9.1.2 Generating Two Positive Output Voltages
Two DCR01s can be used to create output voltages of +3.3 V and +5 V, as shown in Figure 9-2. The two DCR01s are connected in self-synchronization, thus locking the oscillators of both devices to a single frequency. The ERROR and ENABLE facilities can be used in a similar configuration for a single DCR01. The filter capacitors connected to the VREC pins (CFILTER) must be kept separate from each other and connected in close proximity to their respective DCR01.
A. CIN = 2.2 μF for 5-V input devices and
0.47 μF for 12-V and 24-V input devices. Low-ESR, ceramic capacitors are
required.
