can dm365 or dm368 's PCLK input IO recognize a Vpp=800mV and DC=1.34V clock signal ?

hi ,all

i wonder if dm365 or dm368 's PCLK input IO could recognize a Vpp=800mV and DC=1.34V clock signal correctly ?

    You will need to apply the datasheet specifications to your system design constraints, in particular the voltage at which you will operate PCLK.

    But an input signal that goes from 0.94V to 1.74V will not work. The datasheet will tell you what voltages are required. Look for the VIL and VIH parameters.

    Hi,

    According to the DM365 data sheet, page 72 and page 73, the VIH min is 0.7VDDS_ISIF18_33= 1.197V and VIL max is 0.3VDDS)ISIF18_33=0.513V so it could not recognize the signal you describe here.

    Thanks,

    Tai
