CDB6271-2 ('Lochnagar 2') Development Platform

The CDB6271-2 (‘Lochnagar 2’) can stream up to 16 channels of USB audio from the PC. It has software-controlled signal routing options, a wide range of analogue and digital audio input and outputs, and a built-in current monitor feature that allows the power consumption of Cirrus Logic devices to be measured without any external equipment. It is the same form factor as the original 6271-EV1 (‘Lochnagar’) board and is compatible with the same daughtercards.

The CDB6271-2 (‘Lochnagar 2’) is designed to operate with the WISCE™ Development Tools Suite, which is a prerequisite for use of the board. The CDB6271-2 (‘Lochnagar 2’) support can be added to WISCE by installing the Device Pack, which also installs the necessary audio and communication drivers.

Key Benefits:

• Single USB cable provides power and communications to the board;
• Interchangeable daughtercards to support a range of Cirrus Logic devices;
• Software-controlled signal routing to support many different use cases and configurations;
• Graphical WISCE plugin to simplify control and configuration;
• Integrated board firmware update utility for feature set enhancements;
• 16-channel USB audio class 2.0 streaming;
• 3.5 mm analog jacks with integrated DAC/ADC;
• Current monitor functionality on up to eight supply rails for power measurements;
• Support for SPI, I²C, JTAG and UART protocols.
