Product details
Overview
TLV320AIC1106PWRG4 from Texas Instruments is a single-chip PCM audio codec IC designed for voice-band telecommunication endpoints, performing A/D and D/A conversion, transmit/receive filtering, and volume control. It operates at 2.7–3.3 V, supports 13-bit linear or 8-bit µ-law companding, delivers 200 mW differential output into 8 Ω, and features 300 Hz–3.4 kHz passband with 70 dB crosstalk attenuation.
For engineers reviewing the TLV320AIC1106PWRG4 datasheet, TLV320AIC1106PWRG4 pinout, TLV320AIC1106PWRG4 application, or TLV320AIC1106PWRG4 equivalent, this page provides verified functional identity, validated 20-pin TSSOP package mapping, confirmed dual-mode (linear/µ-law) PCM interface timing, real-world earphone/microphone drive capability, and two manufacturer-validated alternative codecs for voice-band system design.
Technical Context
The TLV320AIC1106PWRG4 integrates a third-order sigma-delta analog modulator for transmit path and a second-order digital modulator/filter for receive path, both synchronized to a 2.048 MHz master clock. Its PLL locks to MCLK to generate internal clocks for digital filters meeting CCITT G.714 requirements.
It implements differential microphone input with externally settable gain (23.5 dB typical), programmable mute functions for MIC and EAR channels, and linear-mode volume control via three LSBs of PCMI data (−18 dB to +3 dB in 3-dB steps). The device achieves −80 dBm0p transmit idle noise and −90 dBm0 receive noise in µ-law mode.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MICMUTE (1) | Microphone mute control input | Active-high signal providing 80-dB attenuation of MICIN path; enables hardware-based voice activation gating. |
| RESET (2) | Active-low asynchronous reset | Must be asserted with MCLK active for reliable power-up initialization; ensures known state before PCM data transfer. |
| VSS (3) | Analog reference ground | Return for internal band-gap reference; must be isolated from digital ground to minimize noise coupling. |
| EARVSS (4, 8) | Earphone amplifier analog ground | Dual ground pins for EAROUT+ and EAROUT− outputs; critical for maintaining differential output symmetry and PSRR. |
| EAROUT+ (5) | Earphone amplifier positive output | Differential output terminal; drives one side of 8–32 Ω load; click/pop suppression enabled by internal timing. |
| EARVDD (6) | Earphone analog supply | Separate 2.7–3.3 V rail for earphone amp; decoupling required to prevent supply-induced distortion. |
| EAROUT− (7) | Earphone amplifier negative output | Complementary differential output; used with EAROUT+ for balanced drive and improved EMI performance. |

| PCMO (17) | PCM transmit data output | Serial PCM output carrying digitized microphone data; high-impedance during power-down for bus sharing. |
| PCMSYNC (18) | PCM frame synchronization | 8-kHz frame sync input derived from MCLK; acts as host interrupt trigger and defines PCM word boundaries. |
| MCLK (19) | Master clock input | 2.048-MHz CMOS-level clock; source for internal PLL and all timing generation; jitter ≤37% tolerated. |
| EARMUTE (20) | Earphone mute control input | Active-high signal attenuating EAROUT path by 80 dB; supports call-waiting and hands-free mute functions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PCM codec applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV320AIC101IDBT | Single-supply 2.7–3.6 V operation; fixed 8-bit µ-law only; no LINSEL pin; lower 160 mW earphone output. | Targeted at cost-sensitive µ-law-only PABX terminals; lacks linear mode flexibility and 200 mW drive capability. | Select when µ-law compatibility is mandatory and 13-bit resolution or high-output drive is unnecessary. |
| TLV320AIC23BIPW | I²S/MSB-justified interface instead of PCM; stereo support; 16–24-bit resolution; higher 3.3-V supply requirement. | Designed for multimedia audio (e.g., MP3 players), not telephony; requires different controller interface and layout. | Select for stereo consumer audio where PCM frame sync and µ-law compliance are irrelevant. |
Compared with TLV320AIC1106PWRG4, TLV320AIC101IDBT offers reduced feature set and output power for simpler µ-law systems, while TLV320AIC23BIPW shifts to stereo I²S architecture-neither provides pin-compatible or drop-in replacement capability, but both serve adjacent voice/audio segments with distinct interface and resolution trade-offs.

FAQ
What is the primary function of the TLV320AIC1106PWRG4 in a voice communication system?
The TLV320AIC1106PWRG4 serves as a complete PCM audio codec IC, performing analog-to-digital conversion of microphone signals and digital-to-analog conversion of received PCM data, along with transmit/receive filtering, volume control, and hardware mute functions. In a voice system, TLV320AIC1106PWRG4 bridges the analog audio world (microphone, earpiece) with the digital baseband processor using standardized 8-kHz PCM framing.
Does the TLV320AIC1106PWRG4 support both linear and µ-law PCM formats, and how is mode selection implemented?
Yes, the TLV320AIC1106PWRG4 supports both 13-bit linear and 8-bit µ-law companded PCM modes. Mode selection is controlled by the LINSEL input pin: a logic low selects linear mode (enabling 3-bit volume control via RXVOL bits), while a logic high selects µ-law mode (fixed 0 dB volume). This hardware-selectable dual-mode capability allows TLV320AIC1106PWRG4 to interoperate with diverse telephony infrastructure without firmware changes.
What are the power supply requirements and consumption characteristics of the TLV320AIC1106PWRG4?
The TLV320AIC1106PWRG4 requires two independent 2.7–3.3 V supplies: EARVDD for the earphone amplifier and DVDD for digital circuitry. Typical operating supply current is 7 mA, dropping to 30 µA in power-down mode when MCLK is absent. The device also specifies 0.03 mW typical power dissipation in power-down, making TLV320AIC1106PWRG4 suitable for battery-powered voice terminals with strict standby power budgets.
How does the TLV320AIC1106PWRG4 handle microphone input gain and noise performance?
The TLV320AIC1106PWRG4 features a differential microphone input with an externally configurable preamplifier (MIC Amp 1) whose gain is set by resistors R2 and R3. With recommended values (R2 = 34 kΩ, R3 = 510 kΩ), it achieves 23.5 dB gain and 2.9 µVrms psophometric noise. TLV320AIC1106PWRG4 also includes MICMUTE for 80-dB hardware attenuation, and its input offset voltage is tightly controlled (±5 mV) to preserve low-level signal fidelity.
What is the significance of the 2.048-MHz master clock and 8-kHz PCMSYNC in the TLV320AIC1106PWRG4 timing architecture?
The 2.048-MHz MCLK feeds an internal PLL that generates all required clocks for sigma-delta modulation, digital filtering, and PCM interface timing. PCMSYNC is derived from MCLK (256:1 division) to produce an exact 8-kHz frame sync signal, aligning with standard telephony sampling rates. This precise timing ensures TLV320AIC1106PWRG4 maintains bit-accurate PCM data alignment with host processors and PSTN gateways without requiring additional clock synthesis circuitry.
