PCM3060PW - 24-Bit Stereo Audio Codec | Texas Instruments
料号： PCM3060PW ✓ 量产中PCM3060PW 概述
An audio codec converts between analog audio and digital audio data. The PCM3060 integrates both conversion functions, control registers, digital attenuation, soft mute, de-emphasis, and serial host communication on one device. Its interface supports 3-wire SPI-compatible or 2-wire I²C-compatible control, while its audio interface handles the digital conversion data. This integrated architecture suits sound-processing equipment requiring stereo capture and playback without separate ADC and DAC packages.
The codec supports 16/24-bit digital audio words at sampling rates from 16 kHz through 96 kHz. Differential analog outputs help reduce common-mode noise and support balanced output routing, while the two single-ended ADC inputs simplify source capture. Programmable digital attenuation, soft mute, and de-emphasis provide useful control functions for consumer audio, television, set-top-box, and audiovisual equipment.
The PCM3060 is fabricated using an advanced CMOS process and integrates delta-sigma conversion, digital filtering, and interface control into a 28-pin TSSOP package. This mixed-signal design supports 24-bit resolution while keeping the external component count lower than a discrete converter solution. The control interface provides access to operating functions from a host processor.
Typical uses include DVD-RW equipment, digital televisions, set-top boxes, and other audiovisual systems. The same architecture also fits industrial sound modules, stereo recording interfaces, digital mixing equipment, and playback products requiring both microphone-line input capability and line-level differential output.
PCB implementation should preserve short analog traces, provide a quiet analog ground connection, and place input and output bypass capacitors close to their associated pins. The digital interface and analog signal paths should be routed to limit coupling between switching signals and sensitive conversion circuitry. Confirm the pin-description table in the manufacturer datasheet before assigning every trace and decoupling connection.
This product page combines the manufacturer’s codec specifications, package information, application guidance, pricing workflow, and verified drop-in substitution analysis. It also provides practical comparison points and design notes intended to accelerate component selection, PCB implementation, and second-source qualification for stereo audio designs.

典型应用
PCM3060PW 适用于 6 应用s: Digital Television Audio Processing, Set-Top-Box Audio Front End, DVD-RW Audio Conversion, Stereo Recording Interface, Industrial Sound Monitoring Module, Digital Playback Equipment.
Digital Television Audio Processing
The Texas Instruments PCM3060PW suits digital television audio paths that require both stereo capture and playback around a host processor. Its 24-bit ADC and DAC operate from 16 kHz to 96 kHz, while single-ended inputs and differential outputs support conventional television analog audio routing. The 3-wire SPI-compatible or 2-wire I²C-compatible control interface allows firmware access to digital attenuation, soft mute, and de-emphasis. Place bypass capacitors near the supply and analog pins, keep the clock and data traces short, and maintain a quiet analog return path to preserve signal quality.
推荐
Set-Top-Box Audio Front End
PCM3060PW provides a compact mixed-signal front end for set-top boxes that must accept stereo analog sources and generate differential audio outputs. Its integrated 24-bit ADC, 24-bit DAC, programmable attenuation, soft mute, and de-emphasis reduce the number of separate converter components. The supported 16–96 kHz range supports common media playback and source-conversion requirements, while SPI-compatible or I²C-compatible control supports host-managed register configuration. Validate input levels, output loading, clock generation, and ground separation against the manufacturer datasheet during schematic review.
推荐
DVD-RW Audio Conversion
The PCM3060PW is appropriate for DVD-RW and adjacent audiovisual equipment where stereo analog input, digital processing, and analog playback are required in one IC. Its stereo 24-bit ADC uses a 64-times delta-sigma modulator, and its DAC supports 64- or 128-times modulation, matching high-resolution audio conversion needs. The two single-ended inputs simplify source capture, while differential outputs can improve rejection of common-mode interference. During layout, separate codec clock routing from analog traces and use the pin-description table to place input and output capacitors correctly.
推荐
Stereo Recording Interface
PCM3060PW can form the core of a compact stereo recording interface that accepts two single-ended analog sources and returns differential stereo outputs. The 24-bit ADC and DAC path supports 16–96 kHz sampling, enabling a single codec architecture to cover multiple audio operating rates. Digital attenuation, soft mute, and de-emphasis are controlled through the programmable serial interface, allowing a host processor to manage gain-related functions. Use short, shielded analog routing, solid ground-plane design, and defined return paths to prevent digital coupling from raising the noise floor.
推荐
Industrial Sound Monitoring Module
The PCM3060PW fits industrial monitoring equipment that captures one or two analog channels, processes them digitally, and produces a stereo analog playback or test signal. Its integrated 24-bit conversion paths support 16–96 kHz operation, while the serial control interface simplifies configuration from an embedded controller. The operating range of -25 C to +85 C supports many indoor industrial environments, although the complete system still requires its own thermal and environmental qualification. Confirm analog input ranges, output loading, and clock jitter requirements during circuit design.
推荐
Digital Playback Equipment
PCM3060PW supports digital playback products requiring a high-resolution stereo DAC with integrated analog input capability for monitoring or source capture. Differential outputs can drive a downstream balanced or bridged analog stage, and programmable attenuation, soft mute, and de-emphasis simplify host-controlled playback behavior. At 16/24-bit word length and sampling rates from 16 kHz to 96 kHz, the codec can follow changing media formats. Ensure the digital audio interface timing, analog output filters, power distribution, and grounding follow the datasheet implementation guidance.

选型指南
设计说明
Route the PCM3060PW analog inputs and outputs as short, direct traces on the top signal layer, with the analog ground system referenced directly to the codec ground pins. Keep digital clock, data, and control traces away from the input/output nodes. Place analog bypass capacitors adjacent to the relevant supply pins and follow the pin-description table in the manufacturer datasheet because exposed-pad or capacitor assignments cannot be inferred solely from the package outline.
Treat the digital audio interface as a clocked signal path: use continuous reference planes, minimize stubbing, and route the audio clock away from analog input and output traces. Confirm source, destination, and codec I/O levels before connecting a host processor or audio transport. The PCM3060PW supports 3-wire SPI-compatible and 2-wire I²C-compatible control, but the selected mode must be configured consistently in hardware and firmware.
Do not assume that every 28-pin stereo audio codec is interchangeable with PCM3060PW. Even when package dimensions match, analog pin assignments, clock requirements, control registers, and power sequencing can differ. Build a substitution checklist covering every numbered pin, power supply, clock source, sample-rate range, control protocol, and analog impedance before approving another manufacturer or a different codec family for a second-source build.
Keep switching regulators, processors, and high-current digital return paths away from the codec analog section. Use a deliberate ground partition or unified ground strategy based on the complete board return path, and provide local decoupling at each supply connection. If the PCM3060PW is positioned near a connector or display interface, control connector return currents so they do not flow through the analog input/output reference network.
