1. The Si2457/34/15/04 specifications are guaranteed when the typical application circuit (including component tolerance)
2. All minimum and maximum specifications are guaranteed and apply across the recommended operating conditions.
3. The digital supply, VD, operates from 3.0 to 3.6 V.
1. ILIM = U67, bit 9; DCV = U67, bits 3:2; MINI = U67, bits 13:12; DCR = U67, bit 7; RT = U67, bit 0.
2. The ring signal is guaranteed to not be detected below the minimum. The ring signal is guaranteed to be detected
3.0 to 3.6 V, T
