描述 Description

The OTi-6888 is a USB host with MP3 interface controller. User can stores the mp3 file in the USB device (USB flash disk , USB card reader and USB portable hard Disk). When the USB device plug in USB port and push the play key. The OTi6888 will read the mp3 file from USB device, and send the data to MP3 decoder and DAC. The user can hear MP3 song where stores in USB device.

The USB interfaces are for full speed operation (12Mb/s). It conforms to USB Specification, Version 1.1. The USB transceiver is embedded in this controller. With stable slew-rate control, the controller reduces EMI.

The OTi-6888 has a Phase Lock Loop (PLL) embedded. The PLL provides all clocks needed in this controller. It needs an externally provided clock operating in 14.318MHz.

The controller has two LED control pin.
