The Si3216 ProSLIC is the world's first integrated SLIC/codec solution to provide both wideband (50 Hz to 7.0 kHz) and narrowband (200 Hz to 3.4 kHz) audio codec modes for enhanced voice quality in voice-over-IP (VoIP) applications.
The Si3216 delivers high-fidelity voice quality at a fraction of the cost. Like the Si3210, the Si3216 integrates subscriber line interface circuit (SLIC), codec and battery generation functionality into a single low-voltage CMOS integrated circuit. Combined with Silicon Labs' Si3201 linefeed integrated circuit, the Si3216 packs maximum performance and flexibility into a 1.5 in² footprint, making it the smallest single-channel telephony interface available.
The integrated battery supply continuously adapts voltage to minimize power and enables the entire solution to be powered from a single 3.3 V or 5 V supply. Software-configurable features include 5 REN internal ringing up to 90 VPK, dual-tone audio generation and an enhanced set of telephony linefeed and signaling capabilities for global operation with only one hardware solution. The Si3216 is pin-for-pin and software-compatible with the Si3210 and Si3215 ICs.
An application programming interface (API) is available to accelerate and simplify code development.
