Microchip Technology ZL3073x Network Synchronizers

Microchip Technology ZL3073x Network Synchronizers are solutions that feature four, five, six, seven, and eight independent DPLLs and five extremely low output jitters. These synchronizers are available along with IEEE 1588-2008 Precision Time Protocol Stack and synchronization algorithm software modules. The ZL3073x synchronizers feature <100ps input-to-output alignment, easy-to-use evaluation/programming software, and automatic self-configuration at power-up from internal Flash memory. These synchronizers operate at 1.25GHz maximum input frequency, 750MHz maximum output frequency, and 1.8V to 3.3V supply voltage range. The ZL3073x synchronizers are ideal for applications such as 5G distributed units, centralized units, radio units, 5G SyncE, and IEEE1588 timing card/line card applications.
