AIO-T Module

The AIO-T module provides a digital TDM (Time-Division Multiplexed) interface for connection directly to audio converters or other ICs. Four outputs (MCLK, SCLK, SYNC, and OUT) and one input (IN) are provided on BNC connectors. The module functions as a TDM master, sourcing the clocks and synchronization signals. Logic voltage levels are jumper selectable between 1.8V and 3.3V.

The TDM interface may be programmed for number of channels, bits/sample, bits/frame, sync type (width, polarity, and placement), and clock polarity. The module always presents 10 channels of input and output to the host computer, regardless of the number of TDM channels. Unused channels are ignored.


Input Channels: 10

Output Channels: 10

Bits Per TDM Frame: 32, 64, 128, or 256 bits/frame

Bits Per TDM Word: 8, 16, 24, or 32 bits

FSYNC Width: 1 bit to ½ of frame length
