5.3. WM8523-EB Overview
The WM8523 evaluation board contains a pre-installed WM8523 for evaluation and preliminary software develop-
ment with the CP2114 evaluation board. Refer to Figure 8 for the locations of the various I/O connectors on the
WM8523-EB.
5.3.1. Daughter Card Connector (J1)
The J1 connector is used to connect to a CP2114 evaluation board (CP2114-EB). The WM8253-EB must be
plugged into a CP2114 evaluation board to function properly.
5.3.2. Line Output Connector (J2)
The J2 connector is used to connect powered speakers to the WM8253 evaluation board.
5.3.3. Headphone Output Connector (J3)
The J3 connector is used to connect headphones to the WM8253 evaluation board.
5.3.4. I2S/I2C Signal Connectors (JP2-JP10)
Connectors JP2 through JP10 are provided to allow access to the I2S/I2C signals between the CP2114 and
WM8253. Placing a shorting block between pins 1 and 2 will connect the CP2114 to the WM8253. Placing a
shorting block between pins 2 and 3 will connect the corresponding WM8253 pin to ground. When monitoring the
I2S signals, connect the scope probe ground lead to the adjacent ground pin.
