ZL30136中文资料SyncE and IEEE 1588数据手册Microchip规格书

描述 Description

The ZL30136 GbE and Telecom Rate Network Interface Synchronizer is a highly integrated cost-effective device that provides timing for network interface cards. The DPLL is capable of locking to one of three input references and provides standard Ethernet clock rates for synchronizing Ethernet PHYs, and a highly programmable clock and frame pulse for telecom interfaces such as T1/E1, DS3/E3, etc.Click here for secure documentation

特性 Features

Typical Applications
• GbE network interface cards that support synchronous Ethernet (SyncE)
• GPON ONT/ONU
• T1/E1 line cards
• DS3/E3 line cards
Features & Benefits
• 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) when combined with a system synchronizer (e.g. ZL30130 or ZL30138)
• 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
• Configurable through a serial interface (SPI or I2C)
