An optical cable (TOSLINK) is needed between your digital source and the development kit. The format used is
S/PDIF coming from the Philips/Sony standard. Many different digital sources can be used such as minidisc, CD
player or DAT.
The CD audio source must be selected on the “GUI” in order to put the CODEC in CD-mode and to start the CD-
related part of the board. The “mck” jumper [7] must be on the left side to receive the clock from the CD-source.

The Connector “R42” [20] has been implemented in order to connect a loudspeaker without the need of a special
plug. You can fix the wire from the loudspeaker directly into this connector.

The XE3000 Development kit is designed to allow easy evaluation of the XE3000 series of low power CODECs.
It contains an XE3006 CODEC, a Semtech microcontroller XE8805 [22] that controls the board functions such as
communication with a personal computer and digital audio interface. The digital audio interface allows you to listen
to music from a compact disc player with an optical output, directly through the XE3006 CODEC.
At start-up, or after a reset, all blocks in the CODEC are running. The LC05 sets the CODEC in loop-back mode if
the board is not connected to a personal computer. The preamplifier gain is set to the max value (20x).
The output of the kit can be listened to by means of a headphone with or without amplification (direct output from
the XE3006 CODEC). Use a headphone with a power control or the one supplied with the kit.

The features and functions of the XE3006 ultra low power CODEC are described in its data sheet.
