26 / 100 page  Si3233 26 Preliminary Rev. 0.5 2.3.6. DC-DC Converter During Ringing When the ProSLIC enters the ringing state, it requires voltages well above those used in the active mode. The voltage to be generated and regulated by the dc-dc converter during a ringing burst is set using the VBATH register (direct Register 74). VBATH can be set between 0 and –94.5 V in 1.5 V steps. To avoid clipping the ringing signal, VBATH must be set larger than the ringing amplitude. At the end of each ringing burst the dc-dc converter switches back to active state regulation as described above. 2.4. Tone Generation Two digital tone generators are provided in the ProSLIC. They allow the generation of a wide variety of single or dual tone frequency and amplitude combinations and spare the user the effort of generating the required POTS signaling tones on the PCM highway. DTMF, FSK (caller ID), call progress, and other tones can all be generated on-chip. 2.4.1. Tone Generator Architecture A simplified diagram of the tone generator architecture is shown in Figure 11. The oscillator, active/inactive timers, interrupt block, and signal routing block are connected to give the user flexibility in creating audio signals. Control and status register bits are placed in the figure to indicate their association with the tone generator architecture. These registers are described in more detail in Table 25. Figure 11.
