SI3015-FS 概要
An ISOmodem chipset is a semiconductor solution for connecting equipment to public telephone lines. It combines modem signal-processing and telephone-interface functions into one device family, reducing the need for a separate DSP data pump, modem controller, analog front end, isolation transformer, relays, and optocouplers. The SI3015-FS therefore sits within the broader modem IC and telephone-line interface hierarchy rather than serving as a general-purpose communications transceiver.
The verified listing identifies the part as a V.90 modem operating at 2.4 kbit/s and identifies a 16-pin SOIC package. It also reports V.90 data formatting and tube packaging. A secondary technical listing describes the related SI3015-F-FS variant as a V.22bis ISOmodem chipset with error correction, while the family documentation describes programmable line-interface functionality. Detailed electrical ratings, protocol features not present in the supplied data, and pin assignments remain unverified and must be checked against the manufacturer datasheet before design release.
The SI3015-FS is associated with legacy telephone-network equipment, data communications, fax systems, embedded modems, and industrial telephone interfaces. Its integrated ISOmodem architecture can shorten board development by consolidating functions that would otherwise occupy multiple discrete or integrated blocks. The 16-SOIC package is also straightforward to route on a through-hole PCB and can be assembled using conventional leaded-package processes.
Designers must confirm country-specific line-interface requirements, isolation boundaries, ring detection, hook-switch control, impedance matching, and firmware compatibility before deployment. Do not assume that a distributor category label constitutes proof of regulatory approval. The supplied evidence also does not establish the target part's lifecycle status, pinout, absolute maximum ratings, or complete compliance declarations.
This page consolidates the verified SI3015-FS product, package, protocol, sourcing, and datasheet information into an engineering-oriented record. Where evidence is insufficient, it explicitly identifies missing data rather than estimating electrical values or proposing unverified pin-compatible replacements. Compare the exact ordering code, datasheet revision, and line-interface schematic before substituting any related SI30xx or Si24xx device.

主な用途
SI3015-FS の用途: 6 件s: Legacy Telephone-Line Data Equipment, Embedded Modem Data Terminal, Industrial Telephone Monitoring Unit, Fax-System Data Interface, Remote Diagnostics and Service Link, Data Communication Test Fixture.
Legacy Telephone-Line Data Equipment
The SI3015-FS is associated with 2.4 kbit/s V.90 modem communications, making it a candidate for legacy telephone-line equipment where the system must preserve an established modem mode. Its Si2400 ISOmodem family context provides a programmable line interface and integrated DAA concept that can reduce discrete telephone-interface circuitry. Before design use, engineers must verify the exact SI3015-FS line-side electrical limits, isolation architecture, impedance requirements, and national network approvals; those values are not supplied in the current evidence.
Embedded Modem Data Terminal
A terminal or embedded controller requiring a 2.4 kbit/s V.90 connection can potentially use the SI3015-FS when its host interface and telephone-line parameters match the system. The verified 16-SOIC package supports conventional assembly and inspection, but no host-interface pins or logic levels are exposed in the supplied excerpts. The design should therefore treat the processor bus, UART or parallel interface, reset behavior, clocking, and firmware protocol as mandatory pre-layout checks against the exact manufacturer datasheet.
Industrial Telephone Monitoring Unit
The SI3015-FS may fit an industrial monitoring product that uses a switched telephone network as an alternate communications path. Its 2.4 kbit/s V.90 identification is relevant for compatibility with legacy endpoints, while the ISOmodem family's integrated line-interface concept can simplify board partitioning. However, industrial suitability cannot be confirmed from the provided data: temperature range, ESD performance, isolation rating, surge immunity, watchdog behavior, and lifecycle status remain unavailable and require documentary validation.
Fax-System Data Interface
A legacy fax or multifunction-peripheral subsystem may need a modem data path capable of V.90 operation at 2.4 kbit/s. The SI3015-FS is functionally relevant to that architecture because the verified listing identifies both the protocol format and nominal rate. Actual interchange with a specific fax controller depends on unverified details such as supported compression, error correction, call-progress behavior, framing, and host commands. Those capabilities must not be inferred from the part number or family description alone.
Remote Diagnostics and Service Link
Remote diagnostics equipment can use a telephone modem path where network infrastructure and endpoint compatibility favor legacy V.90 operation. The SI3015-FS's 2.4 kbit/s rate provides a defined nominal data speed for configuration exchange, status reporting, and firmware transfer when application traffic permits. Deployment still requires verification of line conditioning, ring and hook behavior, call-progress signaling, security policy, and unattended-restart requirements because none of these operating details is present in the verified excerpts.
Data Communication Test Fixture
A communications test fixture intended to reproduce a 2.4 kbit/s V.90 endpoint can potentially use the SI3015-FS to exercise software, cabling, and line-interface interoperability. The 16-SOIC package is convenient for fixture boards and replacement from tubes. For meaningful test coverage, confirm the modem's exact line-side impedance, transmit and receive levels, timeout behavior, and supported country-line profiles. The available evidence supports protocol identification and package identity, but not calibration values or test limits.

主な差別化要因

設計ノート
Do not treat SI3015-F-FS evidence as automatically applicable to SI3015-FS. The supplied search results associate the two ordering codes with different distributor records, while the visible $2.9203 LCSC price and in-stock statement explicitly belong to SI3015-F-FS. Before purchasing or substituting, compare the complete manufacturer ordering table, package suffix, pinout, and approved-part status. This prevents a similar suffix from causing an unplanned procurement or qualification error.
Design the telephone-line section as a potentially high-voltage, high-impedance isolation domain only after the exact SI3015-FS datasheet establishes its integrated DAA boundaries. Keep the modem, connector, protection network, and line-side routing segregated according to the manufacturer reference layout. Do not guess creepage, clearance, surge components, or isolation values from the family description; use exact schematic and layout guidance before copper routing and safety review.
The verified evidence does not expose the target pinout, supply range, current consumption, or host interface. Therefore, footprint creation based solely on a generic SOIC-16 library drawing is insufficient. Obtain the exact package drawing and pin table, confirm exposed or missing connections, and verify every net against the schematic before fabrication. Although the package is a 16-SOIC, correct body width, lead pitch, and solder footprint must still come from controlled documentation.
コンプライアンス情報
A secondary result for SI3015-F-FS reports lead-free and RoHS status, but the supplied evidence does not establish those declarations for the exact SI3015-FS ordering code. AEC-Q100 is not applicable to this legacy modem interface IC based on the supplied product context, but no automotive qualification claim was provided.
