Skyworks Solutions, Inc. Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers SI5348B-B06338-GMR

The SI5348B-B06338-GMR is a network synchronizer clock from Quarktwin Technology Ltd., designed for applications requiring precise timing and synchronization, such as wireless backhaul and data center switches. It features three independent DSPLLs that can be configured for SyncE, IEEE 1588, or general-purpose clocking, providing flexibility in various network architectures. The device supports an ultra-low jitter of 100 fs and offers a wide input frequency range, accommodating external crystals from 48 to 54 MHz and reference clocks from 5 to 250 MHz. Output frequencies can range from 1 PPS to 718.5 MHz for differential outputs and 1 PPS to 250 MHz for LVCMOS outputs. The SI5348B also includes programmable jitter attenuation, a digitally controlled oscillator with high precision, and a serial interface for easy configuration via ClockBuilder Pro software. It operates within a temperature range of -40 to +85 ¬8C and is compliant with various ITU-T standards, making it suitable for demanding synchronization applications.
