TLV320AIC1103GQER

Codecs Overview

The TLV320AIC1103GQER is a PCM codec designed for voice-band communications systems, operating on a single 2.7-V to 3.3-V supply. It features two differential microphone inputs and one differential plus one single-ended earphone output. The device supports 15-bit linear data or 8-bit companded (µ-law/A-law) formats via an I²C interface. Internal clocks are generated from a 2.048-MHz master clock input using a phase-locked loop. It includes programmable gain amplifiers, DTMF generation, and a PDM buzzer output. The component is housed in an 80-pin MicroStar Junior BGA package.

Codecs Feature Summary

• Integrated transmit encoding and receive decoding with analog/digital conversion capabilities
• Dual differential microphone inputs with switchable low-noise amplifier stages
• Built-in dual-tone multifrequency and single tone generator with pulse density modulation output
• Configurable power-up modes allowing operation without a microcontroller

Codecs Applications

• Digital handsets
• Digital headsets
• Cordless phones
• Digital PABX systems
• Digital voice recording devices

Codecs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. Confirm that the GQE suffix corresponds to the 80-pin MicroStar Junior BGA package as specified in the datasheet. Ensure compatibility with the required I²C bus voltage levels and check for any obsolete status notifications from Texas Instruments before finalizing procurement plans.

Codecs Selection Notes

Select this component for applications requiring integrated voice-band processing with minimal external components. The device supports both linear and companded audio formats selectable via software. Consider the available power-up default mode if system initialization requires operation without an active host controller. Verify that the 2.048-MHz master clock requirement aligns with the system timing architecture.

Codecs Part Context

This part belongs to the TLV320AIC1103 series of PCM codecs manufactured by Texas Instruments. The GQE suffix specifically denotes the 80-pin MicroStar Junior Ball Grid Array package variant. The device is engineered for telecommunications and portable audio applications where space efficiency and low power consumption are critical design constraints.

Codecs Replacement Considerations

Consult the Texas Instruments product selection guide for direct pin-compatible alternatives within the same family. Verify functional equivalence regarding I²C register maps and electrical characteristics when substituting.
