Signal Clock Domain Direction Description
csr_n[4:0]
(31)
mgmt_clk
Input
Indicates the converter resolution. This 5-bit bus
represents the N value in zero-based binary
format. For example, if N = 16, the csr_n[4:0] =
"01111". This design example supports the
following values:
01011
01100
01101
01110
01111
Any programmed value beyond the supported
range may result in undeterminable behavior in
the transport layer. You must ensure that the
csr_n[4:0] value always match the system
parameter N value.
Connect this signal to the TX DLL csr_n[]
output pin.
TX Path Operation
The data transfer protocol between the Avalon-ST interface and the TX path transport layer is data
transfer with backpressure, where ready_latency = 0.
