| PT8915 USB Speaker Controller with Class-D Amp. DESCRIPTION The PT8915 is a cost-efficient single chip for USB speaker application. It integrated USB controller, 16 bit audio DAC, line input and high power, high efficient Class-D audio amplifier in one chip. Only few external components needed in application circuits makes it suite for the USB powered speaker system. The I/O interface is totally follow the USB audio class specification. No special driver software needs to install on user's computer and support most popular Operating System in the recent market. The PT8915 is a truly plug and play USB audio device. The embedded GPIO pins provide the mute and volume adjustment functions whatever the USB port is connected or not, Via the IC pins. Vendor can store vendor specified VID, PID, language ID and product string information in external EEPROM. FEATURES * Compliant with USB2.0 full speed specification. * Compliant with USB Audio class specification. * Compliant with USB HID class specification for volume and mute remote control. * Supply voltage: 4.5~5.5V * Build-in class-D audio amplifier with 2Watt output power for each channel. * Built-in PLL(48MHz for USB) * Built-in USB/LINE IN function for selecting PC or external signal. * Key pad control in USB and Line IN function for mute, volume up and volume down. * I2C interface for optional external EEPROM to store vendor specified VID, PID, language ID and product string information. * Packages: 28 pins SOP APPLICATION * USB Speaker BLOCK DIAGRAM Tel: 886-66296288Fax: 886-29174598 http://www.princeton.com.tw2F, 233-1, Baociao Road, Sindian, Taipei 23145, Taiwan PT8915 APPLICATION CIRCUITS V1.2 2 December 2009 PT8915 ORDER INFORMATION Valid Part Number PT8915-S Package Type 28 Pins, SOP, 300mil Top Code PT8915-S PIN CONFIGURATION V1.2 3 December 2009 PT8915 PIN DESCRIPTION Pin Name VDD1 USBDP USBDM Vreg USB/LINE GND2 Vref VDD2 DACOR VOLINR INR INL VOLINL DACOL MUTE VOLUP/DN OUTLP GNDL VDDL OUTLN OUTRN VDDR GNDR OUTRP IICSDA IICSCL OSCO OSCI I/O Power I I Power I power Power Power O I I I I O I I O Power Power O O Power Power O O O O I Description USB 5V power USB data plus USB data minus Regulator 3.3V power USB/Line-In mode selector, issue remote wake up signal for PC/Notebook system suspend.
