Table 1. Custom CDR Ports
Port Direction Clock Domain Description
FIFO_RD_CLK Input Async Clock provided to PHY FIFO_CLK to drive XPHY and CDR logic.
CTRL_CLK Input Async Clock provided to PHY CTRL_CLK to drive XPHY and CDR logic.
intf_rdy Input Async Output of XPHY and input to custom CDR.
FIFO_EMPTY Input Async To start reading the data once FIFO_EMPTY is de- asserted.
PHY_RDEN Output Async To allow FIFO to start filling in PHY, input to the XPHY and output of custom CDR.
FIFO_RDEN Output Async Assert when you want to start reading data from PHY and output of custom CDR.
Data_to_fabric_*(Bitslice data) Input Async Output data of PHY per bitslice. Each bitslice provides 8-bit data.
CNTVALUEOUT Output Async Input to PHY per bitslice to update delay line value and output of custom CDR.
CNTVALUEIN Input Async Updated Value of CNTVALUE from PHY and input to custom CDR.
CE Output Async Control signals inputs for updating delay line per bitslice and output of custom CDR.
INC Output Async Control signals inputs for updating delay line per bitslice and output of custom CDR.
LD Output Async Control signals inputs for updating delay line per bitslice and output of custom CDR.
RXTX_SEL Output Async Control signals inputs for updating delay line per bitslice and output of custom CDR.
