9. For each DPLL, there are several frequency profiles to choose from by pull-down menu. These frequency profiles are
(see
Figure 16
below).
◦
G.8262 Option 1: to configure the DPLL for SyncE for Europe
◦
G.8262 Option 2: to configure the DPLL for SyncE for NA/Japan
◦
G.8263: to configure the DPLL for PEC-S-F, which occurs when typically a IEEE-1588 algorithm is controlling the
DCO with frequency offsets
◦
G.8273.2: to configure the DPLL for T-BC (Telecom Boundary Clock), which occurs when a IEEE-1588 stack is
directly controlling the DCO with phase offsets. It also puts the DPLL in combo mode to synchronize to the other PLL
running G.8262-Option 1 profile
◦
Lock to 1Hz: to configure the DPLL for GPS application and locking to 1PPS only.
◦
Wideband: to configure the DPLL to operate in line card mode or lock to a 10MHz + 1PPS from GPS
