an internal state machine. Automatic mode switch supports Free-
Run, Locked and Holdover modes
• Supports manual and automatic selected input clock switch
• Supports automatic hitless selected input clock switch on clock fail-
ure
• Supports three types of input clock sources: recovered clock from
STM-N or OC-n, PDH network synchronization timing and external
synchronization reference timing
• Provides a 2 kHz, 4 kHz, or 8 kHz frame sync input signal, and a 2
kHz or 8 kHz frame sync output signal
• Provides a 1PPS sync Input signal, and a 1PPS sync output signal
