ZL30663中文资料Network Synchronization数据手册Microchip规格书

描述 Description

The ZL30663 offers three channels of Synchronous Ethernet (SyncE) packet clock synchronization. Using Microsemi’s miTimePLL timing technology, this device offers new and improved features for 5G transport and wireless infrastructure equipment.  Each device integrates all features required by line card PLL. High integration along with ultra-low jitter make these devices ideal for use in frequency translation from backplane clock to frequencies required by PHY devices, jitter filtering, and holdover in case both active and redundant timing cards fail.

Under the same family, the ZL3069x offer one to three channels of Synchronous Ethernet (SyncE) packet clock synchronization for timing card interface. Also available is ZL3079x that support one to three independent timing channels of a combined hardware and software platform including IEEE 1588-2008 Precision Time Protocol Stack and Synchronization Algorithms.

特性 Features

Three independent DPLL channels
Precise phase/frequency measurement and tuning lower system latency to meet 4G LTE, 5G & Wireless Infrastructure
Precise chip-to-chip time interfaces use less backplane traces for 1PPS distribution for chassis systems
Split oscillator option lowers cost, lowers jitter, and provides redundancy
Excellent jitter performance of Two programmable ultra-low jitter synthesizers generate any frequency from 0.5 Hz to 1045 MHz
One programmable general purpose synthesizer generates any clock from 0.5 Hz to 180 MHz
8 differential or 16 single ended ultra-low jitter outputs plus two general purpose CMOS outputs
Programmable output advancement/delay to accommodate trace delays or compensate for system routing paths
Up to three programmable digital PLLs/NCOs with loop bandwidth from 14 Hz to 470 Hz synchronize to any clock rate from 0.5 Hz to 900 MHz
