Input signal voltage level to DDS[5:0] (Pin# 3,4,5,6,7,8) and DSD_CLK(Pin#9) is not described in hardware users guide.
Please let me know the range of input voltage.
They are logic level inputs, if you are not using them tie to ground through a resistor
Thank you for your answer.
Does Logic level input mean that CMOS logic levels from 1.8V to 3.3V ?
And, is pull-down resistor the range of 1-10K resistor ?
From the hardware guide digital inputs Vih_min = 1.35V
For the pull down resistor use any convenient resistor between 1 - 10 k is good
Thank you for your late reply.
