Data Sheet HC5513 October 1998 File Number 3963.10 TR909 DLC/FLC SLIC with Low Power Standby The HC5513 is a subscriber line interface circuit which is interchangeable with Ericsson’s PBL3764 for distributed central ofﬁce applications. Enhancements include immunity to circuit latch-up during hot plug and absence of false signaling in the presence of longitudinal currents. The HC5513 is fabricated in a High Voltage Dielectrically Isolated (DI) Bipolar Process that eliminates leakage currents and device latch-up problems normally associated with Junction Isolated (JI) ICs. The elimination of the leakage currents results in improved circuit performance for wide temperature extremes. The latch free beneﬁt of the DI xxprocess guarantees operation under adverse transient conditions. This process feature makes the HC5513 ideally suited for use in harsh outdoor environments.

This is accomplished by using an external op amp (usually part of the CODEC) and by the inversion of the signal from the 4-wire receive port (RSN) to the 4-wire transmit port (VTX). Figure 17 shows the transhybrid circuit. The input signal will be subtracted from the output signal if I1 equals I2. Node analysis yields the following equation: R-V----TT----XX-- + -V--Z--R--B--X-- = 0 (EQ. 21) The value of ZB is then: ZB = –RTX • V-V----RT----XX-- Where VRX/VTX equals 1/ A4-4. Therefore: ZB = RTX • Z---Z-R---T--X- • -1-------Z0------0--T-----Z-0----L--+---+--2---2R----R-F---F--+-----Z---L-- (EQ. 22) (EQ. 23) Example: Given: RTX = 20kΩ, ZRX = 280kΩ, ZT = 562kΩ (standard value), RF = 20Ω and ZL= 600Ω, The value of ZB = 18.7kΩ.

TRANSHYBRID CIRCUIT Supervisory Functions The loop current, ground key and the ring trip detector outputs are multiplexed to a single logic output pin called DET. See Table 1 to determine the active detector for a given logic input. For further discussion of the logic circuitry see section titled “Digital Logic Inputs”. Before proceeding with an explanation of the loop current detector, ground key detector and later the longitudinal impedance, it is important to understand the difference between a “metallic” and “longitudinal” loop currents. Figure 18 illustrates 3 different types of loop current encountered. Case 1 illustrates the metallic loop current. The deﬁnition of a metallic loop current is when equal currents ﬂow out of tip and into ring. Loop current is a metallic current. Cases 2 and 3 illustrate the longitudinal loop current. The deﬁnition of a longitudinal loop current is a common mode current, that ﬂows either out of or into tip and ring simultaneously. Longitudinal currents in the on-hook state result in equal currents ﬂowing through the sense resistors R1 and R2 (Figure 18). And longitudinal currents in the off- hook state result in unequal currents ﬂowing through the sense resistors R1 and R2. Notice that for case 2, longitudinal currents ﬂowing away from the SLIC, the current through R1 is the metallic loop current plus the longitudinal current; whereas the current through R2 is the metallic loop current minus the longitudinal current. Longitudinal currents are generated when the phone line is inﬂuenced by magnetic ﬁelds (e.g., power lines). Loop Current Detector Figure 18 shows a simpliﬁed schematic of the loop current and ground key detectors. The loop current detector works by sensing the metallic current ﬂowing through resistors R1 and R2. This results in a current (IRD) out of the transconductance ampliﬁer (gm1) that is equal to the product of gm1 and the metallic loop current. IRD then ﬂows out the RD pin and through resistor RD to VEE. The value of IRD is equal to: IRD = --I--T----I-P-----6–---0--I-0-R----I--N----G---- = 3---I-0-L--0-- (EQ. 24) The IRD current results in a voltage drop across RD that is compared to an internal 1.25V reference voltage. When the voltage drop across RD exceeds 1.25V, and the logic is conﬁgured for loop current detection, the DET pin goes low. The hysteresis resistor RH adds an additional voltage effectively across RD, causing the on-hook to off-hook threshold to be slightly higher than the off-hook to on-hook threshold. Taking into account the hysteresis voltage, the typical value of RD for the on-hook to off-hook condition is: RD = I--O-----N-----–----H----O-----O----K----4--t-6-o---5--O-----F---F-----–----H----O----O-----K-- (EQ. 25) Taking into account the hysteresis voltage, the typical value of RD for the off-hook to on-hook condition is: RD = I--O-----F----F----–----H----O-----O----K-3---7--t--5o-----O-----N-----–----H----O----O-----K-- (EQ. 26) 64 11 Page
