MPN: SI2415-D-GT ✓ فعالSI2415-D-GT نمای کلی
An integrated modem IC is a mixed-signal semiconductor that combines a data analog channel, modulation and demodulation circuitry, protocol handling, and a host-facing interface. For the SI2415-D-GT, this integration places legacy ITU-T and Bell modem support into a compact surface-mount package. The resulting device can reduce the component count and board area required by a discrete telephone-interface implementation while centralizing modem-specific functions.
The SI2415-D-GT supports V.21, V.22, V.23, V.29, and V.32 formats, along with Bell 103 and Bell 212A operation. The associated family documentation also identifies Bell 300 bps operation, V.44, V.42, V.42bis, MNP2-5, automatic rate negotiation, Fast Connect, and Type I and Type II caller-ID decoding as supported capabilities. These functions target analog telephone equipment, fax systems, remote-access products, and other legacy WAN equipment.
The SI2415 family combines data processing with telephone-network interface functions, including a global DAA-oriented implementation. Its operating supply is identified as 3 V in comparison records, while the verified distributor listing identifies the device as a network controller and processor IC. Industrial temperature grade, surface mounting, a 24-pin TSSOP package, and a 4.40 mm package width are also identified for this device family.
Typical applications include caller-ID terminals, fax machines, modem cards, telephone answering equipment, remote diagnostics, and embedded legacy-telephony controllers. The IC is particularly relevant to equipment that must retain Bell 103 or Bell 212A interoperability while also supporting higher V-series modem standards for data transfer and fax transmission.
A successful design must follow the manufacturer’s recommended external-network, power, interface, and decoupling arrangements. The 24-pin TSSOP footprint requires careful PCB routing, especially around telephone-line and host-interface signals. Because legacy modem ICs combine sensitive analog functions with digital control, stable supply voltage, grounding, and component placement are essential for predictable communication performance.
This product page combines package and protocol information, practical application guidance, drop-in-family comparisons, and design notes to support component selection, PCB planning, and sourcing. For exact electrical limits, pin assignments, interface timing, and approved external circuitry, use the manufacturer’s SI2415-family datasheet and its associated reference designs.

کاربردهای معمول
SI2415-D-GT مناسب است برای 6 کاربردs: Legacy Fax Modem Interfaces, Caller-ID Terminals, Remote Diagnostics Systems, Telephone Answering Equipment, Modem Cards and Network Controllers, Industrial Telephone Data Gateways.
Legacy Fax Modem Interfaces
The SI2415-D-GT fits legacy fax equipment that must connect with endpoints supporting V.21, V.22, V.23, V.29, or V.32. Its 2.4k modem designation identifies the target class, while V.42, V.42bis, MNP2-5, automatic rate negotiation, and Fast Connect provide modem error handling and faster connection capabilities for compatible systems. Installing the function in a 24-pin TSSOP reduces board area compared with a discrete implementation. Designers should follow the manufacturer’s telephone-network and host-interface circuits, validate country-specific line-interface requirements, and test real-world negotiation behavior with the intended fax equipment.

Caller-ID Terminals
The SI2415-D-GT is appropriate for caller-ID terminals that require both legacy Bell compatibility and data-modem operation. The SI2415 family supports Type I and Type II caller-ID decoding, while Bell 103 and Bell 212A maintain compatibility with older telephone-network equipment. The 24-pin TSSOP package permits a compact controller board, and the documented 3 V operating supply simplifies low-voltage system integration. The telephone-line side remains the critical design area, so use the manufacturer’s recommended isolation, protection, and network components. Validate detection timing and line-state behavior across the regional signaling systems that the finished product must support.

Remote Diagnostics Systems
The SI2415-D-GT can form the communications core of a remote diagnostics or service-access system built around analog telephone lines. V.22, V.23, V.29, and V.32 support data transfer at the device’s 2.4k modem class, while automatic rate negotiation helps the two endpoints select a compatible operating mode. Fast Connect can shorten connection setup when both endpoints implement the required procedure. The 24-pin TSSOP keeps the modem function compact, but the surrounding interface must preserve the signal integrity expected by the telephone-line front end. Test line noise, echo, ring voltage, and connection timing in the deployed network rather than relying only on laboratory loopback tests.

Telephone Answering Equipment
The SI2415-D-GT can support legacy answering equipment that needs remote data access in addition to voice-line functions. Bell 103 and Bell 212A provide compatibility with older endpoints, while the V-series modes support more capable connections. Type I and Type II caller-ID decoding can assist products that display or process calling-party information. Its 24-pin TSSOP package is practical for compact control boards, and its 3 V operating supply aligns with modern embedded control hardware. The critical implementation task is separating sensitive telephone-line signals from the host interface and control circuitry. Follow the manufacturer’s grounding, decoupling, and isolation guidance, and verify acoustic, hook-switch, and modem interoperability during system validation.

Modem Cards and Network Controllers
The SI2415-D-GT fits add-on modem cards and embedded network-controller products designed around legacy WAN access. Its support for Bell 103, Bell 212A, and five principal V-series formats allows one controller design to address several installed-base connection methods. The integrated modem function limits the external circuitry compared with a discrete codec and modulation solution, while the 24-pin TSSOP supports compact board layouts. Product designers should still allocate careful routing and grounding for the line interface and use stable, low-noise supply distribution. Firmware must configure the operating mode consistently with the selected standards, and validation should include negotiation against both Bell and ITU-T endpoints to confirm full intended compatibility.
پیشنهادی
Industrial Telephone Data Gateways
The SI2415-D-GT is useful in industrial gateways that bridge legacy telephone equipment into a modern control network. Its 24-pin TSSOP package and 3 V operating supply support compact embedded hardware, while V.21 through V.32 and Bell 103 or Bell 212A cover common analog-data access methods. The industrial temperature grade makes the device a candidate for controlled industrial environments, subject to confirmation of the full operating-temperature limits. Designers should implement the manufacturer’s recommended network protection and isolation, particularly when the gateway connects to external lines. Firmware should expose explicit mode controls, and production testing should exercise line impairment, retry behavior, and caller-ID handling to verify dependable field operation.

یادداشت‌های طراحی
Keep the telephone-line interface section physically separated from the host interface and control circuitry. Route sensitive modem signals over continuous ground references, minimize loop area, and place the manufacturer-recommended external components close to their associated pins. Because the SI2415 family combines analog telephone functions with digital processing, inconsistent return paths can increase noise sensitivity even when the modem standards and supply voltage are correct.
Provide a stable 3 V supply with low impedance at the IC and use the decoupling arrangement shown in the SI2415 family datasheet. Place bulk and local bypass capacitors close to their power pins, maintain short ground connections, and avoid routing switching-regulator return current through the modem analog area. Verify the minimum on-time and maximum ripple for every operating mode because the documented 3 V supply does not by itself establish adequate transient margin.
Do not substitute an ordering suffix solely because the lead count and body size match. SI2415-D-GT, SI2415-D-FT, and SI2415-D-FTR belong to the same core family but differ in orderable packaging, while SI2415-C-GT differs in revision. Confirm the manufacturer ordering table, reel or tube requirement, device labeling, and pin assignments before releasing a purchase order or approving a substitution.
Validate modem behavior with realistic telephone-line impairments rather than only a local loopback. Test line noise, attenuation, echo, off-hook timing, caller-ID signaling, and negotiation with both Bell and ITU-T endpoints. The SI2415-D-GT supports several legacy formats, but successful system operation also depends on the external network interface, country-specific line circuitry, firmware configuration, and endpoint behavior.
