7.4.3 MODE Pin on Serializer

The MODE pin on the serializer can be configured to select if the DS90UB933-Q1 device is to be operated from the external oscillator or the PCLK from the imager. The pin must be pulled to VDD_n(1.8 V, not VDDIO) with a resistor R1 and a pulldown resistor R2 for external oscillator mode to create the ratio shown in Figure 7-6. If the device is to be operated from PCLK from imager mode, MODE pin can be pulled up to VDD_n (1.8V) with a 10-kΩ resistor directly or use the ratio shown in Figure 7-6 and Table 7-2. Suggested resistor values are given in Table 7-2. The recommended maximum resistor tolerance is 1%. Other resistor values can be used as long as the ratio is met under all conditions.
