Texas Instruments PCM6260Q1EVM-PDK

Overview

PCM6260Q1EVM-PDK from Texas Instruments is an evaluation module (EVM) designed to demonstrate the performance and configuration of the PCM6260Q1, a 6-channel, high-performance, automotive-grade audio analog-to-digital converter (ADC) with integrated boost converter. It supports differential/AC- or DC-coupled line/mic inputs, I²S/TDM digital audio output, and real-time diagnostics - enabling rapid validation of audio front-end designs for infotainment and ADAS microphones.

For engineers reviewing the PCM6260Q1EVM-PDK datasheet, PCM6260Q1EVM-PDK pinout, PCM6260Q1EVM-PDK application, or PCM6260Q1EVM-PDK equivalent, this EVM provides full hardware-software integration with PurePath Console 3, configurable I²C address, jumper-selectable input modes (10 VRMS differential, 5 VRMS single-ended), GPIO1 interrupt/MCLK routing, and AC-MB motherboard compatibility for USB/optical/external ASI audio sources.

Technical Context

The PCM6260Q1EVM-PDK consists of a daughterboard hosting the PCM6260Q1 ADC and an AC-MB motherboard providing power, digital audio interface, and control. The AC-MB supplies 1.8 V or 3.3 V IOVDD via jumper J3 and routes MCLK/BCLK/FSYNC/DIN/DOUT through header J7 for external ASI operation.

Input flexibility includes six channels with configurable biasing (MICBIAS voltage options: 5 V/7 V/9 V), jumper-based AC/DC coupling (e.g., J16/J17 for IN3 differential DC-coupling), and onboard electret microphone support with J27 shorted. Diagnostics are enabled via jumpers J32/J34 and SW1 fault injection.

FAQ

What is the primary function of the PCM6260Q1EVM-PDK?

The PCM6260Q1EVM-PDK is an evaluation module that demonstrates the operation and configuration of the PCM6260Q1 6-channel automotive audio ADC. It enables engineers to validate signal chain performance, test diagnostics features, configure input coupling modes, and integrate with host processors via I²S/TDM. The PCM6260Q1EVM-PDK includes both daughterboard and AC-MB motherboard for complete system-level evaluation.

Which audio interface formats does the PCM6260Q1EVM-PDK support?

The PCM6260Q1EVM-PDK supports I²S and TDM digital audio output formats, configurable via PurePath Console 3 GUI. Default operation uses TDM with 32-bit frame size and 48-kHz sampling, but users can switch to 2-channel I²S at 16-bit/48-kHz. Audio clocking is provided by the AC-MB motherboard via USB, optical, analog, or external ASI sources - all routed to the PCM6260Q1EVM-PDK through J7.

How do I configure differential DC-coupled inputs on the PCM6260Q1EVM-PDK?

To configure differential DC-coupled inputs on the PCM6260Q1EVM-PDK, install jumpers on the relevant channel's positive/negative input terminals (e.g., J9 and J10 for IN2, J16 and J17 for IN3) and optionally remove bias resistors (e.g., R34/R35 for IN3) per Table 2-1. MICBIAS must be disabled or disconnected, and J27 left open. This setup supports ±2 VRMS normal mode or ±10 VRMS high-swing mode, verified in the PCM6260Q1EVM-PDK User's Guide Section 2.2.1.

Can the PCM6260Q1EVM-PDK be used with an external master clock source?

Yes - the PCM6260Q1EVM-PDK supports external MCLK input via GPIO1 when configured as master. To enable this, remove resistor R21 and install R22 on the bottom side of the board, connecting GPIO1 to the MCLK pin on the AC-MB's external ASI header (J7). This configuration is required only when the PCM6260Q1 operates as audio serial bus master, and is documented in Section 2.2.4.2 of the PCM6260Q1EVM-PDK User's Guide.

What software tools are required to operate the PCM6260Q1EVM-PDK?

Operation requires Texas Instruments' PurePath Console 3 (PPC3) framework and the dedicated PCM6260Q1EVM-SW GUI plugin. PPC3 must be installed first from ti.com/tool/PUREPATHCONSOLE; then the PCM6260Q1EVM-SW is added via ti.com/tool/PCM6260Q1EVM. The GUI provides real-time control of audio configuration, diagnostics, audio serial bus settings, and register-level access - all validated for use with the PCM6260Q1EVM-PDK hardware.
