1. The Si2400 design survives up to 3500 V longitudinal surges without R27, R28, D3, D4, Z4, and Z5. Adding the R27, R28, D3, D4, Z4,
2. For FCC-only designs: C14, C38, C39, R12, R13, R31, and R32 are not required; L1 and L2 may be replaced with a short; R2 may be
3. If the auto answer, ring detect, and caller ID features are not used, R9, R10, C7, C8, C18, and C19 may be removed. In this case, the
4. C22 and C30 may provide an additional improvement in emissions/immunity and/or voice performance, depending on design and
5. Compliance with EN55022 and/or CISPR-22 conducted disturbance tests requires L1, L2, C38, C39, R31, and R32. See also
6. Several diode bridge configurations are acceptable (suppliers include General Semi., Diodes Inc.).
7. Q4 may require copper on board to meet 1/2 W power requirement. (Contact manufacturer for details.)
8. RV2 can be installed to improve performance for multiple longitudinal surges.
9. The R7, R8, R15, and R16, R17, R19 resistors may each be replaced with a single resistor of 1.78 kΩ, 3/4 W, ±1%. For FCC-only
10. If the parallel phone detection feature is not used, R25 and R26 may be removed.
11. To ensure compliance with ITU specifications, frequency tolerance must be less than 100 ppm including initial accuracy, 5-year aging,
Z5 enhanced lightning option increases longitudinal surge survival to greater than 6600 V. The isolation capacitors C1, C4, C24, and
C25 must also be rated to greater than the surge voltage. Y-class capacitors are recommended for highest surge survival.
±5%; with Z1 rated at 18 V, C5 may be rated at 16 V; also see note 9.
RNG1 and RNG2 pins of the Si3015 should be connected to the IGND pin.
