ZL30138数据手册集成电路（IC）的应用特定时钟/定时规格书PDF

描述 Description

The ZL30138 SONET/SDH/Ethernet Stratum 2/3E/3 System Synchronizer and SETS device is a highly integrated device that provides all of the functionality that is required for a central timing card in carrier grade network equipment. The basic functions of a central timing card include:
• Input reference monitoring for both frequency accuracy and phase irregularities
• Automatic input reference selection
• Support of both external timing and line timing modes
• Hitless reference switching
• Wander and jitter filtering
• Optional Input phase transient filtering (Stratum 3E phase build-out)
• Master/slave crossover for minimizing phase alignment between redundant timing cards
• Independent derived output timing path for support of the SETS functionalityClick here for secure documentation

特性 Features

Typical Applications
• ITU-T G.8262 System Timing Cards which support 1 GbE and 10 GbE interfaces
• Telcordia GR-253 Carrier Grade SONET/SDH Stratum 2/3E/3 System Timing Cards
• System Timing Cards which supports ITU-T G.781 SETS (SDH Equipment Timing Source)
Features & Benefits
• 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 2/3/3E and GR-253, ITU-T G.812, G.813, and G.781 SETS
• 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, 62.5 MHz, 125 MHz)
• Generates standard SONET/SDH clock rates (e.g. 19.44 MHz, 38.88 MHz, 77.76 MHz, 155.52 MHz, 622.08 MHz) or Ethernet clock rates (e.g. 25 MHz, 50 MHz, 125 MHz, 156.25 MHz, 312.5 MHz) for synchronizing Gigabit Ethernet PHYs
• Programmable output synthesizers (P0, P1) generate telecom clock frequencies from any multiple of 8 kHz up to 100 MHz
