Interface Description
System Interfaces
ATM Interfaces
* RxCLK may be either sunk or sourced, depending upon the application.
† The transmit and receive signals for channels B, C, and D of the TDAT042G5 device are mapped to the remaining three ATM devices as
For the quad ATM UTOPIA 3 eight-bit interface mode, where the ATM device has only an 8-bit interface, the
RxDATA[15:0] and TxDATA[15:0] words are replaced with RxDATA[15:8] and TxDATA[15:8] in each channel of the
TDAT042G5. This is shown in the following table.
