The ZL30681 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 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 ZL3067x offer one to three channels of Synchronous Ethernet (SyncE) packet clock synchronization for timing card interface. Also available is ZL3077x 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.
