Electrical characteristics—AC specifications—Fast Ethernet Controller (FEC)
Section 3.16.3, “FEC timing
Table 58 (MII receive signal timing)
• Column added: SR/CC (system requirement or controller characteristic)
• Column added: Classification (parameters are guaranteed by design)
Table 59 (MII transmit signal timing)
• Column added: SR/CC (system requirement or controller characteristic)
• Column added: Classification (parameters are guaranteed by design)
• Footnote added to max and min values columns: “Output parameters are valid for
C
L
= 25 pF, where C
L
is the external load to the device. The internal package
capacitance is accounted for, and does not need to be subtracted from the 25 pF
value.”
Table 60 (MII async inputs signal timing)
• Column added: SR/CC (system requirement or controller characteristic)
• Column added: Classification (parameters are guaranteed by design)
Table 61 (MII serial management channel timing):
• Column added: SR/CC (system requirement or controller characteristic)
• Column added: Classification (parameters are guaranteed by design)
Table 62 (RMII receive signal timing):
• Column added: SR/CC (system requirement or controller characteristic)
• Column added: Classification (parameters are guaranteed by design)
Table 63 (RMII transmit signal timing,):
• Column added: SR/CC (system requirement or controller characteristic)
• Column added: Classification (parameters are guaranteed by design)
• Specification change: REF_CLK to TXD[1:0], TX_EN valid max value is 16 ns (was 14)
• Added footnote 2 to value column “Output parameters are valid for CL = 25 pF, where
CL is the external load to the device. The internal package capacitance is accounted
for, and does not need to be subtracted from the 25 pF value.”
