description: |
|
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.
