MPN： SI3015-F-FS ✗ 停產SI3015-F-FS 概覽
An ISOModem chipset is a semiconductor implementation of International Telecommunication Union modem recommendations with an integrated line-side interface. In the broader product hierarchy, it belongs to the modem chipset, telecom interface IC, communication semiconductor, and interface IC categories. Its integrated direct access arrangement provides the physical interface between the modem data path and the external telephone network, reducing the amount of surrounding line-interface circuitry required by the host system.
The SI3015-F-FS supports 2400 bps modem operation and V.90 data formatting. The associated ISOModem description identifies V.22bis operation with error correction, while the distributor product classification identifies the component as a 2.4 kbps V.90 modem. These features make it relevant to legacy data communications, embedded telephone equipment, remote data access, and industrial modem applications where standardized 2400 bps line communication is required.
The device is packaged in a 16-pin SOIC measuring 3.90 mm wide. It is supplied in tube packaging and is identified as lead-free and RoHS-compliant. The SOIC-16 surface-mount format supports conventional PCB assembly while preserving a narrow outline for communication equipment with limited board area. The integrated line interface and standardized modem protocol reduce the functional blocks that the board designer must assemble around the chipset.
Typical implementations include telephone-line data terminals, embedded equipment-access modules, industrial remote-monitoring equipment, point-of-sale systems, and legacy telecommunications test equipment. In these systems, the SI3015-F-FS can serve as the line-side modem element while a host processor or communications controller manages the data protocol and higher-level application traffic.
Designers should verify the external line-network components, interface timing, isolation strategy, and system grounding against the manufacturer application information before production release. Because the SI3015-F-FS is a complete modem-oriented part rather than a general-purpose serial transceiver, firmware, host-driver, and country-specific telephone-network requirements remain important integration constraints.
This page organizes the SI3015-F-FS identification, package information, compliance details, drop-in comparison candidates, and application guidance into an engineering-focused reference. It also highlights which replacement claims can be supported by documented part identities and which electrical or pin-level details still require confirmation from the manufacturer datasheet.

典型應用
SI3015-F-FS 適用於 6 應用s: Telephone-Line Data Terminal, Industrial Remote-Monitoring Equipment, Embedded Equipment-Access Module, Point-of-Sale Communication System, Telecommunications Test Equipment, Legacy Remote-Service Adapter.
Telephone-Line Data Terminal
The SI3015-F-FS fits a telephone-line data terminal requiring a standardized 2400 bps modem connection rather than a general-purpose UART interface. Its V.22bis ISOModem operation, error-correction capability, and integrated direct access arrangement consolidate the modem and line-interface functions into a 16-SOIC footprint. The programmable line interface also helps the equipment adapt to different telephone-network requirements. The designer should use the manufacturer application circuit to select the external line-network components and validate network timing and isolation requirements.
推薦
Industrial Remote-Monitoring Equipment
Industrial monitoring equipment can use the SI3015-F-FS when a legacy telephone line is the available communications path. The 2400 bps modem rate is sufficient for command polling, status reporting, and low-volume configuration updates, while V.90 formatting and V.22bis operation provide a defined communications basis. Its integrated direct access arrangement reduces the external line-interface burden. Production equipment must still verify line quality, surge exposure, grounding, and operating-environment requirements for each deployment site.
推薦
Embedded Equipment-Access Module
The SI3015-F-FS is appropriate for an embedded access module that must establish a modem connection over a subscriber telephone line. The 16-SOIC package preserves board space, and the integrated direct access arrangement places the line-side interface close to the modem circuitry. V.22bis operation and error correction support the standardized modem session, while V.90 formatting supports compatible host equipment. The host processor remains responsible for application protocols, authentication, session management, and equipment supervision.
推薦
Point-of-Sale Communication System
A point-of-sale terminal requiring wired remote transactions can use the SI3015-F-FS where a 2400 bps telephone modem path is specified. The chipset consolidates modem operation and the direct access arrangement, avoiding a separate generic line-interface IC in the design. V.90 data formatting and V.22bis error-corrected operation support legacy terminals that already communicate through compatible modem protocols. Deployment testing should include line impairment, call-establishment timing, retry behavior, and regional telephone-network compatibility.
推薦
Telecommunications Test Equipment
The SI3015-F-FS can serve as the modem element in legacy telecommunications test equipment that generates or receives 2400 bps data sessions. Its V.22bis ISOModem functionality and integrated direct access arrangement allow test systems to exercise line-oriented modem behavior with fewer external blocks. The 16-SOIC package is suitable for compact instrumentation boards, while tube packaging supports manual or production handling. Calibration routines, test-loop arrangements, and injected line impairments should follow the manufacturer test guidance.
推薦
Legacy Remote-Service Adapter
The SI3015-F-FS is suitable for a remote-service adapter that uses an existing telephone network to carry maintenance commands and diagnostic data. Its 2400 bps operation offers a standardized low-speed fallback for installations without modern broadband connectivity. V.22bis error correction improves robustness over impaired lines, and the integrated direct access arrangement simplifies the physical interface. System planning should include call timing, line protection, watchdog recovery, and secure remote-access controls around the communications channel.

設計說明
Route the telephone-line and analog modem circuitry as a tightly controlled section of the PCB. Keep the line-side signal path short, place its network components close to the SI3015-F-FS, and maintain the clearances and isolation approach specified by the manufacturer application circuit. Separate this area from switching supplies and high-current return paths to reduce differential noise coupling into the 2400 bps modem path.
Use the manufacturer power-decoupling configuration and verify supply sequencing against the SI3015-F-FS electrical limits. Place the required bypass capacitors directly at the relevant supply pins with short ground returns, and avoid routing sensitive analog returns beneath noisy digital or power-converter sections. Because supply-voltage and current limits are not identified in the product summary, obtain them from the manufacturer datasheet before selecting the regulator.
Do not treat a shared SI3015 family name as proof of an unconditional drop-in replacement. Compare all 16 SOIC pin assignments, operating voltage, current consumption, timing, temperature grade, and protocol options for the exact production suffix. The SI3015-FSR record was excluded because the ordering-suffix difference requires documentation and a reel-format variation alone does not establish engineering interchangeability.
Preserve the manufacturer-recommended relationship between the modem circuitry, external telephone-network components, and grounding structure. Avoid long parallel runs between the line-side path and noisy system signals, and keep protection-device current away from sensitive analog ground paths. Validate the assembled board against modem error performance and call-establishment reliability across the intended line conditions.
