8A34013 Port Synchronizer

The 8A34013 is a port synchronizer for frequency and time/phase for equipment that uses packet based and physical layer based equipment synchronization. The 8A34011 is a highly integrated device that provides tools to manage timing references, clock sources, and timing paths for IEEE 1588 and Synchronous Ethernet (SyncE) based clocks. The PLL channels can ac.

Features

▪ Four independent timing channels
• Each can act as a frequency synthesizer, jitter attenuator, Digitally Controlled Oscillator (DCO), or Digital Phase Lock Loop (DPLL)
• DPLL Digital Loop Filters (DLFs) are programmable with cut off frequencies from 17Hz to 22kHz
• Switching between DPLL and DCO modes is hitless and dynamic
• Generates output frequencies that are independent of input frequencies via a Fractional Output Divider (FOD)
• Each FOD supports output phase tuning with 1ps resolution ▪ 4 Differential / 8 LVCMOS outputs
• Frequencies from 0.5Hz to 1GHz (250MHz for LVCMOS)
• Jitter bel.
