SI3200-BS - Dual-Channel 100V Programmable SLIC | Skyworks
부품 번호: SI3200-BS ✓ 활성SI3200-BS 개요
A Subscriber Line Interface Circuit, or SLIC, is an integrated circuit that interfaces a central-office or digital-signaling system with an analog telephone line. In the hierarchy of electronic components, a SLIC is a telecom interface IC within the broader interface-IC and semiconductor categories. It combines linefeed control, ringing generation, speech-path signaling, line monitoring, and programmable voice-channel functions so customer-premise equipment can connect to the public switched telephone network.
The SI3200-BS provides two independently programmed line channels in one package. According to the manufacturer datasheet information supplied for this part, its principal features include balanced ringing to 65 Vrms, low standby power consumption below 65 mW per channel, 100 V linefeed operation, and software-programmable ringing frequency and related line parameters. These characteristics make it relevant to analog telephone adapters, voice over broadband terminals, customer-premise equipment, and other dual-line voice products.
The device uses a mixed-signal architecture in which low-voltage CMOS logic controls high-voltage analog telephone functions. Its 3.3 V or 5 V supply operation allows the digital control section to operate from conventional logic rails, while the high-voltage linefeed section supports battery feed up to 100 V. Two channels per package can reduce board area, but each channel still requires protection, hook-state detection, line termination, and external circuitry appropriate to the telephone application.
Typical uses include dual-channel analog telephone interfaces, voice-over-IP terminal linecards, small-business phone systems, CPE line-monitoring circuits, and telecom equipment requiring a programmable SLIC. The SI3200-BS is also suited to designs that need 65 Vrms balanced ringing while limiting standby consumption. Its dual-channel organization is particularly useful when two independent telephone lines must share one linefeed IC.
Designers should use the manufacturer datasheet and application information to verify external component values, line-state thresholds, ringing waveforms, protection requirements, and thermal margins. The 100 V linefeed capability does not eliminate the need for surge protection, correct isolation boundaries, adequate copper creepage, and controlled layout around high-voltage nodes. Availability, detailed pricing, and exact operating-temperature limits were not supplied in the verified data and must be confirmed before release to production.
This page consolidates the verified linefeed, power, packaging, and programmability information with engineering guidance, comparison parameters, and application analysis. It distinguishes documented capabilities from unavailable specifications, helping engineers evaluate the SI3200-BS without treating distributor search results as a substitute for the manufacturer datasheet.

Analog Telephone Adapter
The SI3200-BS is appropriate for an analog telephone adapter that must preserve a conventional telephone line while providing digital voice connectivity. Its two channels support two lines in one 16-pin SOIC package, while 100 V linefeed capability and balanced ringing to 65 Vrms address the high voltages used by analog telephone networks. According to the verified manufacturer-datasheet information, the device also operates from 3.3 V or 5 V and consumes less than 65 mW per channel in standby. The external design must still include the required line protection, hook detection, DC feed, and ringing network, with high-voltage spacing maintained throughout the PCB layout.

Customer Premise Equipment
The SI3200-BS fits customer-premise equipment requiring two controllable analog line channels in a compact surface-mount package. Its software-programmable ringing frequency and line parameters allow a common platform to configure behavior for different network deployments, while the dual-channel architecture reduces the number of linefeed ICs compared with one device per line. According to the verified datasheet description, standby consumption is below 65 mW per channel and low-voltage operation is available from 3.3 V or 5 V. The design should confirm exact line-state thresholds, external component values, and protection requirements against the current manufacturer documentation before production release.

Voice over IP Terminal
A voice-over-IP terminal can use the SI3200-BS when it must connect digital voice processing to one or two analog telephone lines. The SLIC handles the high-voltage linefeed and ringing side, while a separate codec and processor handle voice conversion. According to the verified manufacturer information, the SI3200-BS supports two programmable channels, 65 Vrms balanced ringing, and 100 V linefeed operation, making it suitable for dual-line CPE. Its 3.3 V or 5 V control supply simplifies integration with modern digital logic, although complete suitability still depends on matching the terminal's hook-state circuitry, line impedance, and regional telephone-network requirements.

Small Business Telephone System
The SI3200-BS can serve as the linefront-end IC in a small-business telephone system that supports two analog lines per device. Consolidation of two programmable SLIC channels into one 16-pin SOIC can simplify routing and reduce PCB area compared with two separate single-channel devices. According to the verified manufacturer-datasheet information, each channel supports 100 V linefeed operation and balanced ringing to 65 Vrms, while standby consumption remains below 65 mW per channel. A practical implementation must still provide surge protection, ring-voltage compliance, line isolation or grounding as required, and careful separation between high-voltage and logic domains.
추천
Telephone Line Monitoring Circuit
The SI3200-BS is suitable for line-monitoring functions because it combines programmable SLIC operation with integrated line monitoring in a dual-channel device. According to the verified manufacturer datasheet description, software-controlled line parameters and 100 V linefeed capability allow equipment to supervise the telephone line and distinguish operating states required by CPE designs. Its standby power below 65 mW per channel is useful where continuous line presence is required without excessive standby consumption. Exact monitoring thresholds, hook-state behavior, and test-access details are not included in the supplied snippets and must be confirmed in the current datasheet before firmware or PCB decisions are finalized.
추천
Dual-Line Voice Card
The SI3200-BS is well matched to a dual-line voice card where two independently programmable telephone interfaces are required. According to the verified manufacturer-datasheet information, the 16-pin SOIC device combines two channels, 100 V linefeed capability, and balanced ringing to 65 Vrms in one package. The 3.3 V or 5 V supply option allows the low-voltage section to share common system rails, while single or dual battery operation supports the linefeed domain. Board layout should maintain the required high-voltage clearance, place protection devices close to the line connector, and isolate ringing and DC-feed paths from sensitive audio and digital circuitry.

설계 노트
Separate the low-voltage logic supply from the high-voltage telephone-line feed when planning the power architecture. According to the manufacturer information supplied in the verified results, the SI3200-BS supports 3.3 V or 5 V operation as well as single or dual battery supplies up to 100 V. Confirm the exact supply rails, sequencing, bypass-capacitor values, and permitted supply combinations against the current datasheet because those details were not included in the verified snippets.
Treat every line-connected node as a high-voltage area even though the SI3200-BS uses a compact 16-pin SOIC. Keep the linefeed, ringing, and protection components away from low-level audio, processor, and codec traces; preserve the package spacing and copper-clearance requirements specified by the manufacturer. Place surge-protection devices close to the external line connector and use a controlled ground strategy for the telephone-line interface.
Do not treat the 65 Vrms balanced-ringing figure as permission to omit external ringing-network, hook-state, line-termination, or protection components. The verified SI3200 family information identifies 100 V linefeed capability, 65 Vrms ringing, and programmable parameters, but it does not provide the full application circuit or complete pin map. Use the manufacturer reference design to reproduce those functions and verify board-level ring voltage rather than relying on a nominal description alone.
Validate thermal performance using the actual ringing duty cycle, line-feed voltage, board copper area, and enclosure temperature. The verified data establishes a 100 V linefeed capability and a 16-pin SOIC package but supplies no thermal resistance, maximum junction temperature, or allowed dissipation. Those figures are necessary for a production thermal calculation and must be obtained from the current manufacturer datasheet before operating continuously near the highest supported line voltage.
