3.1.1 Audio Inputs

3.1.1.1 Analog Line-level Inputs

• Connector Type: RCA Female

• Absolute Maximum Signal Level: +6.5V

• Absolute Minimum Signal Level: GND - 0.7V

• Full Scale Amplitude: 2V

RMS

• Reference Designators: J4, J6-J10, J12, J26-J30, or AIN1A - AIN6B

3.1.1.2 Digital Optical Input

Note: Digital Optical Input is PCM only as there is no multi-channel decoder present on CDB48500-USB.

• Connector Type: Fiber Optic RX for Digital Audio, JIS F05 (JIS C5974-1993 F05)

• Reference Designator: J2, or SPDIF_RXP

3.1.1.3 Digital Coaxial Input

Note: Digital Coaxial Input is PCM only as there is no multi-channel decoder present on CDB48500-USB.

• Connector Type: RCA Female

• Maximum Signal Level: +3.3V

• Minimum Signal Level: GND - 0.7V

• Reference Designator: J31, or SPDIF_RXN

3.1.1.4 Microphone Input

• Absolute Maximum Signal Level: +5V

• Absolute Minimum Signal Level: GND - 0.7V

• Full Scale Amplitude: 7mVp-p

• Reference Designator: J5

The microphone preamplifier shares the AIN1_5 ADC with the AIN3_A RCA jack. Only one analog source can

be sampled at any given time. When the microphone input is selected, the AIN3_A audio jack is ignored. The

default configuration enables the AIN3_A audio jack.
