Calling Line Identifier  
CMX602A  
1.5.9 Xtal Osc and Clock Dividers  
Frequency and timing accuracy of the CMX602A is determined by a 3.579545MHz clock present at the XTAL  
pin. This may be generated by the on-chip oscillator inverter using the external components C1, C2 and X1 of  
Figure 2, or may be supplied from an external source to the XTAL input, in which case C1, C2 and X1 should  
not be fitted.  
The oscillator is turned off in the 'Zero-Power' modes.  
If the clock is provided by an external source which is not always running, then the ZP input must be set high  
when the clock is not available. Failure to observe this rule may cause a significant rise in the supply current  
drawn by CMX602A as well as generating undefined states of the RXD, DET and IRQN outputs.
