5. Modes and Timing

At initial startup, the Si4356 reads the selector pins and loads all registers with the appropriate values for the

selected configuration, as shown in the Figure 4.

Figure 4. Power Up Timing

5.1. Power on Reset (POR)

A Power On Reset (POR) sequence is used to boot the device up from a fully off or shutdown state. To execute this

process, VDD must ramp within 1ms and must remain applied to the device for at least 10 ms. If VDD is removed,

then it must stay below 0.15 V for at least 10 ms before being applied again. See Figure 5 and Table 12 for details.
