OTi-6888
USB 1.1 USB Host with MP3 Interface Controller
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.
FEATURES

USB 1.1 USB Host with MP3 Interface Controller
PIN DESCRIPTION
OTi-6888 has two different kinds of package, 48-pin and 64-pin. OTi-6888 with 48-pin
package provides fundamental USB host function, however, it can provide external ROM
functions if you choose 64-pin package.
Note: OTi-6888 with 48-pin package does not external ROM function.
Pin No.
