5.4.6. PCM1774 Supply Voltage Connector (JP9)
This header (JP9) is included on the evaluation board to provide several power options for the PCM1774. The
following describes the function of each pin:
Shorting pins 1,2: Connects the regulator output on the PCM1774-EB to the supply of the PCM1774.
Shorting pins 2,3: Connects the CP2114 VDD (CP2114 pin 7) to the supply of the PCM1774.
5.4.7. External Capacitor Connectors (JP15, JP16)
The JP15 and JP16 connectors allow external capacitors to be connected to the HP/LINE OUT connector. For best
low frequency response (35 Hz cutoff), remove the jumpers on JP15 and JP16. For maximum power output (45 Hz
cutoff), place the jumpers on JP15 and JP16.
