CDB6271-2 Datasheet

For example, recent codec minicards such as Moon CDB47L91-M-1 do not use the DBVDD1, DBVDD2, DBVDD3, AVDD_1V8 rails, but instead derive all 1.8V rails from the single 1V8_CDC supply rail on Lochnagar and split the rails on the minicard .

In some scenarios, especially those using speakers, it may be necessary to plug a second power source into the Lochnagar 2 board. The onboard WM8310 PMIC will select the highest voltage from each of the three potential power supply inputs and use this to power the board's main SYSVDD bus. This is nominally 5V, but may be lower if a battery is used to supply the board.

2 Hardware Connections

USB connection to PC

Lochnagar 2 is powered and controlled via a single USB connection. This provides
• Power
• I2C/SPI communications to control device and board
• JTAG communications for DSP debug
• Multichannel USB streaming audio USB class 2
• USB serial port to communicate with Cirrus devices with UART interfaces

The board is provided with a Y-shaped USB cable, connecting a single USB B socket on Lochnagar 2 to two USB A ports on the computer Black plug for power + communications, Red for power only . Both USB connectors must be plugged in to allow for the power consumption of the board.

A Total Phase Aardvark connector is NOT required for Lochnagar 2 to operate, and neither does it require a separate power supply. All power and communications is provided to the board via this single USB link.

Power options

For most use cases, the provided USB cable is enough to power the entire board. In some scenarios, especially those using speakers, it may be necessary to plug a second power source into the Lochnagar 2 board. The onboard WM8310 PMIC will select the highest voltage from each of the three potential power supply inputs and use this to power the board's main SYSVDD bus. This is nominally 5V, but may be lower if a battery is used to supply the board.
