SI3210-KT Visão geral

The Silicon Labs SI3210-KT is a programmable CMOS ProSLIC subscriber line interface and codec with ringing and battery voltage generation, packaged in a 38-pin TSSOP. It is designed for wireline telephone interface applications and integrates a single-channel SLIC and codec function. The verified distributor information identifies the device as a telecom subscriber line interface circuit, while the product documentation describes the SI3210 family as a programmable CMOS SLIC/codec with ringing and battery voltage generation. The SI3210-KT operates from a 3.13 V minimum supply voltage to a 5.25 V maximum supply voltage, making it suitable for conventional telecom line-interface power environments where the exact rail conditions are compatible. Its 38-TSSOP package provides a defined surface-mount footprint for telecom line-card and subscriber-line equipment. The family is associated with Silicon Labs ProSLIC technology and is positioned for applications requiring integrated analog line termination, voice-channel processing, DTMF support, and line-power or battery-voltage generation functions. The available verified sources identify the SI3210-KT as a single-channel SLIC/codec with DTMF capability, but they do not provide the complete electrical limits, temperature range, clock requirements, pin names, or internal block-level timing values needed for a complete design specification. Consequently, the relevant parameters are identified as requiring confirmation from the manufacturer datasheet rather than being inferred. The SI3210-KT is best evaluated as a telecom interface IC for voice-over-copper equipment, line cards, subscriber line access designs, and related wired-communication products. Because its implementation depends on exact line impedance, battery voltage, ring cadence, codec timing, and host-control requirements, engineers should verify the complete datasheet, pinout, application circuit, and operating limits before releasing production hardware.

Aplicações típicas

SI3210-KT é adequado para 6 aplicaçãos: Voice-over-Copper Terminals, Subscriber Line Access Equipment, Telephone Line Cards, Central Office Voice Interfaces, VoIP Analog Line Adapters, DTMF-Enabled Telephone Equipment.

🌐

Voice-over-Copper Terminals

The SI3210-KT fits voice-over-copper terminals because it combines a single-channel subscriber line interface, codec, DTMF support, ringing voltage generation, and battery voltage generation in one 38-TSSOP device. Its verified 3.13 V to 5.25 V supply range supports conventional telecom line-card supply environments. Using an integrated ProSLIC reduces the number of separate line-interface functions that must be coordinated, although the designer must confirm line impedance, ring waveform, off-hook current, and codec timing in the complete manufacturer datasheet.

🏭

Subscriber Line Access Equipment

The SI3210-KT is suitable for subscriber line access and line-card equipment because the device integrates the SLIC and codec functions required at the analog telephone-line boundary. Its supported 3.13 V to 5.25 V supply range and integrated 38-TSSOP package provide a defined basis for compact line-card designs. Ringing and battery voltage generation are especially relevant to line termination, while DTMF support assists signaling. Before schematic release, engineers should verify line-drive limits, external protection requirements, host interface behavior, and thermal performance.

📞

Telephone Line Cards

The SI3210-KT can serve as the subscriber line interface on a telephone line card where a single analog voice channel must terminate a copper pair. Its integrated ringing and battery voltage generation support the line-side power conditions associated with idle, ring, and off-hook states, while the codec provides the voice conversion function. The 38-TSSOP footprint supports conventional surface-mount assembly. Because the supplied evidence omits exact current limits, timing, and pin definitions, the reference design and datasheet must be used to finalize protection and routing.

🏢

Central Office Voice Interfaces

The SI3210-KT is applicable to central-office voice interfaces that require an integrated analog subscriber-line termination with codec support. Combining the SLIC, codec, DTMF, ringing generation, and battery generation functions can reduce board complexity compared with separate line-interface blocks. Its verified 3.13 V to 5.25 V operating range should be checked against the central-office rail plan. The complete implementation must also account for surge protection, line impedance, codec synchronization, and the device-specific application circuit.

📱

VoIP Analog Line Adapters

The SI3210-KT fits an analog line adapter used to bridge a VoIP endpoint to a copper telephone network because it combines the line-side interface and voice codec in a single component. DTMF handling, ringing generation, and battery voltage generation cover key PSTN-facing functions, while the single-channel configuration matches one-line adapters. The 3.13 V to 5.25 V supply range and 38-TSSOP package support compact embedded designs. Final validation should include echo-path behavior, ring cadence, off-hook loading, and host-control timing.

🔧

DTMF-Enabled Telephone Equipment

The SI3210-KT is appropriate for DTMF-enabled telephone and signaling equipment because the verified listing explicitly identifies DTMF capability in the integrated single-channel SLIC/codec. Combining DTMF handling with ringing and battery voltage generation can simplify a line-facing design while retaining a dedicated analog termination function. The device is supplied in a 38-TSSOP package for surface-mount assembly. Engineers should still confirm the supported tone modes, detection thresholds, codec clocking, and line-state behavior using the complete manufacturer documentation.

What is the SI3210-KT?
The SI3210-KT is a single-channel programmable CMOS ProSLIC subscriber line interface and codec with ringing and battery voltage generation. Silicon Labs describes the SI3210 family as a ProSLIC telecom interface IC, and the verified distributor listing identifies the SI3210-KT as a Subscriber Line Interface Concept (SLIC) and codec in a 38-TSSOP package. It is intended for wired telecom line-interface equipment.
What is the operating voltage of SI3210-KT?
The SI3210-KT operates from 3.13 V to 5.25 V according to the verified component comparison data. That range identifies the supported supply-voltage boundaries, but the complete datasheet should still be checked for normal operating conditions, tolerances, absolute maximum ratings, and power-supply sequencing before the device is used in a new design.
What package does the SI3210-KT use?
The SI3210-KT uses a 38-TSSOP package. The package is identified consistently in the verified distributor listing and comparison data as TSSOP-38, also described as a 38-TFSOP-style package. Because this is a fine-pitch leaded package, board layout should follow the manufacturer land pattern and the exact pin numbering shown in the official datasheet.
Where can I download the SI3210-KT datasheet PDF?
The SI3210-KT datasheet can be accessed through the Silicon Labs product documentation pages and the verified SI3210 datasheet links, including the datasheet listing at datasheets.com and the manufacturer-family document at datasheet4u.com. The available search results identify the SI3210 documentation as a 37-page ProSLIC datasheet, but engineers should use the current official manufacturer copy for release-controlled documentation.
Where can I find the SI3210-KT pinout?
The SI3210-KT pinout is available in the manufacturer SI3210 ProSLIC datasheet and its associated package-drawing section. The verified web results identify the device as a 38-TSSOP and provide links to pinout documentation, but no complete authoritative pin-number-to-signal table was included in the supplied data. The complete pinout is therefore not reproduced here and must be verified before PCB routing.
Does the SI3210-KT support DTMF?
Yes. The verified product listing describes the SI3210-KT as a single-channel SLIC and codec with DTMF capability. DTMF support is useful in telephone line-card and subscriber-line designs because it allows the interface circuit to handle dual-tone multifrequency signaling within the integrated telecom signal path. Exact tone-generation and detection limits should be confirmed in the full datasheet.
Does the SI3210-KT include ringing and battery voltage generation?
Yes. The manufacturer-family description identifies the SI3210 as a programmable CMOS SLIC/codec with ringing and battery voltage generation. These functions are central to subscriber-line termination because they support the line-side voltage requirements associated with ring signaling and off-hook battery power. The exact ring waveform, battery regulation, and line-drive limits require the complete datasheet.
Where can I buy SI3210-KT online?
The SI3210-KT can be sourced through the verified DigiKey listing at digikey.com and through the Octopart distributor aggregation page. The verified search data does not provide a current unit price, stock count, or guaranteed lead time, so those commercial values must be confirmed at the distributor before purchase. The Octopart result lists comparisons across 14 distributors.
What is the price of SI3210-KT?
The supplied verified data does not expose a numeric SI3210-KT unit price. The DigiKey and Octopart pages provide the relevant purchasing paths and distributor comparisons, but no price was included in the retrieved snippets. Pricing should therefore be checked live as of 2026-10-28 rather than relying on an unverified estimate, and volume pricing may vary by order quantity.
What is the lead time for SI3210-KT?
The SI3210-KT lead time is not stated in the supplied verified data. The DigiKey result says that the part is available for purchase, but the snippet does not provide a dated stock quantity, factory lead time, or minimum order quantity. Confirm current availability and lead time with the selected authorized distributor as of 2026-10-28.
Is the SI3210-KT in stock?
The verified DigiKey listing states that the SI3210-KT can be bought and shipped, but it does not include a numeric stock level or a formal InStock field. For that reason, the product offer is represented as BackOrder rather than claiming a specific inventory quantity. Check the distributor page for the current stock position before committing a build schedule.
What is the best drop-in replacement for SI3210-KT?
SI3210-GT is the closest verified same-footprint alternative identified in the supplied cross-reference data. It is listed as a 38-TSSOP telecom SLIC/codec with the same 3.13 V to 5.25 V supply-voltage range. However, the supplied sources do not establish every pin function, firmware, line-performance, and lifecycle detail, so engineers should validate the manufacturer comparison and complete datasheets before using it as a drop-in replacement.
Can SI3210-FT replace SI3210-KT?
SI3210-FT is a same-family candidate for replacement review because the verified comparison page lists it in the same 38-TSSOP package and the same 3.13 V to 5.25 V supply range. Pin-to-pin electrical equivalence is not fully established by the supplied snippets, so replacement approval should depend on a manufacturer or distributor cross-reference, pin comparison, and firmware or host-interface review.
What can replace SI3210-KT?
SI3210-GT and SI3210-FT are the only replacement candidates supported by the supplied web evidence, and both use the 38-TSSOP package shown for the SI3210-KT. The available data also mentions SI3211, SI3212, and SI3213 as related ProSLIC-family products, but it does not verify their package or pin compatibility. Consequently, no additional part should be called a drop-in replacement without a complete cross-reference.
SI3210-KT vs SI3210-GT: which is better for a telecom line card?
SI3210-GT is the stronger verified replacement candidate because it is compared with SI3210-KT using the same 38-TSSOP package and 3.13 V to 5.25 V supply range. SI3210-FT is another same-package family candidate, but the supplied evidence does not identify functional differences. For an existing SI3210-KT design, SI3210-GT should win only after pin, electrical, firmware, and application-circuit compatibility are confirmed.
When should I choose SI3210-KT over SI3210-GT?
Choose SI3210-KT when the design is already qualified around its specific device revision, host-control configuration, line parameters, and approved bill of materials. SI3210-GT is preferable only when sourcing support or lifecycle continuity requires a documented alternative and its complete technical comparison shows no functional change. The supplied data confirms matching package and supply-voltage boundaries but does not establish full equivalence.
Is the SI3210-KT suitable for voice-over-copper equipment?
Yes, the SI3210-KT is specifically suited to voice-over-copper and related subscriber-line equipment because it integrates a SLIC, codec, DTMF capability, ringing generation, and battery voltage generation in one 38-TSSOP device. It is a better fit than a generic codec when the design requires integrated line termination. Production use still depends on validating line impedance, codec timing, ring voltage, and battery current against the complete datasheet.
What are the key specifications of SI3210-KT that engineers should know?
The SI3210-KT is a single-channel programmable CMOS ProSLIC SLIC/codec in a 38-TSSOP package, with a verified supply range of 3.13 V to 5.25 V. Its headline functional features are integrated ringing voltage generation, battery voltage generation, and DTMF support. The verified data does not expose complete current consumption, temperature range, pin mapping, codec clock, or line-drive ratings, so those items require manufacturer-datasheet confirmation.

Notas de projeto

Design the supply rails around the verified 3.13 V to 5.25 V SI3210-KT operating range and reserve headroom for ringing and battery-generation circuitry. Confirm whether the system supplies the line-related voltages externally or derives them according to the manufacturer application circuit. Use local high-frequency bypass capacitors close to the supply pins and validate startup, shutdown, and power-consumption behavior against the full datasheet.

Use the manufacturer 38-TSSOP land pattern and maintain short, direct connections for supply, ground, analog line, and codec-related signals. Place protection components associated with the external telephone-line connection at the board edge, while keeping high-energy transient current away from sensitive codec and control circuitry. Verify pin numbers against the official datasheet because the complete pinout was not available in the supplied source data.

Do not treat a same-package family member as a guaranteed drop-in replacement. SI3210-GT and SI3210-FT share the 38-TSSOP package and 3.13 V to 5.25 V supply range in the verified comparison pages, but replacement approval must also check line-drive limits, DTMF behavior, ringing and battery functions, codec timing, firmware configuration, and lifecycle status.

Treat the analog line interface as a potentially noisy environment and keep the SLIC, codec, clocking, and host-control sections appropriately partitioned. Follow the manufacturer reference layout for grounding and decoupling, and keep external line-protection paths away from sensitive signal nodes. EMI and ringing-performance testing should be performed at the intended line voltage, current, and cable length because the supplied snippets do not provide detailed conducted-emissions limits.
