SI3010-FS - 2.4 kbps Global DAA | Silicon Labs
料号： SI3010-FS ✓ 量产中SI3010-FS 概述
A direct access arrangement, or DAA, is the line-side interface between a modem data terminal and a public switched telephone network. It converts analog line conditions into signals that can be processed by modem circuitry while providing the required isolation, hook-state detection, dialing, and line-current handling. A global DAA is designed to support internationally configurable telephone-line behavior rather than a single country-specific line interface.
The SI3010-FS provides a 2.4 kbps data rate and operates from 3 V to 3.6 V, making it suitable for legacy V.22bis-class data communication equipment. Its 16-pin SOIC package is a surface-mount format suitable for automated assembly, and the reel configuration supports production feeding. The documented operating range of 0°C to 70°C identifies the SI3010-FS as a commercial-temperature device.
The integrated DAA reduces the number of external line-interface functions required in a complete modem design. This can simplify the printed-circuit-board layout while preserving a standardized telephone-line interface. Because the part belongs to the Si2401 and Si2404 ISOmodem families, it is particularly relevant to designs requiring a line-side DAA paired with established modem controller or codec functionality.
Typical uses include 2400 bps modem hardware, fax and data terminal equipment, industrial data links operating through telephone networks, and legacy communications controllers that require a globally programmable DAA. The SI3010-FS is also useful when a completed modem design must be maintained with an established 16-pin SOIC footprint and 2.4 kbps class performance.
Designers should verify the complete SI3010 or Si240x companion-device arrangement because the DAA also requires suitable line-interface components and an appropriate host or modem companion. PCB layout must preserve the manufacturer's recommended analog and digital partitioning, while component selection must account for the telephone network's voltage and current requirements.

典型应用
SI3010-FS 适用于 6 应用s: 2400 bps Telephone Modem, Industrial Data Communication, Legacy Fax Equipment, Telephone-Line Data Terminal, Telecom Interface Test Equipment, Embedded Modem Gateway.
2400 bps Telephone Modem
The SI3010-FS fits a 2400 bps telephone modem because it provides the integrated global direct access arrangement identified with the V.22bis ISOMODEM family. Its 2.4 kbps data rate and 3 V to 3.6 V operating range align with legacy modem hardware using a 3.3 V supply. Placed beside the companion modem electronics in a 16-pin SOIC footprint, the device provides the line-side interface while the external circuit handles required telephone-network coupling and protection. The principal design consideration is validating the exact line components, country configuration, and companion-device arrangement against the applicable SI3010 documentation.
推荐
Industrial Data Communication
The SI3010-FS can support industrial data-communication equipment that uses the public telephone network as its transmission medium. The integrated global DAA provides the line-side signaling interface, while the 2.4 kbps V.22bis-class data function is appropriate for legacy supervisory, remote, or terminal links. Its 0°C to 70°C specification suits controlled industrial enclosures but not outdoor equipment without additional thermal design. Because telephone-line interfaces must withstand network transients and maintain isolation, the SI3010-FS should be paired with the manufacturer-specified protection and line-network components rather than used as an unrestricted transceiver.
推荐
Legacy Fax Equipment
The SI3010-FS is applicable to legacy fax and terminal equipment built around 2400 bps modem operation. The V.22bis ISOMODEM association provides a defined functional context, while the global DAA supports configurable telephone-line behavior across different networks. In such equipment, the DAA occupies a compact 16-pin SOIC footprint and operates from the same nominal 3.3 V class of supply used by companion modem logic. Maintenance teams should preserve the original analog network design, verify component substitutions against the country-specific line requirements, and avoid assuming that every later SI3010 suffix is approved for an existing qualified fax platform.
推荐
Telephone-Line Data Terminal
The SI3010-FS is suitable for a telephone-line data terminal requiring a compact global line interface. Its 2.4 kbps rate provides compatibility with older V.22bis-class systems, while the integrated DAA reduces the amount of line-interface functionality that must be implemented elsewhere on the board. The 16-pin SOIC package supports automated surface-mount assembly and the reel format identified in the packaging data. Designers should provide adequate isolation and surge protection, implement the specified external telephone-network network, and validate operation across every ringing voltage, line current, and impedance condition required by the deployment market.
推荐
Telecom Interface Test Equipment
The SI3010-FS can be used in telecom interface test and maintenance equipment designed around legacy telephone-line signaling. The integrated global DAA gives the equipment a defined interface toward the line side, and the 2.4 kbps V.22bis-class function allows controlled modem-tone and data-path testing. The 3 V to 3.6 V supply requirement supports integration into 3.3 V test instruments, while the 16-pin SOIC package leaves board area for instrumentation and signal-conditioning circuitry. A safe test design must include the prescribed isolation boundary, protection network, and controlled line interface; the DAA IC alone must not be connected directly to an unprotected analog telephone line.
推荐
Embedded Modem Gateway
The SI3010-FS can form part of an embedded modem gateway for equipment that requires remote connectivity over a telephone line. The SI3010 family provides the globally configurable DAA needed at the network boundary, while the companion modem circuitry handles digital data processing. Its 2.4 kbps throughput is modest but adequate for supervisory channels, configuration transfer, and low-bandwidth management tasks. The 16-pin SOIC package simplifies compact surface-mount layouts, yet the external line interface remains the dominant risk area. System integrators should preserve the recommended isolation components and validate the complete gateway against the relevant telephone-network requirements before field deployment.

设计说明
Preserve the separation between the telephone-line analog section and the digital modem section. Place the SI3010-FS, its decoupling components, and the associated line-network components according to the manufacturer reference design. Avoid routing high-current hook-switch or surge paths beneath the DAA and keep sensitive nodes short. The supplied data does not include a verified pin map or recommended layout drawing, so engineers should use the exact device revision's documentation rather than infer connections from package position.
Use a regulated source within the verified 3 V to 3.6 V operating range and provide local high-frequency decoupling close to the device. Check absolute maximum limits and sequencing requirements in the manufacturer datasheet for the exact SI3010-FS revision. Telephone-interface protection components and hook-switch circuitry can create transients, so the power system must remain stable when the line network changes state. The SI3010-FS itself is not characterized here as a high-dissipation component.
Do not treat a shared SI3010 family name or package as sufficient evidence of production interchangeability. Confirm the exact suffix, silicon revision, top marking, datasheet revision, external component list, and firmware expectations when substituting SI3010-F-FSR, SI3010-F-FS, or SI3010-F-GS. Telephone products also require verification of isolation, surge immunity, network approval, and country-specific line behavior. A replacement that is pin-compatible can still require schematic or firmware review.
The verified operating-temperature specification is 0°C to 70°C, so place the assembled board in an enclosure that limits worst-case internal temperature. Estimate system heat from the complete modem board rather than from the DAA IC alone because external line-interface and power components may dissipate more energy. No verified thermal resistance or power-dissipation figure was supplied for the SI3010-FS; do not use an assumed junction-temperature calculation without the manufacturer data.
