ISERDES_NODELAY Clocking Methods
NUM_CE Attribute
SERDES_MODE Attribute
Networking Interface Type
X-Ref Target - Figure 8-5
The NUM_CE attribute defines the number of clock enables (CE1 and CE2) used. The
possible values are 1 and 2 (default = 2).
The SERDES_MODE attribute defines whether the ISERDES_NODELAY module is a
master or slave when using width expansion. The possible values are MASTER and
SLAVE. The default value is MASTER. See
The phase relationship of CLK and CLKDIV is important in the serial-to-parallel
conversion process. CLK and CLKDIV are (ideally) phase-aligned within a tolerance.
There are several clocking arrangements within the FPGA to help the design meet the
phase relationship requirements of CLK and CLKDIV. The only valid clocking
arrangements for the ISERDES_NODELAY block using the networking interface type are:
