SI3210-GT - Programmable CMOS SLIC/CODEC | Skyworks Solutions
Teilenummer: SI3210-GT ✗ AbgekündigtSI3210-GT Übersicht
A SLIC is the line-facing portion of a telephone interface, while a codec converts between analog voice signals and digital PCM data. The SI3210-GT combines these functions with ringing and battery-voltage generation to reduce the number of external components required in terminal adapters, cable telephony products and related short-loop equipment. In this product hierarchy, it is an integrated SLIC and codec within the broader category of telecom interface ICs.
Programmable operation allows the device to be configured for different line conditions and application requirements. This is particularly useful in products that must accommodate variations in loop length, subscriber-line loading, ringing behavior or voice-path implementation. The integrated battery generator supports the line-powering requirements associated with analog telephone equipment, while the codec provides the voice interface to the surrounding digital communications system.
The SI3210-GT is particularly relevant to compact telephone line-card and terminal-adapter designs. Its 38-pin TSSOP package provides a practical surface-mount format for equipment where a larger quad flat package would be unnecessary. Because the device includes SLIC, codec and battery-generation circuitry, board designers can evaluate whether separate line-interface and voice-processing components can be consolidated, provided the complete electrical, timing and firmware requirements of the target design remain satisfied.
Typical applications include cable telephony terminal adapters, short-loop line interfaces, analog telephone adapters and wireless local-loop equipment. The device is also associated with legacy telecom-interface designs, so firmware, line-state supervision and analog compliance testing are important considerations when integrating it into new equipment.
Design work should follow the manufacturer datasheet for power sequencing, external line-network components, codec clocking, digital interface connections, filtering and layout. The 3.13 V to 5.25 V supply range does not remove the need to verify every minimum and maximum operating condition, particularly during ringing, hook-state transitions and off-hook load changes.
This product page combines the documented SLIC, codec, battery-generation and package characteristics with application guidance, verified source links, comparison details and engineering-focused design notes. It is intended to help engineers identify the correct legacy telecom-interface part and evaluate replacement decisions without overlooking software, line-network or package-compatibility requirements.

Cable Telephony Terminal Adapter
The SI3210-GT fits a cable telephony terminal adapter because it integrates a programmable subscriber line interface, voice codec and battery-voltage generation in one low-voltage CMOS device. Its documented 3.13 V to 5.25 V supply range is appropriate for a compact low-voltage line interface, while the 38-pin TSSOP package simplifies surface-mount assembly. Designers should use the manufacturer line-network circuit to select external protection, filtering and hook-state components, and should verify behavior across short-loop lengths, off-hook loads and ringing transitions before production release.
Empfohlen
Short-Loop Analog Telephone Adapter
For a short-loop analog telephone adapter, the SI3210-GT combines the line-facing SLIC, analog voice codec and battery-voltage generation required for a subscriber-line connection. Programmable operation is valuable when the adapter must support different loop, loading or ringing configurations without redesigning the hardware. The 3.13 V to 5.25 V operating range supports low-voltage design, while the integrated architecture can reduce board partitioning. Final approval still depends on line-network compliance, supervision behavior and the manufacturer application circuit.
Empfohlen
Wireless Local-Loop Terminal
The SI3210-GT is suitable for the analog line-facing section of a wireless local-loop terminal because it consolidates the SLIC, codec and battery generator into a programmable CMOS device. The manufacturer identifies wireless local-loop equipment among the target applications. Its 38-pin TSSOP format supports compact carrier-board construction, and its 3.13 V to 5.25 V supply range aligns with low-voltage equipment. Engineers should validate ringing energy, line impedance, codec clocking and power-consumption behavior under the complete radio and baseband system operating profile.
Empfohlen
Legacy Voice Line Card
A legacy voice line card can use the SI3210-GT where each channel requires a programmable SLIC, codec and battery-generation function in a single device. Integrating these blocks reduces the number of separate line-interface components and centralizes configuration within one programmable architecture. The documented 3.13 V to 5.25 V supply range and 38-pin TSSOP package are compatible with established multi-channel line-card construction practices. Production use requires attention to legacy device availability, lifecycle risk, firmware support and a complete channel-level functional test.
Empfohlen
Voice over Packet Adapter
The SI3210-GT can provide the analog subscriber-line and voice-codec boundary in a voice-over-packet adapter. Its SLIC handles the telephone line while the codec performs analog voice conversion, and programmable operation supports adaptation to different subscriber conditions. The integration of battery-voltage generation also supports the line-powering function normally required by analog endpoints. Because packet timing, echo cancellation and digital transport remain functions of the surrounding system, these functions must be tested at the complete adapter level rather than inferred from the SI3210-GT alone.
Empfohlen
Telephone Line Test Equipment
The SI3210-GT is applicable to telephone line test equipment that needs to emulate or analyze a programmable short-loop subscriber interface. Integrating the SLIC, codec and battery generator allows a tester to exercise both line and voice functions from one device. Its low-voltage CMOS implementation and 3.13 V to 5.25 V supply range are useful for compact instrument electronics, while the 38-pin TSSOP package simplifies board layout. Test limits, battery current, ringing voltage and loop coverage must be established from the manufacturer electrical specifications and application circuitry.

Wichtigste Unterscheidungsmerkmale

- Established 38-pin TSSOP package (vs. SI3210-FT)
- Programmable low-voltage CMOS implementation (vs. SI3210-KT)
Designhinweise
Design the SI3210-GT supply network for both normal off-hook load and line-ringing transients. The documented operating range is 3.13 V to 5.25 V, but the integrated battery generator and SLIC can create dynamic demands that should be checked against the manufacturer power-consumption and recommended circuit diagrams. Place supply bypassing close to the relevant device pins, maintain the recommended capacitor values and voltage ratings, and include test points for startup, hook transitions and full-load conditions.
Follow the manufacturer application and land-pattern guidance when assigning the 38-pin TSSOP footprint. Keep the line-side protection and filtering network physically close to the relevant SLIC and battery-generator connections, while separating sensitive analog voice routing from digital clock and data traces where practical. Use a continuous ground reference, minimize loop area around line-network components, and inspect the assembled board for unintended antenna structures that could couple ringing activity into the voice path.
Do not treat a shared package name as sufficient proof that a suffix can be substituted without qualification. SI3210-KT and SI3210-FT share the documented 38-pin TSSOP format, but operating-temperature grade, lifecycle constraints and electrical limits must still be checked for the exact ordering suffix. Also validate hook-state supervision, codec configuration, ringing behavior and battery current at the subsystem level, because package compatibility alone does not establish functional equivalence.
Compliance-Informationen
RoHS compliance is identified in the published SI3210 family comparison. No explicit REACH, lead-free, halogen-free, conflict-minerals or automotive qualification statement was established for the exact order code.
