ZL30321 GbE/SONET/SDH/PDH Network Interface Synchronizer
Data Sheet
Features
• Provides synchronous clocks for network interface cards that support synchronous Ethernet (SyncE) in addition to telecom interfaces (e.g. T1/E1, DS3/E3, etc.)
• Two independent DPLLs provides timing for the transmit path (backplane to line rate) and the receive path (recovered line rate to backplane)
• Supports the requirements of ITU-T G.8262 for Synchronous Ethernet equipment slave clocks (EEC option 1 and 2) when combined with a system synchronizer such as the ZL30116, ZL30121, ZL30130, ZL30138
• Supports the requirements of Telcordia GR-253 SONET clocks and ITU-T G.813 SDH equipment slave clocks (SEC)
• Synchronizes to any standard telecom system reference with a multiple of 8 kHz up to 77.
