SI2415-C-FS - 14.4kbps ISOmodem System-Side IC | Skyworks
料号： SI2415-C-FS ✓ 量产中SI2415-C-FS 概述
An ISOmodem is a dedicated data-communications interface that integrates modem-related signal processing into a dedicated IC rather than implementing the protocol entirely in general-purpose digital logic. Within the equipment hierarchy, this part belongs to the modem interface class, within communication interface ICs, within integrated circuits. Supporting multiple data formats lets one physical design accommodate legacy and higher-rate V-series or Bell-mode connections.
The principal features of the SI2415-C-FS include 14.4 kbps operation, support for V.21, V.22, V.23, V.29, V.32, Bell 103 and Bell 212A formats, and a 16-SOIC package measuring 0.154 inches, or 3.90 mm, in width. Its lead-free construction and RoHS-compliant status are suitable for modern production environments. Commercial temperature-grade sourcing information and terminal-form details are associated with the device in distributor records.
Skyworks positions the SI2415 as part of the ISOmodem family, which spans modem speeds from 2,400 bps to 56,000 bps and combines line-side and system-side functions into a chipset-oriented implementation. The SI2415-C-FS is identified specifically as the system-side device in the 16-pin package, making it suitable for designers building compact data links into terminal, communications or embedded equipment.
Typical uses include legacy data-terminal equipment, point-of-sale systems, industrial data collection, telecommunications interface assemblies and embedded control products that require Bell 103, Bell 212A or V-series modem compatibility. A complete modem implementation may pair the system-side IC with a corresponding line-side device, an isolation barrier, telephone-network coupling components and an external data interface controller.
When laying out a design, treat the telephone-line interface as a high-voltage, high-transient environment and follow the manufacturer’s isolation and protection guidance. Keep sensitive analog and line-side circuitry away from digital switching nodes, and use the datasheet pin-description table when assigning every 16-pin SOIC connection. Confirm line-side component values, crystal or timing requirements and interface levels against the complete chipset documentation before release.
This page consolidates the device’s data formats, package characteristics and compliance attributes with practical implementation guidance. It also identifies the same-family SI2415-C-FT sourcing option for design teams evaluating package-compatible supply alternatives before committing a production BOM.

典型应用
SI2415-C-FS 适用于 6 应用s: Legacy Point-of-Sale Terminal Interfaces, Data-Terminal Equipment Interfaces, Industrial Data Collection Equipment, Telecommunications Network Interfaces, Embedded Control and Remote-Management Links, Legacy Communication Test Equipment.
Legacy Point-of-Sale Terminal Interfaces
The SI2415-C-FS fits point-of-sale terminals that communicate over legacy telephone-style data networks using Bell 103 or Bell 212A formats. Its support for V.21, V.22, V.23, V.29 and V.32 formats permits one interface design to address several legacy protocols, while the 16-SOIC package limits board area in space-constrained terminal electronics. The device handles the system-side modem function; a compatible line-side circuit, protection network and isolation arrangement are still required. Designers should verify the required data format, host interface level and network timing against the manufacturer application information.
推荐
Data-Terminal Equipment Interfaces
The SI2415-C-FS can provide the system-side modem interface in data-terminal equipment that must interoperate with Bell and V-series data devices. Supporting seven documented formats at rates up to 14.4 kbps allows a single product family to address legacy asynchronous modem connections without relying on a general-purpose processor to implement modulation-related functions. The 16-SOIC package is useful where connector area is constrained, although the complete design must still include line-side signal conditioning, transient protection and the required isolation. Verify framing, timing and electrical levels before releasing the PCB.
推荐
Industrial Data Collection Equipment
Industrial collectors that communicate with older remote instruments or controllers can use the SI2415-C-FS when their protocol requires V.21, V.22, V.23, V.29, V.32, Bell 103 or Bell 212A. The dedicated system-side modem interface reduces the modem-function load carried by the embedded controller. Its 14.4 kbps ceiling is appropriate for supervisory and configuration links rather than bulk file transfer. Because such equipment may sit near an unprotected telephone pair, use the manufacturer’s line-side protection and isolation guidance and validate the design under the applicable transient conditions.
推荐
Telecommunications Network Interfaces
The SI2415-C-FS is suited to compact network-interface assemblies that terminate legacy modem data formats on the system side. Its support for both Bell 103 and Bell 212A alongside five V-series formats allows equipment to cover multiple installed-base connection types. The device is only one element of the modem path: designers must add the appropriate line-side chipset element, coupling components and protection network. The 16-SOIC package also helps limit board space, while system partitioning determines whether additional isolation is needed for the target interface.
推荐
Embedded Control and Remote-Management Links
Embedded controllers can use the SI2415-C-FS for remote-management or configuration links when the remote endpoint uses a legacy modem protocol. At up to 14.4 kbps, the link is appropriate for command traffic, status exchange and short configuration records rather than continuous bulk transfers. Supporting V.21 through V.32 and Bell 103 or Bell 212A provides protocol flexibility across mixed equipment fleets. Keep firmware aware that the modem protocol, carrier timing and error handling operate below the application transport layer, and confirm the host-side electrical interface in the manufacturer documentation.
推荐
Legacy Communication Test Equipment
Test and service equipment that needs to interface with Bell- or V-series modem endpoints can benefit from the SI2415-C-FS system-side interface. Supporting seven data formats allows a single tester platform to address legacy equipment commonly found in telecommunications networks, industrial installations and older data terminals. The part’s 14.4 kbps rate is adequate for control and diagnostic traffic. Test-equipment designers should still implement the corresponding line-side interface, calibrate the transmit and receive paths, and verify isolation requirements before connecting the assembly to external lines.

设计说明
Separate the telephone-line and line-side signal path from digital interface routing on the PCB. Keep the line-side section away from clocked circuitry and use the shortest practical connections for sensitive modem signals. Follow the manufacturer’s reference layout for component placement and grounding; do not derive the analog and digital partitioning from a generic RS-232 layout because the external interface includes telephone-network transients and isolation requirements.
The SI2415-C-FS is the system-side member of the chipset, so it cannot by itself implement a complete telephone-line modem connection. Specify the corresponding line-side device, coupling network, protection components and isolation method in the schematic. Also confirm that the selected ordering suffix has the required shipping form; tube packaging and tape-and-reel packaging are not interchangeable in the same production flow.
Treat the line-side network as an externally accessible interface even when the modem is installed inside an enclosure. Apply the manufacturer’s transient-protection and isolation recommendations at the connector or line-entry point, and validate the assembled board against the applicable product safety tests. Avoid long unprotected traces between the connector and protection network, because their inductive length can reduce the effectiveness of clamping devices.
Use the manufacturer’s 16-SOIC land pattern and pin-1 marking during PCB layout, and check the exact footprint against the terminal dimensions in the package drawing. Provide adequate decoupling at the device supply pins, route return currents continuously and keep the modem signal area free of high-current switching paths. Prototype the line-side section early because network-interface timing and protection margins are more difficult to change than host-interface logic.
