Other Parts Discussed in Thread: TLV431

Hi,

    If I do not need analog RF out. Could I just connect Pin AH19 (VDAC_Vref) to GND through a 0.1uF capacitor? Not use TLV431? All analog Video out are not used. Iout-a toIout-g and RFout.

    Kevin,

    If you are not using the Video DACs and they are powered down, then you should leave this pin unconnected.  This device actually does not support RF out, so you just need to consider whether you would need to use the SD or HD-DACs (IOUTA-G).

    Regards,
