Figure 25. DS90UB913Q/914Q Operation in PCLK mode
MODE Pin on Serializer
The mode pin on the Serializer can be configured to select if the DS90UB913Q device is to be operated from the
external oscillator or the PCLK from the imager. The pin must be pulled to V
DD
(1.8V, not V
DDIO
) with a 10 kΩ
resistor and a pull down resistor (R
MODE
) of the recommended value to set the modes shown in Figure 26. The
recommended maximum resistor tolerance is 1%.
