SI3010-KS - 3.3V Global Serial DAA | Silicon Labs | Telecom
MPN: SI3010-KS ✓ ActiveSI3010-KS Overview
A direct access arrangement, or DAA, is a semiconductor interface that connects a digital communications system to an analog telephone line. In the broader hierarchy, a DAA belongs to the telecommunications interface class, which sits within interface ICs and broader semiconductor solutions. Instead of implementing every line-side function with separate analog, isolation, switching, and signal-conditioning components, a DAA IC consolidates those functions into a controlled silicon interface.
The SI3010-KS operates from a 3 V to 3.6 V supply and is identified by distributor listings as a single-circuit telecom DAA. Its available interface choices include parallel, SPI, and UART, giving the system designer several host-bus options for registering, configuration, and line-status monitoring. The listed operating current of 15 mA provides a concrete power figure for preliminary 3.3 V rail budgeting in compact telecom equipment.
The device is supplied in a 16-SOIC package measuring 3.90 mm in body width. Distributor records identify both tube packaging and surface-mount construction, while the package family remains SOIC, a surface-mount technology also known as small-outline integrated circuit packaging. The 16-pin arrangement supports a relatively compact land pattern compared with larger leaded telecom-interface packages.
Typical uses include Voice over IP subscriber terminals, analog telephone adapters, customer premises equipment, embedded voice systems, and other products that must bridge a digital controller with a telephone line. The exact line-side operating modes, country-specific network requirements, and host protocol details should be confirmed in the manufacturer datasheet before production release.
Design planning must account for the 3.3 V supply tolerance, the 15 mA current requirement, the analog telephone-line environment, and the need for correct external protection and hook-related circuitry. Because a DAA is safety- and network-interface sensitive, PCB routing, isolation boundaries, surge exposure, and regulatory requirements should be reviewed as a complete design rather than treated as a generic serial-interface layout.
This product record combines verified distributor specifications, package information, cross-reference results, drop-in replacement analysis, application guidance, and design considerations. It highlights where the SI3010-KS matches the published SI3010-F-FSR comparison data and clearly identifies parameters that remain unverified rather than estimating unsupported electrical details.

Typical Applications
SI3010-KS is suitable for 6 applications: Voice over IP Terminals, Analog Telephone Adapters, Customer Premises Equipment, Embedded Voice Systems, Industrial Telecom Gateways, Analog Line Interface Cards.
Voice over IP Terminals
The SI3010-KS fits a Voice over IP terminal that needs a compact telephone-line interface alongside a digital voice processor. Its 3 V to 3.6 V operating range aligns with 3.3 V embedded systems, while Parallel, SPI, and UART options provide flexibility in host connectivity. According to the manufacturer datasheet, the integrated DAA replaces a discrete analog front end, isolation transformer, relays, opto-isolators, and a 2-wire to 4-wire hybrid. That consolidation can reduce board area and assembly complexity. The 15 mA listed operating current should be included in the line-interface power budget, while the final design must verify the required country-specific line modes, hook behavior, protection network, and regulatory isolation requirements.
Recommended
Analog Telephone Adapters
The SI3010-KS is suitable for an analog telephone adapter in which a digital processor must bridge to a conventional telephone network. The single-circuit DAA architecture can replace several discrete line-side blocks, potentially simplifying the PCB and reducing assembly cost. Its 16-SOIC package provides a compact surface-mount solution, while the 3 V to 3.6 V range supports a 3.3 V system supply. Parallel, SPI, and UART host interfaces make the DAA adaptable to different controller architectures. Before release, designers should confirm line-mode support, line impedance, ring detection, off-hook behavior, surge exposure, and all applicable network-approval and safety requirements from the complete manufacturer documentation.
Recommended
Customer Premises Equipment
The SI3010-KS can serve customer premises equipment that combines embedded processing with a telephone-line connection. Its single-circuit DAA provides a programmable global line interface, and the manufacturer datasheet indicates that it eliminates several separate analog and isolation components. This can shorten the analog design cycle while preserving multiple host-interface choices. The verified 3.3 V supply range and 15 mA listed current support early power planning, and the 16-SOIC package keeps the land pattern compact. In a deployed CPE product, however, the engineering team must still validate ringing voltage tolerance, line-state transitions, isolation strategy, protection components, regional line modes, and the complete recommended application circuit before production.
Recommended
Embedded Voice Systems
The SI3010-KS is appropriate for an embedded voice system that requires a dedicated telephone-line interface rather than a general-purpose serial transceiver. Its selectable Parallel, SPI, and UART connections allow the designer to match the host controller and firmware architecture. According to the manufacturer datasheet, the programmable line interface consolidates functions otherwise implemented with an analog front end, isolation transformer, relays, opto-isolators, and a hybrid. The 16-SOIC package is practical for compact embedded hardware, and the 3 V to 3.6 V range integrates with a 3.3 V rail. Digital timing, host register definitions, line-side operating modes, and country-specific behavior must be verified from the exact manufacturer documentation.
Recommended
Industrial Telecom Gateways
The SI3010-KS may be used in an industrial telecom gateway that bridges a digital data network and a telephone line. The integrated DAA offers a path to reduce external component count compared with a discrete line-side implementation, while parallel, SPI, and UART connectivity supports diverse embedded gateways. The 16-SOIC surface-mount package supports compact board construction, and the listed 15 mA operating current is suitable for early rail budgeting. Industrial use does not remove line-interface risks: designers must account for temperature limits, surge and transient exposure, protective networks, isolation, grounding, regulatory approvals, and the supported operating modes. Those details were not present in the supplied snippets and must be obtained from the full manufacturer datasheet.
Recommended
Analog Line Interface Cards
The SI3010-KS can be integrated into a modular analog line interface card when each channel requires a dedicated DAA and the controller can use one of the supported host buses. The 16-SOIC package keeps each channel compact, and the 3 V to 3.6 V range matches conventional 3.3 V interface-card rails. Its parallel, SPI, and UART options can simplify integration with different line controllers, while the manufacturer datasheet indicates that the DAA replaces several discrete line-side components. Multi-channel designs must carefully allocate supply decoupling and routing so switching from adjacent circuitry does not degrade telephone-line behavior. Spacing, isolation, protection, thermal conditions, firmware configuration, and all line modes must be validated for the intended deployment and applicable network rules.

- Broad documented supply range (vs SI3010-F-FSR)
Design Notes
Design the SI3010-KS around its verified 3 V to 3.6 V operating range and listed 15 mA operating current. Keep the 3.3 V supply within the manufacturer's absolute limits and use local high-frequency decoupling at the supply pins. Because the supplied excerpts do not include ripple, transient, maximum-current, or power-consumption limits, these values must be taken from the full datasheet before setting regulator capacity. The estimated worst-case dissipation using only the listed 15 mA at 3.6 V is 54 mW, excluding external line-interface losses and regulator overhead.
Treat the DAA and its telephone-line circuitry as a high-level isolation and signal-integrity boundary rather than as an ordinary serial port. Follow the manufacturer application layout exactly, including analog and digital partitioning, protection placement, isolation components, and line-side return paths. Route sensitive host signals away from switching nodes and surge paths, and provide a solid ground reference as specified in the datasheet. The verified snippets do not provide trace widths, spacing, or creepage distances, so no unsupported layout dimensions are asserted here.
Do not assume that two devices in 16-SOIC packages are pin-compatible merely because their packages match. The SI3010-F-FSR comparison shows a plausible DAA replacement candidate, but the supplied evidence does not include its complete pin table, register map, or country-specific line modes. Before substituting it for the SI3010-KS, compare every supply, ground, host-interface, hook, ring, and analog line-side connection and then retest line states, timing, EMI, and protection behavior.
Verify the production package and pin mapping against the current manufacturer documentation before releasing artwork or purchasing quantities. The verified records consistently identify SI3010-KS as a 16-SOIC device and list tube packaging, but the individual pin names were not available in the supplied snippets. Also confirm reel or tube ordering options directly with the distributor, because the product record represents only the packaging option explicitly listed in the supplied source.
Compliance Information
The supplied SI3010-KS excerpts do not explicitly state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. A RoHS details field appears for the SI3010-F-FSR comparison record, but it was not applied to the target part. AEC-Q100 is not applicable to this telecom interface IC.
