SI3010-GS - 3.6V DAA Interface IC | Silicon Labs | Telecom
MPN： SI3010-GS ✗ 停產SI3010-GS 概覽
A Direct Access Arrangement is a subscriber-line interface controller that separates a telephone line codec from the host digital signal processor or CPU. In this product hierarchy, the SI3010-GS is a DAA interface IC within the broader category of telecom interface ICs. Such devices traditionally handled line-state signaling, loop control, and the host-side data interface used by customer-premises equipment, telephone adapters, and other legacy voice systems.
The SI3010-GS offers a 3 V to 3.6 V operating supply, 15 mA supply current, and parallel, SPI, and UART host-interface options. Its 16-pin SOIC construction supports conventional surface-mount assembly and tubing or reel-handling workflows. Because the published status is obsolete, procurement decisions should emphasize confirmed availability, original manufacturer traceability, and functional equivalence with the specific firmware and line-interface implementation.
Technically, the combination of a DAA function and multiple serial host interfaces allows the device to sit between a line-side codec or network termination path and an embedded controller. Parallel access can support legacy processor buses, while SPI and UART simplify connection to modern controllers. The 3.3 V-class supply also makes the device compatible with 3.3 V embedded systems, provided the associated clocking, reset, and interface levels comply with the system design.
Typical uses include legacy Voice over IP terminal designs, embedded voice bridges, telephone-line interface modules, and industrial telecom equipment that retains a Silicon Labs-compatible DAA architecture. Replacement work should verify not only voltage and package dimensions but also register behavior, interrupt timing, clock requirements, line-side integration, and the host firmware's expectations.
The principal design consideration is lifecycle risk: the SI3010-GS is listed as obsolete, so production continuity cannot be assumed. Engineers should obtain a controlled stock source, confirm the exact MPN and package, and validate any substitute against the manufacturer's SI3010 documentation before production release.
This page consolidates the verified supply range, package details, lifecycle information, interface capabilities, and qualified same-footprint alternatives into one engineering-focused record. It also distinguishes documented facts from missing electrical details, helping designers evaluate sourcing risk and replacement decisions without inferring unsupported pinout or performance data.

典型應用
SI3010-GS 適用於 6 應用s: Legacy Voice over IP Terminals, Telephone-Line Interface Equipment, Embedded Voice Bridges, Industrial Telecom Gateways, Customer Premises Equipment Repairs, Legacy Voice Access Gateway.
Legacy Voice over IP Terminals
The SI3010-GS fits a legacy Voice over IP terminal that already uses a Silicon Labs DAA architecture and needs a local subscriber-line interface. Its 3 V to 3.6 V operating range aligns with 3.3 V embedded systems, while the parallel, SPI, and UART interfaces provide options for connecting the DAA to a DSP, MCU, or voice codec. The 16-SOIC footprint is straightforward to place beside the line-side circuitry. Because the device is obsolete, its use is most defensible in an existing, proven design rather than a new product where long-term supply is required. A production release should include controlled original stock, firmware compatibility testing, and thermal checks across the specified 0°C to 70°C range.
推薦
Telephone-Line Interface Equipment
The SI3010-GS is appropriate for telephone-line interface equipment where a dedicated DAA separates line-side signaling from the host controller. Its documented 15 mA supply current and 3.3 V-class operation fit compact embedded voice products, while the 16-SOIC package permits conventional surface-mount routing. Parallel, SPI, or UART connectivity lets the design retain either a legacy host bus or a serial processor interface. Because the SI3010-GS is listed as obsolete, engineers should not introduce it into a new platform solely for a lower quoted price. The safer deployment is to preserve an already qualified circuit, verify every register and timing dependency, and plan a transition to an active SI3010-F-series candidate once equivalence testing is complete.
推薦
Embedded Voice Bridges
An embedded voice bridge can use the SI3010-GS when it must retain a DAA-based line interface while connecting to a modern embedded processor. The device's UART or SPI interface reduces parallel-bus wiring pressure, whereas the parallel option supports legacy controller architectures. Its specified 15 mA supply current helps constrain regulator sizing, and the 3 V to 3.6 V range matches a 3.3 V power domain. Designers should treat the obsolete status as a lifecycle risk and qualify the exact original part with traceable supply. Before production, compare the active SI3010-F-series alternatives for clock requirements, interrupt timing, register behavior, and host-driver changes; same-package compatibility alone does not establish firmware-level equivalence.
推薦
Industrial Telecom Gateways
The SI3010-GS can serve in an industrial telecom gateway or legacy voice gateway that already implements the required Silicon Labs DAA behavior. Its single-circuit implementation, 3.3 V-class supply, and choice of parallel, SPI, or UART host access allow integration with several processor styles, while the 0°C to 70°C rating targets indoor industrial environments. Lifecycle continuity remains the central concern: obsolete status can complicate long maintenance windows and component inspection. For an installed-system repair, original-device traceability and an exact fit qualification are more important than adopting a functionally similar but unverified substitute. For a new gateway, select an active SI3010-F-series option and verify temperature, timing, interface, and firmware requirements against the full manufacturer documentation.

Customer Premises Equipment Repairs
The obsolete SI3010-GS remains relevant for field repair of customer-premises equipment whose original bill of materials specifies that exact DAA device. Preserving the exact MPN can minimize PCB changes and avoid introducing unverified firmware or timing differences into equipment already deployed in the field. The 16-SOIC footprint supports replacement on existing boards, provided the incoming tube-packaged part is genuine and passes the buyer's inspection process. Procurement should document manufacturer, date code, traceability, inspection method, and quantity remaining. For long-term support programs, engineers should evaluate the active SI3010-F-series candidates as a longer-life roadmap, but validate them with the complete manufacturer datasheet and application circuitry rather than relying only on the shared package designation.
推薦
Legacy Voice Access Gateway
A legacy voice access gateway is a practical application for the SI3010-GS when the system requires a direct-access arrangement for line-side operation and already supports its parallel, SPI, or UART programming model. Its 15 mA supply current is modest for a telecom interface, and the 3 V to 3.6 V supply range integrates with a 3.3 V rail. The major engineering tradeoff is lifecycle rather than basic electrical fit: the component is obsolete, so availability may be finite and prices may reflect scarcity. A drop-in candidate in the same 16-SOIC footprint must still be tested for register compatibility, interrupt behavior, clocking, and firmware response. Production engineers should keep a documented last-time-buy strategy or transition plan alongside any original-stock procurement.

設計說明
Do not approve a substitute from package dimensions alone. Although the verified SI3010-F-series candidates use the same 16-SOIC format and are described as Direct Access Arrangement devices, verify supply voltage, current, clocking, reset behavior, interrupt timing, register compatibility, and supported host-interface modes against the complete manufacturer documentation. Existing firmware may depend on device behavior that is not captured in distributor summaries.
Budget the SI3010-GS from its specified 15 mA supply current and the application's 3 V to 3.6 V operating range. This is the device supply requirement, not a complete board power budget, so include host interfaces, codec circuitry, line drivers, and regulator efficiency separately. Ensure the selected regulator has appropriate transient margin and decouple the device supply locally with layout verified against the full SI3010 datasheet.
Preserve the original 16-SOIC footprint, copper, and assembly process when repairing an existing design. Confirm pin orientation against the manufacturer diagram rather than the incomplete search snippets. Because no verified machine-readable pin list was supplied for this record, do not infer pins from package orientation or standard SOIC numbering alone; use the manufacturer pinout and account for any exposed or connected land patterns on the assembled PCB.
Obsolete status requires a controlled sourcing plan. Record manufacturer, tube packaging, date code, traceability, inspection method, and remaining quantity for every purchase. Avoid mixing SI3010-GS with tape-and-reel SI3010-F candidates without confirming assembly orientation and feed-process requirements, and verify the exact active-device configuration before committing it to a long-lived production program.
