Hi Everyone,

Our customer plan to use DS90C187 with Single in Dual out 18bpp. Then please let me know the connection of OA_3+/- and OB_3+/- output. Can they leave open?

Best Regards,

    Hi Satoshi-San,

    Please note figure 16 of the data sheet. In this mode, dual pixel 18 bpp, OA3 and OB3 are tri-stated. If these pins are not going to a connector or there is no trace on these pins then you can make them no connect. But if they go to a connector or there is trace on these pins then please use 100 Ohm resistor between plus and minus of OA and OB signals to terminate these pins.
