The C4DA/24 card can be used for stand-alone applications as well as for the D19m rack for TDM application. On one card, four digital channels are converted to four analog outputs. High-end 24 bit Delta-Sigma stereo con- verters are used for each channel, working in subrange mode. The convert- ers receive their input signals either from the AES/EBU inputs (stand-alone application) or from the TDM bus.
The C4DA/24 card can be used next to the other D19m cards in a D19m rack. If in stand-alone applications the synchronization should fail, the clock will be generated from one of the AES/EBU inputs.
The channel status bits contain the source channel defined by the card ad- dress as well as the sampling rate information.
