SI3019-KS - Global DAA Telecom Interface IC | Skyworks Solutions
Référence : SI3019-KS ✓ ActifSI3019-KS Présentation
A Direct Access Arrangement, or DAA, is the line-side interface between a communications system and the public telephone network. It belongs to the telephone-interface IC hierarchy, which combines network-interface signaling, voice-path processing, codec functions, and line termination. By integrating an AC termination function, DC termination function, ring-detect threshold, ringer impedance, and codec interface with a four-wire hybrid, the SI3019-KS consolidates several functions normally distributed across a line-card design.
The SI3019-KS supports GCI, PCM, and SPI interfaces, providing flexible connectivity between the DAA and the surrounding line-processing equipment. Its documented supply-voltage range is 3 V to 3.6 V, while current consumption is listed as 8.5 mA. These characteristics suit low-voltage telecom systems in which a direct-access arrangement must combine signaling control and a voice path in a compact, surface-mount package.
Within the device, the integrated codec and four-wire hybrid separate transmit and receive voice signals from the line-facing network path. The 80 dB dynamic-range specification provides a quantitative indication of the available voice-path signal range. AC and DC termination functions support the physical line interface, while the ring-detect threshold and ringer-impedance functions help the surrounding system interpret line-state conditions.
Typical uses include telephone line cards, customer premises equipment, private-branch exchange interfaces, voice gateways, central-office line cards, and industrial telecommunications equipment. In these systems, the SI3019-KS can manage the line-side termination and signaling interface while GCI, PCM, or SPI connects the device to digital line-processing circuitry.
Designers should confirm the complete pin mapping, absolute electrical limits, line-impedance requirements, and timing details against the manufacturer datasheet before layout release. Decoupling, analog-signal routing, hybrid-network isolation, and grounding are especially important because the device combines digital control interfaces with sensitive line-side voice functions.
This page consolidates verified distributor specifications, lifecycle-related sourcing information, same-family replacement candidates, and application guidance. Because the supplied web results do not expose the full manufacturer datasheet, pin list, detailed electrical table, or numeric distributor price breaks, those items are explicitly marked for verification rather than inferred.

Applications typiques
SI3019-KS convient pour 6 applications: Telephone Line Cards, Customer Premises Equipment, Voice Gateways, Private Branch Exchange Interfaces, Industrial Voice Communications, Central Office Line Equipment.
Telephone Line Cards
The SI3019-KS fits a line-card implementation that requires a dedicated line-side interface alongside digital processing. Its integrated AC and DC termination, ring-detect threshold, and ringer impedance reduce the number of discrete line-state functions, while the codec and four-wire hybrid support the voice path. The 3 V to 3.6 V operating range, 8.5 mA consumption, and GCI, PCM, or SPI connectivity allow the same device class to fit multiple telecom board architectures. Before layout release, verify the exact pin functions, line impedance values, protection requirements, and manufacturer reference circuit.
Recommandé
Customer Premises Equipment
The SI3019-KS is appropriate for customer premises equipment that interfaces a voice line with digital baseband circuitry. Its integrated codec and four-wire hybrid establish the voice channels, and the 80 dB TX/RX dynamic range provides a defined operating target. GCI, PCM, and SPI interfaces let the design connect the DAA to different controller arrangements rather than locking into one digital interface. The 16-SOIC package supports conventional surface-mount assembly, although the device's supplied lead and RoHS status must be considered during regulatory qualification.
Recommandé
Voice Gateways
A voice gateway can use the SI3019-KS as the line-facing DAA while a system processor handles call control and digital audio processing. The available GCI, PCM, and SPI interfaces support different gateway signal paths, and the integrated termination functions reduce external line-interface circuitry. Its 3 V to 3.6 V supply range aligns with low-voltage embedded systems, while 8.5 mA consumption helps control board-level power demand. Engineers should still calculate margins for adjacent codecs, protection devices, and ringing circuitry, and should verify clocking, framing, and electrical limits in the complete datasheet.
Recommandé
Private Branch Exchange Interfaces
The SI3019-KS can support line-card or trunk-interface sections of a private branch exchange where integrated termination and voice-channel functions simplify board partitioning. Its V.92 data format and 80 dB TX/RX dynamic range establish the principal line-interface characteristics, while the three digital interfaces provide flexibility in connecting the DAA to switching logic. Because the line impedance and termination implementation are manufacturer-specific, the device should be placed according to the reference schematic rather than inferred solely from the integrated-function list.
Recommandé
Industrial Voice Communications
The SI3019-KS can be evaluated for industrial voice terminals, intercom equipment, and communications equipment that connects a telephone-network line to embedded control electronics. Its compact 16-SOIC format preserves board area, and the integrated termination, ring detection, ringer impedance, codec, and four-wire hybrid consolidate several line-interface functions. The 8.5 mA consumption and 3 V to 3.6 V supply support constrained embedded power designs. Deployment should be conditioned on the required line impedance, environmental temperature range, isolation requirements, and applicable regulatory approvals.
Recommandé
Central Office Line Equipment
The SI3019-KS is suitable for line-side sections of central-office and voice-access equipment where a compact DAA can combine termination, codec, and hybrid functions. Its V.92 format, 80 dB dynamic range, and GCI, PCM, and SPI interfaces provide a flexible bridge between the analog line and digital switching circuitry. The 16-SOIC package simplifies PCB footprint planning compared with multi-component implementations, but production use requires confirmation of the complete pinout, timing, line parameters, and fault limits. Tube packaging is the documented shipping format for the SI3019-KS.

Principaux différenciateurs
- Three digital interface options in one DAA (vs SI3019-F-GS)
- Documented TX/RX dynamic range (vs SI3019-FT)
- Integrated line-state and voice functions (vs SI3019-F-FSP)
Notes de conception
Separate the line-side and voice-path copper from SPI, GCI, and PCM routing as specified by the manufacturer reference layout. The SI3019-KS combines sensitive line termination, a codec, and a four-wire hybrid, so long digital traces, switching-node proximity, and discontinuous ground paths can degrade performance. Confirm the complete pin assignments before fixing the component orientation and keep analog and digital return currents separated where the datasheet provides separate ground connections.
Design the SI3019-KS supply network around the documented 3 V to 3.6 V operating range and 8.5 mA device consumption. Place local decoupling at the supply pins and verify the capacitor type, voltage rating, and effective capacitance against the manufacturer's application circuit. Because the supplied results do not include ripple, absolute maximum ratings, or recommended capacitor values, those items must be obtained from the complete datasheet rather than estimated.
Do not treat every SI3019 suffix as automatically interchangeable. The substitute search identifies SI3019-F-GS, SI3019-FT, and SI3019-F-FSP as family candidates, but the source states that precise cross-referencing requires manufacturer documentation. Compare pin names, exposed functions, line impedance, supply limits, timing, temperature grade, and ordering information before replacing SI3019-KS; a common family name alone does not establish drop-in compatibility.
Informations de conformité
Verified product information states that the SI3019-KS is RoHS non-compliant and contains lead. REACH, AEC-Q100, halogen-free, and conflict-minerals information was not present in the supplied results.
