The clock process unit is a timing & frequency subsystem, 

provides PP1S and 10MHz timing reference and frequency 
reference signals for the baseband and RF subsystem. 
The ZXMBW E9200 clock process unit consists GPS clock process 
subunit, ToP clock process subunit, control process subunit and 
peripheral circuit process subunit, as shown in Figure 15.
