Introduction
The Si5348 combines the industry’s smallest footprint and lowest power network synchronizer clock with unmatched frequency synthesis flexibility and ultra-low jitter. The Si5348 is ideally suited for wireless backhaul, IP radio, small and macro cell wireless communications systems, and data center switches requiring both traditional and packe based network synchronization. The three independent DSPLLs are individually configurable as a SyncE PLL, IEEE 1588 DCO or a general-purpose PLL for processor/FPGA clocking. The Si5348 can also be used in legacy SETS systems needing Stratum 3/3E compliance. The optional digitally controlled oscillator (DCO) mode provides precise timing adjustment to 1 ppt for 1588 (PTP) clock steering applications. The unique design of the Si5348 allows the TCXO/OCXO reference input to determine the device’s frequency accuracy and stability. The Si5348 is programmable via a serial interface with in-circuit programmable non-volatile memory so it always powers up into a known configuration. Programming the Si5348 is easy with ClockBuilder Pro software. Factory pre-programmed devices are also available.
