Cyclone II FPGA Starter Development Board

October 2006

Development Board Components

This device features microphone-in, line-in, and line-out ports, with a
sample rate adjustable from 8 kHz to 96 kHz. A serial I2C bus interface
connected to FPGA pins controls the WM8731 CODEC.

f

For information about the WM8731 CODEC, refer to the

BoardDesignFiles\Datasheet

folder in the kit installation directory or to

the manufacturer's web site.
