ZL30138 Key Features
- Supports the requirements of ITU-T G.8262 for synchronous Ethernet Equipment slave Clocks (EEC option 1 and 2)
- Pb Free Tin/Silver/Copper -40oC to +85oC
- Supports ITU-T G.823, G.824 and G.8261 for 2048kbits/s and 1544kbits.s interfaces
- Meets the SONET/SDH jitter generation requirements up to OC-192/STM-64
- 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
- Supports posite clock inputs (64 kHz, 64 kHz + 8 kHz, 64kHz + 8 kHz + 400 Hz)
- Generates several styles of tele frame pulses with selectable pulse width, polarity and frequency
- Provides two DPLLs which are independently configurable through a serial interface
- Internal state machine automatically controls mode of operation (free-run, locked, holdover)
- Flexible input reference monitoring automatically disqualifies references based on frequency and phase irregularities
