Component Interfaces

Audio Jacks (J19, J20, J21, J42)

The Data Conversion HSMC contains the following audio connectors:

■ J19—an audio connector for line-in

■ J20—an audio connector for line-out

■ J21—an audio connector for amplified line-out

■ J42—an audio connector for microphone

HSMC Connector (J1)

The Data Conversion HSMC connects to Altera FPGA starter and development

boards through a single HSMC connector (J6).

Table 2–18 lists the HSMC connector board reference and manufacturing information.

The HSMC connector is a modified version of the standard high-speed Samtec

connectors. To provide better integrity between host boards and daughter cards when

using high-speed transceivers, the standard high-speed Samtec connector is modified

by removing every third pin in bank 1.

1 CMOS utilization of the HSMC pins is assumed and no options for supporting other

differential signaling are provided with the board. The eight clock-data-recovery

high-speed transceiver channels are not connected on this HSMC.

AIC_DIN 143 DIN 4 I2S format serial data input to the sigma-delta stereo

D/A converter.

AIC_DOUT 144 DOUT 6 I2S format serial data output from the sigma-delta stereo

A/D converter.

AD_SCLK 92 SCLK 24 Control-port serial-data clock. For serial peripheral

interface (SPI) and 2-wire control modes, this is the

serial-clock input.

AD_SDIO 91 SDIN 23 I2S format serial data input to the sigma-delta stereo

D/A converter.

AIC_SPI_CS 151 CS_n 21 Serial Control Interface Chip Select (Active Low).

AIC_BCLK 149 BCLK 3 I2S serial-bit clock. In audio master mode, the AIC23B

generates this signal and sends it to the DSP. In audio slave

mode, the signal is generated by the DSP.
