SI3018-GS 개요

Silicon Labs SI3018-GS is a telecom Direct Access Arrangement interface integrated circuit supplied in a 16-pin SOIC package. The verified product information identifies it as the SI2493 ISOmodem line-side device, with 16 terminations and a lead-free data sheet. It is intended for telephone-line interface and telecom equipment designs requiring a dedicated line-side DAA solution. The SI3018-GS belongs to the broader Direct Access Arrangement -> telephone-line interface -> telecom interface IC -> semiconductor hierarchy.

A Direct Access Arrangement interface IC is the line-facing member of a subscriber-line or modem interface. It connects a communications system to an analog telephone line while supporting the signaling, isolation, and termination functions required by that line. The verified information identifies SI3018-GS as a 16-SOIC telecom interface and specifically associates it with the SI2493 ISOmodem line-side device, making it appropriate for legacy and established telephone-interface platforms rather than unrelated general-purpose interface products.

The SI3018-GS provides 16 terminations and uses a 16-SOIC package. The verified sourcing results specifically describe it as a lead-free telecom interface IC and classify it as a Direct Access Arrangement device. These package and termination details are the principal verified features for comparing it with other line-side interface components. Its principal advantage is integration into a dedicated telecom interface role rather than requiring a collection of unrelated line-interface functions.

Functionally, the SI3018-GS is associated with the SI2493 ISOmodem line-side architecture. The available manufacturer-family material identifies the SI3056 family as providing four AC termination impedances for SI3018 line-side devices and sixteen AC termination impedances for SI3019 line-side devices. This context establishes SI3018 as the lower-termination-count member of the referenced line-side family, while detailed operating conditions remain available through the linked Silicon Labs family document.

Typical applications include analog telephone-line interfaces, customer-premises equipment, modem line-side designs, and telecom interface cards. In each case, the device is positioned on the line side of the communications architecture rather than directly beside a general-purpose digital processor. System designers must still verify line impedance, isolation, protection, ringing, and regulatory requirements against the applicable Silicon Labs documentation before releasing a production design.

The principal design consideration is to use the exact SI3018-GS data sheet and pin configuration during schematic capture and PCB layout. Because the verified material confirms the 16-SOIC package but does not expose a complete numbered pin table, engineers should not infer pin assignments from generic DAA devices or from the SI3018-F-GS listing. Component sourcing and inventory status should also be checked before committing to a high-volume build.

This product page combines the verified package classification, telecom-interface role, termination count, family relationships, distributor sources, and available drop-in references with practical selection guidance. It also distinguishes verified SI3018-GS information from unverified parameters that require confirmation from the manufacturer data sheet before design-in.

일반적인 애플리케이션

SI3018-GS 적합 용도: 6 애플리케이션s: Analog Telephone-Line Interface, Customer Premises Equipment, Modem Line-Side Card, Legacy Voice Gateway, Telecom Interface Test Equipment, Industrial Telephone Control Panel.

🌐

Analog Telephone-Line Interface

The Silicon Labs SI3018-GS fits an analog telephone-line interface because it is identified as a Direct Access Arrangement interface IC associated with the SI2493 ISOmodem line-side device. Its 16-pin SOIC package fits established line-card and subscriber-interface layouts, while the verified 16-termination listing provides a useful starting point for network-component selection. The engineer should confirm the exact impedance configuration, ringing behavior, isolation requirements, and country-specific line interface against the SI3018-GS data sheet before production.

🏭

Customer Premises Equipment

The SI3018-GS is applicable to customer-premises equipment that terminates an analog telephone line and connects it to modem or voice-processing circuitry. Its dedicated telecom DAA role is more appropriate than using a general-purpose interface IC for this task. The verified 16-SOIC package supports compact board integration, but the product's suitability depends on line impedance, surge exposure, isolation, and regulatory requirements. Those requirements must be validated with the exact manufacturer documentation and local network rules.

🌐

Modem Line-Side Card

SI3018-GS is explicitly associated with the SI2493 ISOmodem line-side device, making it a logical candidate for a modem line-side card or legacy data-access platform. The verified 16-pin SOIC construction allows reuse of an existing footprint when the exact pin assignments are confirmed. The related family material identifies four AC termination impedances for the SI3018 line-side device, but engineers should not assume the meaning of the 16-termination listing without checking the exact data sheet and termination table.

🎧

Legacy Voice Gateway

A legacy voice gateway can use the SI3018-GS where an established analog line interface is required rather than a purely digital audio interface. The device's DAA classification provides a direct path from telephone-line circuitry into the surrounding modem or voice system. The verified package is 16-SOIC, but the supplied information does not establish ringing voltage, codec integration, line-feed control, or thermal limits. Those details must be checked before adapting the part to a new gateway design.

🔧

Telecom Interface Test Equipment

SI3018-GS may be used in telecom interface test equipment that reproduces a line-side DAA function around a channel simulator, analyzer, or protocol test platform. The dedicated interface role helps separate analog line conditioning from the measurement or processing circuitry. Its 16-SOIC package is convenient for reusable hardware, while the manufacturer-family reference supplies useful context for the number of AC termination impedances. Exact test limits and supported line parameters remain to be established from the SI3018-GS data sheet.

🏭

Industrial Telephone Control Panel

The SI3018-GS can serve in an industrial telephone control panel when the system must communicate over an analog subscriber line. Integrating a dedicated DAA interface reduces the amount of line-facing circuitry that must be handled elsewhere in the controller. Nevertheless, industrial exposure adds requirements for surge protection, isolation, temperature range, and long-term reliability that were not quantified in the verified data. Those conditions must be verified before using the device outside a controlled telecom environment.

What is SI3018-GS?
SI3018-GS is a Silicon Labs 16-pin SOIC Direct Access Arrangement telecom interface IC associated with the SI2493 ISOmodem line-side device. According to the verified DigiKey listing, it is a telecom IC DAA in a 16-SOIC package; the available Mouser result additionally identifies it as a lead-free telecom interface component. It is intended for designs that connect equipment to an analog telephone line.
What package does SI3018-GS use?
SI3018-GS uses a 16-pin SOIC package. This package is confirmed by the verified DigiKey result, which describes the component as a 16-SOIC telecom Direct Access Arrangement, and by the Ampheo listing, which identifies a 16-SOIC package. The exposed-pad count and exact mechanical dimensions were not supplied in the verified data and must be checked against the manufacturer data sheet.
Where can I download the SI3018-GS datasheet PDF?
The SI3018-GS documentation should be obtained from Silicon Labs or the linked Silicon Labs family document for the SI3018, SI3019, SI3010, and SI3056 devices. The verified source set includes https://www.skyworksinc.com/-/media/Skyworks/SL/documents/public/data-sheets/si3056.pdf, which provides family-level information. Distributor listings also expose datasheet access for SI3018-GS, but an exact document number was not provided and therefore is not asserted.
Where can I find the SI3018-GS pinout?
The SI3018-GS pinout must be obtained from the manufacturer data sheet rather than inferred from a distributor category page. The verified sources confirm that the device is a 16-SOIC telecom DAA, but they do not provide a complete numbered pin table. Consequently, this page records the pinout as null and recommends checking all 16 pins, including power and no-connect positions, against the exact SI3018-GS revision before layout.
What is the difference between SI3018-GS and SI3018-F-GS?
SI3018-GS and SI3018-F-GS are closely related Silicon Labs SI3018 line-side DAA listings, and the verified search results show both in 16-SOIC telecom-interface families. However, the supplied data does not state which electrical or ordering parameters distinguish the G suffix from the F suffix. Engineers should therefore treat SI3018-F-GS as a family-related candidate, not an automatic replacement, until the exact data sheets confirm identical pins, termination values, ratings, and qualification status.
Is SI3018-F-GSR a drop-in replacement for SI3018-GS?
SI3018-F-GSR is a Skyworks Solutions 16-SOIC telecom DAA candidate for SI3018-GS, and the verified DigiKey result confirms its 16-SOIC package and DAA classification. Nevertheless, the supplied cross-reference evidence does not provide a pin-by-pin comparison or complete electrical ratings, so it cannot be certified as a drop-in replacement without manufacturer-level validation. Confirm pinout, impedance configuration, isolation, ringing, and environmental ratings before substitution.
What is the best drop-in replacement for SI3018-GS?
No alternative can be confirmed as a fully verified drop-in replacement from the supplied data. The closest documented candidates are the Silicon Labs SI3018-F-GS and the Skyworks Solutions SI3018-F-GSR, both associated with the 16-SOIC telecom DAA category. Because the exact numbered pinout and full electrical tables were not supplied, procurement should treat them as conditional drop-in candidates pending comparison with the exact SI3018-GS manufacturer data sheet.
Can SI3018-GS be used in a telephone-line interface circuit?
Yes, SI3018-GS is specifically positioned for telephone-line and modem line-side interface circuits. The verified product descriptions classify it as a Direct Access Arrangement interface IC and associate it with the SI2493 ISOmodem line-side device. Its suitability still depends on the required line impedance, termination network, isolation, surge protection, ringing behavior, and country-specific network requirements, which must be checked against the manufacturer documentation.
SI3018-GS vs SI3018-F-GS: which is better for a legacy modem design?
SI3018-GS is the preferred choice when the existing legacy modem design was qualified specifically around the G suffix, because changing device variants can alter ordering codes, qualification, or undocumented electrical details. SI3018-F-GS is a reasonable family candidate only after its complete data sheet has been checked against SI3018-GS. The verified sources establish both as related SI3018-family telecom DAA devices but do not provide enough detail for a blanket interchangeability claim.
SI3018-GS vs SI3018-F-GSR: which DAA should a designer choose?
Choose SI3018-GS when preserving the original Silicon Labs SI3018-GS qualification and documentation is more important than exploring a second-source source. Consider SI3018-F-GSR only after confirming that its complete 16-pin pinout, termination values, electrical limits, isolation rating, and environmental qualifications match the target design. The verified cross-reference result confirms a 16-SOIC DAA package for SI3018-F-GSR, but it does not prove functional interchangeability.
When should I choose SI3018-GS instead of a discrete telephone interface?
Choose SI3018-GS when the design requires a proven integrated DAA function and the surrounding telephone-line interface has already been qualified around this device. A discrete approach can offer component-level flexibility but requires the integrator to reproduce the complete line termination, isolation, protection, and control behavior. The SI3018-GS approach is preferable when reducing interface complexity and relying on the manufacturer's telecom IC documentation are the main design priorities.
Is SI3018-GS suitable for modem line-side equipment?
Yes, SI3018-GS is suitable for modem line-side equipment because the verified listings explicitly associate it with the SI2493 ISOmodem line-side device. Its 16-SOIC construction and 16-termination interface identify it as a dedicated telecom DAA rather than a generic logic IC. Before schematic release, verify the exact supported line impedances and required external network against the SI3018-GS data sheet for the target country and carrier network.
How many terminations does SI3018-GS provide?
SI3018-GS provides 16 terminations, according to the verified Hotenda product result. Related manufacturer-family material states that the SI3018 line-side device uses four AC termination impedances, whereas the SI3019 line-side device uses sixteen; therefore, the listing's term '16 terminations' should not be interpreted as sixteen independently configurable AC impedances without checking the exact data sheet.
Where to buy SI3018-GS online?
SI3018-GS can be located through Silicon Labs and multiple distributor aggregators, including DigiKey, Mouser, Octopart, Hotenda, Xecor, and ICMASS. The verified results confirm product-page availability but do not expose current target-part unit prices. Octopart indicates comparisons across four distributors. Because inventory and pricing are dynamic, request a quotation or verify the authorized-distributor listing immediately before purchase; prices as of 2026-10-29 are not available in the supplied target-part data.
What is the price and lead time for SI3018-GS?
The current target-part price and lead time for SI3018-GS are not included in the verified data. The $2.5422 LCSC snippet applies to the related SI3018-F-GS listing and must not be treated as SI3018-GS pricing. Prices for SI3018-GS should therefore be checked as of 2026-10-29 directly with authorized distributors, while production planning should request a dated stock and lead-time commitment rather than relying on aggregator availability messages.
What are the key specifications of SI3018-GS that engineers should know?
The verified SI3018-GS specifications are its 16-pin SOIC package, Direct Access Arrangement function, association with the SI2493 ISOmodem line-side device, 16 listed terminations, and lead-free status. The supplied family document also places SI3018 in a four-AC-impedance line-side grouping. Input voltage, temperature range, isolation rating, impedance values, and full electrical limits were not included, so they remain subject to manufacturer-document confirmation before schematic or PCB release.

선택 가이드

Choose SI3018-GS when the design was qualified around the exact Silicon Labs G-suffix part and preserving the documented association with the SI2493 ISOmodem line-side device is important. SI3018-F-GS is the closest same-manufacturer candidate because it belongs to the SI3018 family and is offered in the same 16-SOIC format, but the F-versus-G differences must be checked before treating it as interchangeable. Consider SI3018-F-GSR when a second-source 16-SOIC telecom DAA is needed, provided its pinout, termination values, isolation, electrical limits, and qualification are verified. For new designs, do not select on package and function alone: confirm supported line impedances, ringing and line-feed behavior, surge requirements, operating temperature, and regional telecom compliance. If the objective is simply the lowest price, the $2.5422 SI3018-F-GS listing is a useful market reference but is not valid SI3018-GS pricing.

설계 노트

Do not substitute SI3018-GS based only on its SOIC-16 package and DAA classification. The verified material does not expose the exact numbered pin table or explain every suffix difference. Before replacing any installed part, compare power pins, ground connections, termination-control pins, isolation provisions, and no-connect positions against the manufacturer documents for both MPNs. A mechanically similar package can still require component changes or board-level rework.

Treat the analog line-side section as a high-impedance, high-surge environment. Place the SI3018-GS, its required termination components, protection devices, and isolation network according to the exact manufacturer reference layout. Keep switching-regulator loops, digital clocks, and high-current return paths away from line-side nodes. Do not infer trace spacing or grounding topology from the distributor snippets; use the applicable national and carrier line-interface requirements for final creepage, clearance, and surge design.

The supplied data does not specify input voltage, current consumption, quiescent current, or power dissipation, so rail sizing cannot be completed from this page. Verify the electrical maximum ratings and recommended operating conditions in the exact SI3018-GS data sheet. Confirm that every supply rail has adequate startup margin, decoupled routing, and fault behavior for the intended telecom application. If a replacement candidate is evaluated, compare its supply and power-consumption limits before considering pin compatibility.

Do not use the LCSC price of $2.5422 for SI3018-F-GS as the price of SI3018-GS; the verified snippet explicitly names a different MPN. The supplied SI3018-GS results confirm sourcing channels but omit target-part prices and dated stock. Request an authorized-distributor quotation as of the purchasing date, and confirm lead time, traceability, date code, and lifecycle status before allocating the component to a production schedule.
