Figure 5. POR Timing Diagram

The Si4356 provides two operating modes, a receive mode and a standby mode. The operating mode can be

changed by toggling STBY (pin 13) as described in Figure 6. Care should be taken to minimize the trace connected

to STBY to avoid external noise coupling that could result in unintended mode changes. The MSTAT signal (pin 12)

indicates the current operating mode of the device as defined in Table 13 and illustrated in Figure 6.
