The USB protocol controller works with no software code, but the USB descriptors can be modified in some areas (e.g., vendor ID/product ID). The PCM2900/2902 employs SpAct™ architecture, TI's unique system that recovers the audio clock from USB packet data. On-chip analog PLLs with SpAct architecture enable playback and record with low clock jitter and with independent playback and record sampling rates. (1) The descriptor can be modified by changing a mask. 1 2 3 4 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

The control end-point is used to control all functions of the PCM2900/2902 by the standard USB request and USB audio class specific request from the host. The isochronous-out audio data stream end-point is an audio sink end-point, which receives the PCM audio data. The isochronous-out audio data stream end-point accepts the adaptive transfer mode. The isochronous-in audio data stream end-point is an audio source end-point, which transmits the PCM audio data. The isochronous-in audio data stream end-point uses asynchronous transfer mode. The HID end-point is an interrupt-in end-point. HID end-point reports HID0, HID1, and HID2 pin status every 32 ms. The human interface device (HID) pins are defined as consumer control devices. The HID function is designed as an independent end-point from both isochronous-in and -out end-points. This means that the result of affection for the HID operation depends on the host software. Typically, the HID function is affected for the primary audio-out device. Clock and Reset The PCM2900/2902 requires a 12-MHz (±500 ppm) clock for the USB and audio function, which can be generated by a built-in crystal oscillator with a 12-MHz crystal resonator. The 12-MHz crystal resonator must be connected to XTI (pin 21) and XTO (pin 20) with one high (1-MΩ) resistor and two small capacitors, the capacitance of which depends on the load capacitance of the crystal resonator. The external clock can be supplied from XTI (pin 21). If the external clock is supplied, XTO (pin 20) must be left open. Because of no clock-disabling signal, it is not recommended to use the external clock supply. SSPND (pin 28) is unable to use clock disabling. The PCM2900/2902 has an internal power-on reset circuit, which works automatically when VBUS (pin 3) exceeds 2.5 V typical (2.7 V–2.2 V), and about 700 µs is required until internal reset release. Digital Audio Interface (PCM2902) The PCM2902 employs both S/PDIF input and output. Isochronous-out data from the host is encoded to the S/PDIF output and the DAC analog output. Input data is selected as either S/PDIF or ADC analog input. When the device detects an S/PDIF input and successfully locks the received data, the isochronous-in transfer data source is automatically selected from S/PDIF itself; otherwise, the data source is selected to ADC analog input. Supported Input Data (PCM2902) The following data formats are accepted by the S/PDIF input and output. All other data formats are unable to use S/PDIF. • 48-kHz 16-bit stereo • 44.1-kHz 16-bit stereo • 32-kHz 16-bit stereo Mismatch between input data format and host command may cause unexpected results except in the following conditions. • Record monaural format from stereo data input at the same data rate • Record 8-bit format from 16-bit data input at the same data rate A combination between the above conditions is not accepted. For the playback, all possible data rate source is converted to 16-bit stereo format at the same source data rate.

All other bits are fixed as 0s except for the sample frequency, which is set automatically according to the data received through the USB. Copyright Management (PCM2902) Isochronous-in data is affected by the serial copy management system (SCMS). Where receiving digital audio data that is indicated as original data in the control bit, input digital audio data transfers to the host. If the data is indicated as first generation or higher, transferred data is selected to analog input. Digital audio data output is always encoded as original with SCMS control. The implementation of this feature is an option for the customer. Note that it is the user's responsibility whether they implement this feature in their product or not. INTERFACE SEQUENCE Power On, Attach, and Playback Sequence The PCM2900/2902 is ready for setup when the reset sequence has finished and the USB bus is attached. After connection has been established by setup, the PCM2900/2902 is ready to accept USB audio data. While waiting, the audio data (idle state) and analog output are set to bipolar zero (BPZ). When receiving the audio data, the PCM2900/2902 stores the first audio packet, which contained 1-ms audio data, into the internal storage buffer. The PCM2900/2902 starts playing the audio data when detecting the following start of frame (SOF) packet. 5 V (Typ) 2.5 V (Typ) VBUS (Pin 3) 0V Bus Reset Bus Idle D+/D– Set Configuration 1 Audio Data st 2 nd Audio Data SOF SOF SOF SSPND VOUTL VOUTR BPZ 700 ms Internal Reset Device Setup Ready for Setup 1 ms Ready for Playback T0055-02 Figure 32.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
