CP2114-EK
5.2. CS42L55-EB Overview
The CS42L55 evaluation board contains a pre-installed CS42L55 for evaluation and preliminary software develop-
ment with the CP2114 evaluation board. Refer to Figure 7 for the locations of the various I/O connectors on the
CS42L55-EB.
5.2.1. Daughter Card Connector (P1)
The P1 connector is used to connect to a CP2114 evaluation board (CP2114-EB). The CS42L55-EB must be
plugged into a CP2114 evaluation board to function properly.
5.2.2. Analog Input Connector (P2)
The P2 connector is used to connect an input device to the CS42L55 evaluation board.
5.2.3. Line Output Connector (P3)
The P3 connector is used to connect powered speakers to the CS42L55 evaluation board.
5.2.4. Headphone Output Connector (P4)
The P4 connector is used to connect headphones to the CS42L55 evaluation board.
5.2.5. I2S/I2C Signal Connectors (JP1-JP5, JP9, JP10)
Connectors JP1 through JP7, JP9, and JP10 are provided to allow access to the I2S/I2C signals between the
CP2114 and CS42L55. Placing a shorting block between pins 1 and 2 will connect the CP2114 to the CS42L55.
Placing a shorting block between pins 2 and 3 will connect the corresponding CS42L55 pin to ground. When
monitoring the I2S signals, connect the scope probe ground lead to the adjacent ground pin.
