Transmit Utopia Data Bus Input—MSB:
This input pin, along with
TxData14 through TxData0 comprise the Transmit Utopia Data Bus input
pins. When the ATM Layer Processor wishes to transmit ATM cell data
through the XR-T7234 E3 UNI, it must place this data on these pins. The
data, on the Transmit Utopia Data Bus is latched into the Transmit Utopia
Interface block the rising edge of TxClk.
Note:
This input pin is only available in the 160 pin package version.
