Note 1: This design targets two basic builds:
- An FCC and JATE compliant design using the
Si3036 chipset.
- A worldwide design using the Si3038 chipset.
Note 2: R12, R13 and C14 are only required if
complex AC termination is used (ACT bit = 1).
Note 3: See "Billing Tone Detection" section for
optional billing tone filter (Germany, Switzerland,
South Africa).
Note 4: See Appendix A for applications requiring
UL 1950 3rd edition compliance.
Note 5: For Si3036 designs R29 is populated with
a 0 ohm resistor and R30 is not installed. For
Si3038 designs R29 is not installed and R30 is
populated with a 0 ohm resistor.
