SI3014-KS Présentation
A direct-access arrangement, or DAA, is a telephone-line interface device that places a codec and line-side transceiver behind a digital host interface. In the broader hierarchy, the SI3014-KS belongs to interface ICs, telecom line interfaces, modem ICs, and semiconductor ICs. Its MC-97 architecture helps a host codec control the digital and analog telephone-line signal path while the integrated isolation barrier separates host-side circuitry from line-side circuitry.
The verified data identifies the SI3014-KS as a primary or secondary codec interface that is compliant with FCC, CTR21, JATE, and other PTT requirements. Its 84 dB dynamic-range TX/RX paths support voice-quality signal handling. Operation from a 5 V supply and compatibility with 3.3 V-related product information may be useful in mixed-voltage telecom designs, but circuit-specific voltage limits must be confirmed against the manufacturer datasheet before implementation.
The device uses ASK over home power lines as its listed data format, while additional source material identifies it as a global MC-97 silicon DAA for telephone and modem interfaces. These descriptions place it between a digital audio codec and an analog phone line, with isolation helping control fault energy and common-mode coupling. Users should account for the non-RoHS and contains-lead status stated in the verified distributor data when evaluating regulatory and assembly requirements.
Typical uses include legacy caller-ID, fax, answering-machine, voice-mail, modem, PBX, and embedded telephone equipment. In these systems, the MC-97 interface can connect a host processor to the line-side transceiver while the AC97 link carries digital audio and control traffic. Existing equipment may also use the SSI interface described in distributor listings, although the exact supported interface configuration must be checked against the original system design.
Designers should not treat the isolated line interface as a universal drop-in replacement without reviewing the pinout, supply rails, clocking, impedance, isolation, and regulatory circuit requirements. The verified data identifies the part as not recommended for new designs and points users toward the Si3018 datasheet, so lifecycle and sourcing checks are essential. This page combines the verified specifications, sourcing records, and practical constraints without inventing undocumented electrical values.

Applications typiques
SI3014-KS convient pour 6 applications: Legacy Caller-ID Equipment, Voice Mail and Answering Machines, Legacy Fax Interfaces, PBX and Voice-Card Assemblies, Home Power-Line Communication Equipment, Embedded Modem Platforms.
Legacy Caller-ID Equipment
The SI3014-KS fits legacy caller-ID hardware that already uses an MC-97 direct-access-arrangement architecture. Its verified AC97 2.1 interface provides a digital host connection, while the isolated global phone-line interface and 84 dB TX/RX dynamic range support voice-band signal handling. Because the part is listed as not recommended for new designs, it is most appropriate for repair and sustainment. Confirm the original codec pinout, clocking, isolation boundary, and country-specific PTT requirements before substitution.
Recommandé
Voice Mail and Answering Machines
The SI3014-KS can support a voice-mail or answering-machine design that needs a dedicated telephone-line interface beside a digital audio codec. The verified AC97 2.1 compliance gives the host side a defined codec connection, and the 84 dB TX/RX dynamic range is appropriate for voice-band paths. Its greater-than-3000 V isolation specification helps define the host-to-line separation. Validate audio levels, ring detection, hook-switch behavior, and regulatory network requirements against the complete design.
Recommandé
Legacy Fax Interfaces
For an existing fax interface based on MC-97 silicon DAA technology, the SI3014-KS can sit between host circuitry and the phone line. The verified 5 V supply, 16-SOIC package, and AC97 2.1 interface make it relevant to established designs that match its electrical and mechanical assumptions. It should not be selected for a new fax platform solely from this page because the manufacturer-related distributor result says it is not recommended for new designs. Check timing, line impedance, isolation, and signaling compatibility first.
Recommandé
PBX and Voice-Card Assemblies
The SI3014-KS is applicable to older PBX or voice-card assemblies that use an isolated global phone-line interface and a host codec. The verified AC97 2.1 interface, 5 V supply, and greater-than-3000 V isolation provide the principal design anchors. In a multi-line card, placement, isolation spacing, grounding, and channel-to-channel crosstalk are critical; those layout values are not supplied and must come from the manufacturer documentation. Use the part for maintenance rather than as an unqualified new-design choice.
Recommandé
Home Power-Line Communication Equipment
The verified listing identifies ASK over home power lines as the SI3014-KS data format, making it relevant to legacy home-power-line communication equipment that integrates a telephone-line or modem-related interface. The MC-97 DAA architecture and AC97 2.1 compliance can connect the host controller to the line-side circuitry. Engineers should verify the actual modulation, isolation, supply sequencing, and regulatory architecture in the original system; the available data does not provide a complete power-line transceiver specification.
Recommandé
Embedded Modem Platforms
The SI3014-KS can support a legacy embedded modem platform when the host processor expects an MC-97 DAA and AC97 2.1 signaling. Its 84 dB TX/RX dynamic range and isolated line-side interface are useful for voice and modem signal paths, while the 16-SOIC package supports conventional surface-mount assembly. The 3.3 V and 5 V references in distributor listings require confirmation against the actual schematic. Because the device is not recommended for new designs, new modem products should begin with the Si3018 guidance.

Notes de conception
Do not substitute the SI3014-KS solely because a distributor labels another part as a modem or line-interface IC. The verified data identifies a specialized global MC-97 DAA with AC97 2.1 behavior, a 5 V supply, and greater-than-3000 V isolation. A valid replacement must also preserve the 16-SOIC footprint, pin functions, clocking, isolation boundary, line-side behavior, and country-specific PTT requirements. The supplied cross-reference search found no verified pin-compatible alternatives.
Preserve the isolation barrier and follow the manufacturer layout guidance when placing the SI3014-KS. The available evidence specifies greater-than-3000 V isolation but does not provide creepage, clearance, pad geometry, or isolation-capacitor values. Do not infer those dimensions from the 16-SOIC body width. Use the official package drawing and application guidance, then verify the assembled board against the applicable telecom safety and regulatory requirements.
Treat the listed 5 V supply as the verified supply value, but confirm the exact operating and absolute-maximum limits in the manufacturer datasheet. Distributor listings also mention 3.3 V information, which may describe related interface rails or product metadata rather than a complete operating range. Check sequencing, decoupling, ground separation, and line-side power requirements against the original schematic before applying power.
Review AC97 clocking and signal timing in the complete host design. The supplied data confirms AC97 2.1 compliance and 84 dB TX/RX dynamic range, but it does not provide edge rates, clock tolerances, audio impedance, or channel crosstalk. Preserve the intended host-to-DAA partitioning, route sensitive clock and audio lines away from isolation and telephone-line transient paths, and validate the final board with the manufacturer's test guidance.
Informations de conformité
Verified distributor data identifies the SI3014-KS as RoHS non-compliant and containing lead. FCC, CTR21, JATE, and other PTT compatibility are listed as device features or intended regulatory context, but final product compliance is not established by the supplied data. REACH, halogen-free status, and conflict-minerals status are unknown.
