SI3210-BT - Programmable SLIC/CODEC with Ringing | Skyworks
MPN: SI3210-BT ✗ סוף ייצורSI3210-BT סקירה
A SLIC is an interface IC that connects a digital communications system to an analog telephone line. Typical SLIC functions include DC feed, line termination, ring voltage generation, line supervision, codec conversion, tone generation, and caller-ID signal handling. By placing these functions in a programmable CMOS device, the SI3210-BT allows system designers to adapt line behavior through manufacturer-defined control registers rather than using a large collection of discrete telephone components.
The SI3210/Si3211 family supports software-configurable ringing with up to five REN and 90 VPK, along with DTMF generation and decoding and Caller ID generation. These capabilities make the family applicable to analog telephone adapters, voice-over-IP terminal equipment, digital subscriber line terminal designs, customer-premises equipment, and other line-powered telecom products. The family documentation also describes comprehensive telephony signaling support for global operation.
The SI3210-BT is identified in comparison data as a one-channel SLIC with 60 dB performance and approximately 41 mA operation from 3.3 V or 5 V supplies. The -BT suffix denotes the 38-pin TSSOP ordering option. Because the SI3210-BT is marked obsolete, engineers should confirm availability, lifecycle expectations, and the exact package drawing before beginning a new production design.
A robust line-interface design must account for high ringing voltage, transient protection, hook-state transitions, analog isolation, and PCB creepage. The ring generator can reach 90 VPK, so external protection and insulation coordination are essential even though the ringing function is integrated. Firmware configuration and production test should also be treated as part of the product design rather than treating the IC as a fixed-function codec.
This page consolidates verified family specifications, sourcing links, package constraints, and practical line-interface guidance. It also distinguishes the documented SI3210 options from unverified assumptions, helping engineers evaluate obsolete inventory without presenting it as a currently recommended new-design choice.

יישומים טיפוסיים
SI3210-BT מתאים עבור 6 יישוםs: Voice-over-IP Telephone Adapter, Analog Terminal Adapter, Caller-ID Telephone, Digital Subscriber Line Terminal, Line-Powered Fax and Data Terminal, Embedded Voice Communication Controller.
Voice-over-IP Telephone Adapter
The SI3210-BT fits a VoIP telephone adapter because it combines a one-channel SLIC, codec, ringing generation, battery-voltage generation, DTMF handling, and Caller ID generation in a single 38-pin TSSOP device. The verified family comparison identifies approximately 41 mA operation, 60 dB performance, and support for 3.3 V or 5 V supplies. In a design, the SLIC connects to the analog line through the required external network while the digital side interfaces with the voice processor. The 90 VPK ring capability reduces the need for a separate basic ring generator, although transient protection and insulation coordination remain necessary. Because the SI3210-BT is obsolete, an existing validated design can preserve it, while a new product should compare currently supported family options before committing.
מומלץ
Analog Terminal Adapter
The SI3210-BT is appropriate for an analog terminal adapter requiring an integrated telephone-line interface in a compact surface-mount package. Its software-configurable ringing supports up to 5 REN at 90 VPK, while DTMF generation and decoding and Caller ID generation cover common on-hook and off-hook signaling functions. The device can be placed beside the line transformer or coupling network, with its digital control interface connected to the system controller. Using a 3.3 V or 5 V supply provides design flexibility, although the approximately 41 mA comparison current must be included in the power budget. The obsolete status is the principal constraint for new equipment, so engineers should validate lifecycle availability and consider a documented SI3210-family alternative.
מומלץ
Caller-ID Telephone
The SI3210-BT can support a Caller-ID telephone because the manufacturer family documentation specifically lists Caller ID generation together with programmable ringing, DTMF generation, and DTMF decoding. Its one-channel line architecture allows a telephone design to combine voice, keypad tones, ring generation, and subscriber signaling in one 38-pin TSSOP device. The external line interface must still handle the 90 VPK ring waveform, hook-state transitions, and transient protection. System software can configure the relevant signaling behavior through the device control interface, reducing discrete telephone circuitry. For a product currently in production, the SI3210-BT can be retained only with a controlled supply plan; for a new design, lifecycle status and support for the required signaling profiles should take priority over package reuse alone.
מומלץ
Digital Subscriber Line Terminal
The SI3210-BT can serve as the analog voice line interface in a digital subscriber line terminal that also requires ringing and telephone-signaling support. Its programmable CMOS architecture integrates a one-channel SLIC/CODEC, ringing generator, battery-voltage generation, DTMF processing, and Caller ID generation. The 3.3 V or 5 V operating options are useful in dual-rail telecom platforms, while the 38-pin TSSOP package simplifies surface-mount assembly. Designers must account for approximately 41 mA operating current in the device power budget and carefully isolate the 90 VPK ring drive from sensitive logic. Because the part is obsolete, new DSL terminal development should validate a supported alternative rather than assume that the BT suffix can be substituted without a complete device-level review.
מומלץ
Line-Powered Fax and Data Terminal
The SI3210-BT is applicable to line-powered fax or data terminal hardware where a standard analog telephone interface and signaling functions are required. The integrated ringing and battery-voltage generation blocks can simplify the external line circuit, while DTMF decoding supports control signaling and Caller ID generation supports subscriber-information display. The documented 5 REN and 90 VPK ring capability should be reconciled with the telephone network's load requirements before deployment. PCB design should maintain appropriate separation between high-voltage ring paths and low-voltage signal traces, and production tests should cover hook-state, DTMF, and ring-cadence behavior. For equipment still in production, preserving the validated SI3210-BT configuration may be preferable to a redesign; for new programs, supported sourcing must be established first.
מומלץ
Embedded Voice Communication Controller
The SI3210-BT can be used in an embedded voice communication controller that needs to terminate one analog telephone line while managing call-control signaling. Its programmable CMOS SLIC/CODEC consolidates voice conversion and line functions, and the manufacturer family documentation identifies ringing generation, battery-voltage generation, DTMF generation and decoding, and Caller ID generation as integrated capabilities. A 3.3 V or 5 V system can use the device, subject to the 3.13 V to 5.25 V family limits and the approximately 41 mA operating-current comparison value. Software must configure the line and signaling behavior correctly for each market, and the hardware must tolerate the 90 VPK ring environment. Obsolete lifecycle status makes this primarily a continuity choice for validated embedded products.

הערות תכנון
Do not treat every SI3210 ordering suffix as automatically interchangeable. The verified sources establish the 38-pin surface-mount format and common SLIC family, but they do not provide a complete suffix-by-suffix electrical table. Before replacing SI3210-BT with SI3210-FT, SI3210-GT, or SI3210-KT, compare the package drawing, control-register behavior, operating-temperature limits, line impedance, ring configuration, and approved firmware. The obsolete status also requires an obsolescence and PCN review.
Treat the 90 VPK ring path as a high-voltage signal path even though the ringing generator is integrated. Maintain the required clearance and creepage between ring and battery connections, low-voltage supplies, digital interfaces, and sensitive analog nodes. Place external protection and filtering components close to the line-entry points, and verify that their pulse ratings exceed the applicable telephone-line transients. Copper, solder mask, and adjacent-part selection must be reviewed together rather than relying only on component spacing.
The verified comparison value of approximately 41 mA should be included in the supply design, but it must not be treated as the complete worst-case consumption without checking ring cadence, line state, and configuration. Provide local decoupling according to the manufacturer layout guidance, keep return-current paths short, and account for the power needed by external protection and line-network components. The device can operate from 3.3 V or 5 V, while the family comparison specifies 3.13 V to 5.25 V.
