ZL30136
Overview
- Provides synchronous clocks for network interface cards that support synchronous Ethernet (SyncE) in addition to telecom interfaces (T1/E1, DS3/E3, etc.)
- Supports the requirements of ITU-T G.8262 for Synchronous Ethernet equipment slave clocks (EEC option 1 and 2)
- Synchronizes to telecom reference clocks (2 kHz, N*8 kHz up to 77.76 MHz) or to Ethernet reference clocks (25 MHz, 50 MHz, 62.5 MHz, 125 MHz, and 155.52 MHz)
- Generates Ethernet clocks (12.5 MHz, 25 MHz, 50 MHz, 62.5 MHz, or 125 MHz)
- Programmable telecom synthesizer generates clock frequencies of any multiple of 8 kHz up to 100 MHz
- Selectable loop bandwidth of 14 Hz, 28 Hz, 890 Hz, or 0.1 Hz
- Generates several styles of output frame pulses with selectable pulse width, polarity and frequency
- Provides 3 sync inputs for output frame pulse alignment
- Flexible input reference monitoring automatically disqualifies references based on frequency and phase irregularities ZL30136 GbE and Telecom Rate Network Interface Synchronizer Data Sheet October 2015
