DS90UB926Q-Q1: pull-up resistors on the RGB pins

Bart

Hi,

in the EVM documentation for this device (snlu114.pdf, page 27) there are pull-up resistors on the RGB pins (marked in red box below).

We did not see those resistors being mentioned in the device datasheet - is it necessary to have these resistors in the design or not?

Thanks.

1. These parts have Iinternal pulldowns (about 50K) . However if the part is powered down but the system is powered up the internal pulls are not active. Hence it is a good practice to use external pulls

Thanks

Vijay
