ZL30691 Series

The ZL30691 offers one 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. Under the same family, the [ZL3066x](https://www.microchip.com/wwwproducts/en/ZL30663) offer one to three channels of Synchronous Ethernet (SyncE) packet clock synchronization for line card interface. Also available is [ZL3079x](https://www.microchip.com/wwwproducts/en/ZL30793) 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.
