| 13 | Lochnagar is an evaluation and development board for Cirrus Logic |
| 14 | Smart CODEC and Amp devices. It allows the connection of most Cirrus |
| 15 | Logic devices on mini-cards, as well as allowing connection of various |
| 16 | application processor systems to provide a full evaluation platform. |
| 17 | Audio system topology, clocking and power can all be controlled through |
| 18 | the Lochnagar, allowing the device under test to be used in a variety of |
| 19 | possible use cases. |
