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.
