTESTOUT 1 0 TSD Timing 0 Floating - SW4 waiting for next zero-current crossing to turn off.

In lines 2 and 3 of the table “Break-Before-Make Operation (Ringing to Talk Transition)” on page 15, instead of using the logic input pins to force the all-off state, force TSD to ground. This overrides the logic inputs and also forces the all off state. Hold this state for one-half of the ringing cycle. During this TSD forced all-off state, change the inputs from the power ringing state (INRING = 1, INTESTIN = 0, INTESTOUT = 0) to the talk state (INRING = 0, INTESTIN = 0, INTESTOUT = 0). After the hold period, release TSD to return switch control to the input pins which will set the talk state. R06 2.4 Data Latch The CPC7583 has an integrated data latch. The latch operation is controlled by logic-level input at the LATCH pin. The data input of the latch are the input pins, while the output of the data latch is an internal node used for state control. When the LATCH control pin is at logic 0, the data latch is transparent and data control signals flow directly through to state control. A change in input will be reflected by a change in switch state. When the LATCH control pin is at logic 1, the data latch is active and a change in input control will not affect switch state. The switches will remain in the position they were in when the LATCH changed from www.clare.com 15 CPC7583 logic 0 to logic 1 and will not respond to changes in input as long as the latch is at logic 1. The TSD input is not tied to the data latch. Therefore, TSD is not affected by the LATCH input and the TSD input will override state control. 2.5 TSD Behavior Setting TSD to +5V allows switch control using the logic inputs. This setting, however, also disables the thermal shutdown circuit and is therefore not recommended. When using logic control via the input pins, TSD should be allowed to float. As a result, the two recommended states when using TSD as a control are 0, which forces the device to an all-off state, or float, which allows logic inputs to remain active. This requires the use of an open-collector type buffer. 2.6 Ringing Switch Zero-Cross Current Turn Off After the application of a logic input to turn SW4 off, the ringing switch is designed to delay the change in state until the next zero-crossing. Once on, the switch requires a zero-current cross to turn off, and therefore should not be used to switch a pure DC signal. The switch will remain in the on state no matter the logic input until the next zero crossing. These switching characteristics will reduce and possibly eliminate overall system impulse noise normally associated with ringing switches. See Clare application note AN-144, Impulse Noise Benefits of Line Card Access Switches for more information. The attributes of ringing switch SW4 may make it possible to eliminate the need for a zero-cross switching scheme. A minimum impedance of 300 Ω in series with the ringing generator is recommended. 2.7 Power Supplies Both a +5 V supply and battery voltage are connected to the CPC7583. Switch state control is powered exclusively by the +5 V supply. As a result, the CPC7583 exhibits extremely low power consumption during both active and idle states. 2.8 Battery Voltage Monitor The CPC7583 also uses the VBAT voltage to monitor battery voltage. If battery voltage is lost, the CPC7583 immediately enters the all-off state. It remains in this state until the battery voltage is restored. The device also enters the all-off state if the system battery voltage goes more positive than –10 V, and remains in the all-off state until the battery voltage goes more negative than –15 V. This battery monitor feature draws a small current from the battery (less than 1 μA typical) and will add slightly to the device’s overall power dissipation. 2.9 Protection 2.9.1 Diode Bridge/SCR The CPC7583 uses a combination of current limited break switches, a diode bridge/SCR clamping circuit, and a thermal shutdown mechanism to protect the SLIC device or other associated circuitry from damage during line transient events such as lightning. During a positive transient condition, the fault current is conducted through the diode bridge to ground via FGND. Voltage is clamped to a diode drop above ground. During a negative transient of 2V to 4V more negative than the voltage source at VBAT, the SCR conducts and faults are shunted to FGND via the SCR or the diode bridge. In order for the SCR to crowbar or foldback, the on voltage (see “Protection Circuitry Electrical Specifications” on page 12) of the SCR must be less negative than the VBAT voltage. If the VBAT voltage is less negative than the SCR on voltage, or if the VBAT supply is unable to source the trigger current, the SCR will not crowbar. For power induction or power-cross fault conditions, the positive cycle of the transient is clamped to a diode drop above ground and the fault current directed to ground. The negative cycle of the transient will cause the SCR to conduct when the voltage exceeds the VBAT reference voltage by two to four volts, steering the fault current to ground. The battery voltage is not used for switch control but rather as a supply for the integrated secondary protection circuitry. The integrated SCR is designed to trigger when the voltage at TBAT or RBAT drops 2 to 4 V below the applied voltage on the VBAT pin. This trigger prevents a fault induced overvoltage event at the TBAT or RBAT nodes. 16 www.clare.com R06 CPC7583 2.9.2 Current Limiting function If a lightning strike transient occurs when the device is in the talk state, the current is passed along the line to the integrated protection circuitry and restricted by the dynamic current limit response of the active switches. During the talk state when a 1000V 10x1000 μS pulse (GR-1089-CORE lightning) is applied to the line though a properly clamped external protector, the current into TLINE or RLINE will be a pulse with a typical magnitude of 2.5 A and a duration of less than 0.5 μs. If a power-cross fault occurs with the device in the talk state, the current is passed though break switches SW1 and SW2 on to the integrated protection circuit and is limited by the dynamic DC current limit response of the two break switches. The DC current limit, specified over temperature, is between 80 mA and 425 mA, and the circuitry has a negative temperature coefficient. As a result, if the device is subjected to extended heating due to power cross fault, the measured current at TLINE or RLINE will decrease as the device temperature increases. If the device temperature rises sufficiently, the temperature shutdown mechanism will activate and the device will enter the all-off state. 2.11 External Protection Elements The CPC7583 requires only over-voltage secondary protection on the loop side of the device. The integrated protection feature described above negates the need for additional protection on the SLIC side. The secondary protector must limit voltage transients to levels that do not exceed the breakdown voltage or input-output isolation barrier of the CPC7583. A foldback or crowbar type protector is recommended to minimize stresses on the CPC7583. Consult Clare’s application note, AN-100, “Designing Surge and Power Fault Protection Circuits for Solid State Subscriber Line Interfaces” for equations related to the specifications of external secondary protectors, fused resistors and PTCs. 2.10 Temperature Shutdown The thermal shutdown mechanism will activate when the device temperature reaches a minimum of 110° C, placing the device in the all-off state regardless of logic input. During thermal shutdown mode, the voltage out of the TSD pin will read 0 V. Normal output of TSD is VDD. If presented with a short duration transient such as a lightning event, the thermal shutdown feature will typically not activate. But in an extended power-cross transient, the device temperature will rise and the thermal shutdown will activate forcing the switches to the all-off state. At this point the current measured into TLINE or RLINE will drop to zero. Once the device enters thermal shutdown it will remain in the all-off state until the temperature of the device drops below the deactivation level of the thermal shutdown circuit. This will permit the device to return to normal operation. If the transient has not passed, current will flow up to the value allowed by the dynamic DC current limiting of the switches and heating will begin again, reactivating the thermal shutdown mechanism. This cycle of entering and exiting the thermal shutdown mode will continue as long as the fault condition persists. If the magnitude of the fault condition is great enough, the external secondary protector could activate and shunt all current to ground. R06 www.clare.com 17 CPC7583 3.

Moisture uptake from atmospheric humidity occurs by diffusion. During the solder reflow process, in which the component is attached to the PCB, the whole body of the component is exposed to high process temperatures. The combination of moisture uptake and high reflow soldering temperatures may lead to moisture induced delamination and cracking of the component. To prevent this, this component must be handled in accordance with IPC/JEDEC standard J-STD-033 per the labeled moisture sensitivity level (MSL), level 1 for the SOIC package, and level 3 for the DFN package. For proper assembly, this component must be processed in accordance with the current revision of IPC/JEDEC standard J-STD-020. Failure to follow the recommended guidelines may cause permanent damage to the device resulting in impaired performance and/or a reduced lifetime expectancy. 3.4 Washing Clare does not recommend ultrasonic cleaning of this part.
