provides the differential to LVDS clock multiplexer pin-out details.

D/A Converter Output SMA Connector (J12, J14)

J12 (channel A) and J14 (channel B) are standard through-hole SMA connectors used
to interface the DAC5672 D/A converter output with SMA cables.

Audio CODEC Converter (U5)

The Data Conversion HSMC contains three stereo jack and one mic jack connectors
which provide one stereo output, one stereo input, one amplified stereo headphone
output, and one microphone input. The stereo jacks are driven by a stereo audio
CODEC running at 8 to 96 kHz.

Table 2–16

lists the audio CODEC board reference

and manufacturing information.

Table 2–17

provides the TI TLV320AIC23 audio CODEC pin-out details.

I2S A/D converter-word clock signal. In audio master
mode, the AIC23B generates this framing signal and sends
it to the DSP. In audio slave mode, the signal is generated
by the DSP.

I2S D/A converter-word clock signal. In audio master
mode, the AIC23B generates this framing signal and sends
it to the DSP. In audio slave mode, the signal is generated
by the DSP.
