ZL30321 Overview
ZL30321 GbE/SONET/SDH/PDH Network Interface Synchronizer Data Sheet.
ZL30321 Key Features
- Provides synchronous clocks for network interface cards that support synchronous Ethernet (SyncE) in addition to tele in
- Two independent DPLLs provides timing for the transmit path (backplane to line rate) and the receive path (recovered lin
- Supports the requirements of ITU-T G.8262 for Synchronous Ethernet equipment slave clocks (EEC option 1 and 2) when bine
- Supports the requirements of Telcordia GR-253 SONET clocks and ITU-T G.813 SDH equipment slave clocks (SEC)
- Synchronizes to any standard tele system reference with a multiple of 8 kHz up to 77.76 MHz or to Ethernet clock rates i
- Programmable output synthesizers (P0, P1) generate clock frequencies with any multiple of 8 kHz up to 100 MHz
- Pb Free Tin/Silver/Copper -40oC to +85oC
- Supports automatic hitless reference switching and short term holdover during loss of reference inputs
- DPLLs can be configured to provide synchronous or asynchronous clock outputs
- Generates several styles of output frame pulses with selectable pulse width, polarity and frequency
