描述 Description

The ZL30671 offers one DPLL channel of Synchronous Ethernet (SyncE) packet clock synchronization. Using Microsemi’s miTimePLL timing technology, these devices offer new and improved features for 5G transport and wireless infrastructure equipment.? Each device integrates all features required by a timing card PLL and line card PLL. High integration along with ultra-low jitter make these devices ideal for use in chassis based systems with active and redundant timing cards as well as in single board (“pizza box”) applications where a timing device needs to have features of both a timing and a line card PLL.
