ZL30146 SyncE SONET/SDH Line Card PLL

The ZL30146 OC-192/STM-64 PDH/SONET/SDH/Synchronous Ethernet Network Interface Synchronizer is a highly integrated device that provides timing for both PDH/SONET/SDH and Ethernet network interface cards. A functional block diagram is shown in Figure 1. This device is ideally suited for designs that require both a transmit timing path (backplane to PHY) and .

Features

• Synchronizes to standard telecom or Ethernet backplane clocks and provides jitter filtered output clocks for SONET/SDH, PDH and Ethernet network interface cards Supports the requirements of ITU-T G.8262 for synchronous Ethernet Equipment slave Clocks Meets the SONET/SDH jitter generation requirements up to OC-192/STM-64 Two independent DPLLs provides timing for the transmit path (backplane to line rate) and the receive path (recovered line rate to backplane) Synchronizes to telecom reference clocks (2 kHz, N
*8 kHz up to 77.76 MHz, 155.52 MHz) or to Ethernet reference clocks (25 MHz, 50 MHz, .
