5.4. PCM1774-EB Overview
The PCM1774 evaluation board includes contains a pre-installed a PCM1774 for evaluation and preliminary soft-
ware development with the CP2114 evaluation board. Refer to Figure 9 for the locations of the various I/O connec-
tors on the PCM1774-EB.
5.4.1. Daughter Card Connector (J1)
The J1 connector is used to connect to a CP2114 evaluation board (CP2114-EB). The PCM1774-EB must be
plugged into a CP2114 evaluation board to function properly.
5.4.2. Headphone/Line Output Connector (J2)
The J2 connector is used to connect headphones or powered speakers to the PCM1774 evaluation board.
5.4.3. Analog Input Connector (J3)
The J3 connector is used to connect an input device to the PCM1774 evaluation board.
5.4.4. I2S/I2C Signal Connectors (JP1–JP7)
Connectors JP1 through JP7 are provided to allow access to the I2S/I2C signals between the CP2114 and
PCM1774. Placing a shorting block between pins 1 and 2 will connect the CP2114 to the PCM1774. Placing a
shorting block between pins 2 and 3 will connect the corresponding PCM1774 pin to ground. When monitoring the
I2S signals, connect the scope probe ground lead to the adjacent ground pin.
5.4.5. Voltage Regulator Connector (JP8)
The JP8 connector is used to connect the VBUS signal being supplied to the CP2114 to the input of the voltage
regulator on the PCM1774 evaluation board. Installing this jumper connects the VBUS signal to the regulator
output. If another voltage supply is used, JP8 should be removed and the supply should be connected to pin 2 of
the header.
