 
GPS clock processing procedure 
The control subunit and the peripheral circuit subunit 
performs locking, phase discrimination and voltage control 
for PP1S signals that are received from the GPS receiver, and 
outputs PP1S and 10MHz reference signals. 
 
ToP clock processing procedure 
The ZXMBW E9200 receives PTP time packets from ToP 
Master that is synchronized to GPS PP1S, through the 
Ethernet cable. The ZXMBW E9200 generates local clock that 
is synchronous with ToP Master. 
The control subunit and the peripheral circuit subunit 
performs locking, phase discrimination and voltage control 
for signals input by the ToP clock process subunit and 
outputs PP1S and 10MHz reference signals. 
Power Module 
The ZXMBW E9200 power supply module performs AC-DC 
conversion. Figure 16 illustrates the composition of the ZXMBW 
E9200 power supply module.
