
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.
