TYPICAL COMPONENT VALUES
C1 = 0.5µF, 30V
RF1 = RF2 = 210kâ¦, 1%
CF1 = CF2 = 0.22µF, 10%, 20V Nonpolarized
C3 = 0.01µF, 100V, ±20%
C4 = 0.01µF, 100V, ±20%
C5 = 0.01µF, 100V, ±20%
CAC = 0.5µF, 20V
KZ0 = 30kâ¦, (Z0 = 600â¦)
RL1, RL2; Current Limit Setting Resistors:
ILIMIT = (0.6) (RL1 + RL2)/(200 x RL2), RL1 typically 100kâ¦
KRF = 20kâ¦
RB1 = RB2 = RB3 = RB4 = 50⦠0.1% absolute matching
RS1 = RS2 = 1k⦠typically
CS1 = CS2 = 0.1µF, 200V typically, depending on VRing and
line length.
Z1 = 150V to 200V transient protector. PTC used as ring
generator ballast.
NOTES:
1. All grounds (AG, BG) 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.
2. Application shows Ring Injected Ringing, a Balanced or Tip injected configuration may be used.
