The SI5346B-B03830-GM is a dual DSPLL clock generator from Quarktwin Technology Ltd. designed for high-performance applications requiring low jitter and flexible frequency outputs. It features two independent DSPLLs capable of generating any output frequency from a wide range of input frequencies, with typical jitter performance under 100 fs. The device supports input frequencies from 25 MHz to 54 MHz for external crystals and from 8 kHz to 750 MHz for differential inputs. Output frequencies can range from 100 Hz to 720 MHz for differential outputs and up to 250 MHz for LVCMOS outputs. The SI5346B includes programmable features via a serial interface and in-circuit programmable non-volatile memory, ensuring it powers up in a known configuration. It is suitable for applications such as OTN muxponders, network line cards, and synchronous Ethernet systems. The compact 44-QFN package measures 7x7 mm, making it suitable for space-constrained designs.
