  • Page 19 Spectrum Digital, Inc 2.3 AIC33 Interface The EVM uses a Texas Instruments TLV320AIC33 stereo codec for input and output of audio signals. The codec samples analog signals on the microphone or line inputs and converts them into digital data so it can be processed by the DSP. When the DSP is finished with the data it uses the codec to convert the samples back into analog signals on the line output so the user can hear the output.
  • Page 20 Spectrum Digital, Inc 2.4 Ethernet Interface The C6424 integrates an ethernet MAC on chip. The EVM supports RMII and MII protocols. The mode of operation is switch selectable via SW3. This interface is routed to the PHY via CBT switches. The EVM uses an Micrel KS8001L PHY. The 10/100 Mbit interface is isolated and brought out to a RJ-45 standard ethernet connector, P3.
  • Page 21 Spectrum Digital, Inc 2.5.1 I/O Expanders The C6424 EVM uses four I C expanders to handle various bit I/O functions. Each of these is an 8 bit I/O expander, a PCF8574A. At Power Up Reset the expanders are initialized to 0xFF, all ones. The functions for each of the I/O expanders are shown in the tables below.

  • Page 23 This eeprom is also used to store the ethernet MAC address and the board’s revision. The MAC address is also labeled on the board. Care should be taken not to erase these items when user information is stored in the eeprom. Spectrum Digital uses addresses 0x7F00 to 0x7FFF for manufacturing information. This information is shown in the table below.
  • Page 24 Spectrum Digital, Inc 2.7 Daughter Card Interfaces The EVM provides expansion connectors that can be used to accept plug-in daughter cards. The daughter card allows users to build on their EVM platform to extend its capabilities and provide customer and application specific I/O. The expansion connectors are for all major interfaces including memory, peripherals, and video expansion.
