Part Number: AM5728
Hello, TI Experts,
Our customer sent us a question from the datasheet(SPRS953B) "Table 7-81. Timing Requirements for rgmiin_rxc - RGMIIn Operation"
and "Figure 7-59. GMAC Receive Interface Timing, RGMIIn operation".
Question:
Regarding the specification of "Transition time, rgmiin_rxc" MAX:0.75ns,
Which understanding is correct for the definition of voltage changing range as below?
1) +0.8V～+2.0V ( The spec. [ VIL=0.8V, VIH=2.0V] is found from datasheet(SPRS953B) "Table 5-17" )
2) 20％-80％
They also said "BUFFER TYPE is Dual Voltage LVCMOS(3.3V_Mode)".
Best regards,
