Oscillator
The ZL4902x/4903x can be used in both external clock or two pin oscillator mode. In two pin oscillator mode, the
oscillator circuit is completed by connecting either a 3.579MHz crystal or ceramic resonator across OSC1 and
OSC2 pins. It is also possible to configure a number of these devices (4 maximum) employing only a single
oscillator crystal. The OSC2 output of the first device in the chain is connected to the OSC1 input of the next
device. Subsequent devices are connected similarily. The oscillator circuit can also be driven by an 3.579MHz
external clock applied on pin OSC 1. The OSC2 pin should be left open.
For ZL4901x devices, the CLK input is driven directly by an 3.579MHz external digital clock.
