Product Summary
The ZL30410QC is a Multi-service Line Card Phase-Locked Loop designed to generate multiple clocks for SONET, SDH and PDH equipment including timing for ST-BUS and GCI interfaces. The ZL30410QC operates in NORMAL (LOCKED), HOLDOVER and FREE-RUN modes to ensure that in the presence of jitter and interruptions to the reference signals, the generated clocks meet international standards. The applications of the ZL30410QC include: Line Card synchronization for SDH, SONET, DS3, E3, J2 (DS2), E1 and DS1 interfaces, Timing card synchronization for SDH and PDH Network Elements, Clock generation for ST-BUS and GCI timing.
