SI2400-KS Übersicht
A V.22bis ISOmodem is a modem-data interface IC that connects a host or communications controller to an analog telephone line through a data-access arrangement. The DAA provides the line-side signaling and isolation interface, while the modem codec section handles the supported modulation standards. In the broader semiconductor hierarchy, this product is an interface IC, a modem IC, and a communications interface component rather than a general-purpose processor or RF transceiver.
The verified feature set emphasizes 2,400 bps V.22bis operation, lower-rate V.21, V.22, V.23, Bell 103, and Bell 212A support, V.25 fast connect, reversing, SIA, and other security protocols. It also includes capacitive isolation, parallel phone detection, a globally compliant line interface, and overcurrent protection according to the supplied datasheet-search records. The 16-SOIC package is identified as approximately 3.90 mm wide in the retrieved specification result.
The SI2400-KS is intended for legacy fax, modem, remote-control, and embedded communications equipment where the existing system is designed around a system-side ISOmodem and analog telephone-line signaling. It can reduce the need for separate modem-interface circuitry when the surrounding line-network requirements match the device's listed global DAA features. Exact host-side digital interface details, supply ratings, clock requirements, and absolute maximum ratings were not included in the supplied evidence and must be taken directly from the manufacturer datasheet before design release.
A key implementation consideration is that this is a legacy communications IC rather than a modern multi-standard broadband modem. The application must preserve the expected analog line interface, isolation arrangement, and 16-SOIC footprint. Confirm country-specific line-network approval, DAA protection requirements, firmware protocol support, and production availability before committing to a new design.

Typische Anwendungen

Legacy Fax Machine Interface
The SI2400-KS fits a legacy fax-machine design that still relies on analog telephone-line signaling and a system-side ISOmodem. Its verified 2.4 kbps V.22bis function, V.21/V.22/V.23 support, Bell 103 and Bell 212A formats, and integrated global DAA make it relevant to older fax equipment that predates broadband modem architectures. The IC would normally sit between the system controller and the analog line interface, with the selected DAA, isolation, and phone-detection implementation completed around it. Because the supplied evidence does not provide exact pin functions or electrical limits, engineers should preserve the original reference circuit and verify supply, timing, and line-network requirements from the manufacturer datasheet.
Empfohlen
Analog Telephone-Line Modem
The SI2400-KS is appropriate for an analog telephone-line modem that requires the listed V.22bis 2,400 bps capability and compatibility with V.21, V.22, V.23, Bell 103, and Bell 212A formats. The integrated global DAA and capacitive isolation features are central to the line-interface role, while parallel phone detection supports systems that need to sense an off-hook condition. In a new design, the modem IC would be paired with the required telephone-network interface components and a host controller. It is best suited to legacy equipment refreshes rather than modern broadband or software-defined modem platforms.
Empfohlen
Industrial Remote-Control Terminal
The SI2400-KS can be considered for an industrial remote-control terminal that still communicates over an analog telephone line rather than an Ethernet or cellular network. Its 2.4 kbps V.22bis modem function and global DAA integration reduce the need for a separate line-interface block, while the listed overcurrent protection and isolation features support protection-oriented designs. The surrounding equipment must still meet the relevant line-network and isolation requirements. Since operating temperature, supply voltage, and exact timing are not present in the supplied evidence, the component should be released only after checking the original manufacturer documentation and the installed system's environmental limits.
Empfohlen
Legacy Remote Diagnostics
The SI2400-KS is suitable for legacy remote-diagnostic equipment that needs a low-speed modem channel for configuration, status reporting, or service access. The verified V.22bis 2,400 bps capability provides the required older modem class, while V.21, V.22, V.23, Bell 103, and Bell 212A support broadens compatibility with existing terminal equipment. A system designer can place the IC in the service path while preserving the established telephone-line DAA and controller interface. The design should account for country-specific line behavior, off-hook detection, surge exposure, and firmware support; those details are not fully specified by the supplied search records.
Empfohlen
V.25 Fast-Connect Control Link
The SI2400-KS is applicable when a legacy communications product depends on V.25 fast-connect behavior or the listed modem security and call-control protocols. The device's 2.4 kbps V.22bis modem core and integrated DAA make it useful for equipment that must maintain compatibility with established analog-line procedures rather than replace them with a modern packet modem. In a controller-based product, the IC would operate with the original host firmware, line-network interface, and phone-detection arrangement. Verify exact timing, protocol compatibility, and firmware dependencies in the manufacturer documentation before using the part in a newly designed system.
Empfohlen
Embedded Telephone Equipment
The SI2400-KS can be used as the modem interface element in embedded telephone equipment that still exposes an analog line port. Its 16-SOIC package supports conventional PCB assembly, while the integrated global DAA, capacitive isolation, parallel phone detection, and overcurrent protection provide the functional blocks associated with a system-side ISOmodem. This makes it more relevant to repair and redesign of mature equipment than to new high-throughput communications platforms. The engineer should verify the exact 16-pin land pattern, supply rails, line-side protection, isolation requirements, and operating temperature before committing the part to production.

Designhinweise
Do not treat the SI2400-KS as a modern broadband modem replacement. The verified device is a 2.4 kbps V.22bis ISOmodem intended for legacy analog telephone-line equipment. Preserve the original system-side interface, DAA implementation, and modem firmware, and confirm that the replacement application still supports V.21, V.22, V.23, Bell 103, and Bell 212A operation.
Use the official SI2400 datasheet land pattern and pin-1 orientation before laying out a 16-SOIC PCB. The retrieved data confirms a 16-SOIC package and tube packaging but does not provide a verified numbered pin table. Copying an unverified third-party pinout can reverse power, ground, DAA, isolation, or control connections and damage the equipment.
Estimated: verify the actual supply voltage, absolute maximum ratings, and power dissipation from the manufacturer datasheet before adding decoupling or selecting regulators. These values are [DATA_NEEDED] in the supplied data, so no capacitor value, current draw, or thermal estimate can be responsibly assigned. Follow the datasheet's recommended input, output, and reference bypassing arrangement exactly.
Keep analog telephone-line routing, DAA connections, isolation components, and digital modem-interface traces physically organized according to the original reference design. The listed capacitive-isolation feature does not eliminate the need for controlled creepage, surge protection, grounding, and country-specific line-interface compliance. Review the final layout with the line-network requirements and the manufacturer's application guidance.
Compliance-Informationen
The supplied search results identify lead-free status as an available specification field but do not provide its value. No RoHS, REACH, AEC-Q100, halogen-free, or conflict-minerals status was verified. AEC-Q100 is marked not_applicable because the product is a legacy communications interface IC and no automotive qualification was provided.
