ZL30142 Overview
ZL30142 SyncE SONET/SDH G.8262/Stratum 3 System Synchronizer Data Sheet.
ZL30142 Key Features
- Supports the requirements of ITU-T G.8262 for synchronous Ethernet Equipment slave Clocks (EEC option 1 and 2)
- Supports the requirements of Telcordia GR-1244 Stratum 3 and GR-253, ITU-T G.812, G.813
- Supports ITU-T G.823, G.824 and G.8261 for 2048 kbit/s and 1544 kbit/s interfaces
- Meets the SONET/SDH jitter generation requirements up to OC-48/STM-16
- Synchronizes to tele reference clocks (2 kHz, N-8 kHz up to 77.76 MHz, 155.52 MHz) or to Ethernet reference clocks (25 M
- Programmable output synthesizer generates tele clock frequencies from any multiple of 8 kHz up to 100 MHz
- Generates several styles of tele frame pulses with selectable pulse width, polarity and frequency
- Internal state machine automatically controls mode of operation (free-run, locked, holdover)
- Pb Free Tin/Silver/Copper -40oC to +85oC
- Flexible input reference monitoring automatically disqualifies references based on frequency and phase irregularities
