Cirrus Logic Lochnagar Audio Development Board
|
||
|
|
|
||
|
|
Lochnagar is an evaluation and development board for Cirrus Logic
|
||
|
|
Smart CODEC and Amp devices. It allows the connection of most Cirrus
|
||
|
|
Logic devices on mini-cards, as well as allowing connection of
|
||
|
|
various application processor systems to provide a full evaluation
|
||
|
|
platform. Audio system topology, clocking and power can all be
|
||
|
|
controlled through the Lochnagar, allowing the device under test
|
||
|
|
to be used in a variety of possible use cases.
