FIGURE 1. TYPICAL LINE CIRCUIT APPLICATION WITH THE MONOLITHIC SLIC
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%.
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.
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 0.5
F 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.
