HC-5504B
Data Sheet July 2004 FN2886.8
EIA/ITU PABX SLIC with 40mA Loop Feed
The Intersil SLIC incorporates many of the BORSHT functions on a single IC chip. This includes DC battery feed, a ring relay driver, supervisory and hybrid functions. This device is designed to maintain transmission performance in the presence of externally induced longitudinal currents. Using the unique Intersil dielectric isolation process, the SLIC can operate directly with a wide range of station battery voltages. The SLIC also provides selective denial of power. If the PBX system becomes overloaded during an emergency, the SLIC will provide system protection by denying power to selected subscriber loops. The Intersil SLIC is ideally suited for the design of new digital PBX systems by eliminating bulky hybrid transformers.

HC-5504B Pin Descriptions
24 PIN SOIC 1 SYMBOL TIP DESCRIPTION An analog input connected to the TIP (more positive) side of the subscriber loop through a 150 feed resistor and a ring relay contact. Functions with the Ring terminal to receive voice signals from the telephone and for loop monitoring purposes. An analog input connected to the RING (more negative) side of the subscriber loop through a 150 feed resistor and a ring relay contact. Functions with the Tip terminal to receive voice signals from the telephone and for loop monitoring purposes. Senses ring side of loop for ground key and ring trip detection. During ringing, the ring signal is inserted into the line at this node and RF is isolated from RFS via a relay. Positive Voltage Source - Most positive supply. VB+ is typically 12V or 5V. Capacitor #3 - An external capacitor to be connected between this terminal and analog ground. Required for proper operation of the loop current limiting function, and for filtering VB-. Typical value is 0.3F, 30V. Digital Ground - To be connected to zero potential and serves as a reference for all digital inputs and outputs on the SLIC microcircuit. Ring Synchronization Input - A TTL-compatible clock input. The clock should be arranged such that a positive pulse transition occurs on the zero crossing of the ring voltage source, as it appears at the RFS terminal. For Tip side injected systems, the RS pulse should occur on the negative going zero crossing and for Ring injected systems, on the positive going zero crossing. This ensures that the ring relay activates and deactivates when the instantaneous ring voltage is near zero. If synchronization is not required, the pin should be tied to 5V. Relay Driver - A low active open collector logic output. When enabled, the external ring relay is energized. Tip Feed - A low impedance analog output connected to the TIP terminal through a 150 feed resistor. Functions with the RF terminal to provide loop current, feed voice signals to the telephone set, and sink longitudinal current. Ring Feed - A low impedance analog output connected to the RING terminal through a 150 feed resistor. Functions with the TF terminal to provide loop current, feed voice signals to the telephone set, and sink longitudinal current. Negative Voltage Source - Most negative supply. VB- is typically -48V with an operational range of -42V to -58V. Frequently referred to as "battery". Battery Ground - To be connected to zero potential. All loop current and some quiescent current flows into this ground terminal. Switch Hook Detection - A low active LS TTL - compatible logic output. This output is enabled for loop currents exceeding 10mA and disabled for loop currents less than 5mA. Ground Key Detection - A low active LS TTL - compatible logic output. This output is enabled if the DC current into the ring lead exceeds the DC current out of the tip lead by more than 20mA, and disabled if this current difference is less than 10mA. Power Denial - A low active TTL - Compatible logic input. When enabled, the switch hook detect (SHD) and ground key detect (GKD) are not necessarily valid, and the relay driver (RD) output is disabled. Ring Command - A low active TTL - Compatible logic input. When enabled, the relay driver (RD) output goes low on the next high level of the ring sync (RS) input, as long as the SLIC is not in the power denial state (PD = 0) or the subscriber is not already off- hook (SHD = 0). Capacitor #2 - An external capacitor to be connected between this terminal and digital ground. Prevents false ground key indications from occurring during ring trip detection. Typical value is 0.15F, 10V. This capacitor is not used if ground key function is not required and (Pin 17) may be left open or connected to digital ground. The analog output of the spare operational amplifier. The output voltage swing is typically 5V. The inverting analog input of the spare operational amplifier. The non-inverting analog input of the spare operational amplifier.

24 PIN SOIC 21 SYMBOL RX (Continued)
DESCRIPTION Receive Input, 4-Wire Side - A high impedance analog input which is internally biased. Capacitive coupling to this input is required. AC signals appearing at this input differentially drive the Tip feed and Ring feed terminals, which in turn drive tip and ring through 300 of feed resistance on each side of the line. Capacitor #4 - An external capacitor to be connected between this terminal and analog ground. This capacitor prevents false ground key indication and false ring trip detection from occurring when longitudinal currents are induced onto the subscriber loop from near by power lines and other noise sources. This capacitor is also required for the proper operation of ring trip detection. Typical value is 0.5F, to 1.0F, 20V. This capacitor should be nonpolarized. Analog Ground - To be connected to zero potential and serves as a reference for the transmit output (TX) and receive input (RX) terminals. Transmit Output, 4-Wire Side - A low impedance analog output which represents the differential voltage across Tip and Ring. Transhybrid balancing must be performed (using the SLIC microcircuit's spare op amp) beyond this output to completely implement two to four wire conversion. This output is unbalanced and referenced to analog ground. Since the DC level of this output varies with loop current, capacitive coupling to the next stage is essential. No internal connection.

Typical Component Values
C2 = 0.15F, 10V. C3 = 0.3F, 30V. C4 = 0.5F to 1.0F, 10%, 20V (Should be nonpolarized). C5 = 0.5F, 20V. C6 = C7 = 0.5F (10% Match Required) (Note 7). C8 = 0.01F, 100V. C9 = 0.01F, 20V, 20%.
NOTES: 5. Secondary protection diode bridge recommended is a 2A, 200V type. 6. To obtain the specified transhybrid loss it is necessary for the three legs of the balance network, C6-R1 and R2 and C7-ZB-R3 , to match in impedance to within 0.3%. Thus, if C6 and C7 are 1F each, a 20% match is adequate. It should be noted that the transmit output to C6 sees a -22V step when the loop is closed. Too large a value for C6 may produce an excessively long transient at the op amp output to the PCM Filter/CODEC. A 0.5F and 100k gives a time constant of 50ms. The uncommitted op amp output is internally clamped to stay within 6.6V and is current limited. 7. All grounds (AG, BG, and DG) must be applied before VB+ or VB-. Failure to do so may result in premature failure of the part. If a user wishes to run separate grounds off a line card, the AG must be applied first. 8. Application shows Ring Injected Ringing, Balanced or Tip injected configuration may be used. 9. Pin numbers given for SOIC package.
R1 = R2 = R3 = 100k (0.1% Match Required, 1% absolute value) ZB = 0 for 600 Terminations (Note 7). RB1 = RB2 = RB3 = RB4 = 150 (0.1% Match Required, 1% absolute value). RS1 = RS2 =1k, typically. CS1 = CS2 = 0.1F, 200V typically, depending on VRING and line length. Z1 = 150V to 200V transient protection. PTC used as ring generator ballast.
