SI5341B-D14280-GM

The Skyworks Solutions SI5341B-D14280-GM is a low-jitter clock generator designed for flexible clock tree generation. It features proprietary MultiSynth™ fractional synthesizer technology, capable of synthesizing a wide range of frequencies up to 1028 MHz on its differential outputs.

Key electrical specifications include an ultra-low phase jitter of 90 fs rms, an operating frequency of 350 MHz, and support for multiple output formats such as CML, HCSL, LVCMOS, LVDS, and LVPECL. The device operates within a voltage range of 1.71V to 3.47V and is specified for an operating temperature range of -40°C to 85°C.

This clock generator is housed in a 64-QFN (9x9 mm) package with exposed pad, suitable for surface mounting. Its architecture allows it to replace multiple clock ICs and oscillators, making it a true "clock tree on a chip." It can be programmed via I2C and SPI serial interfaces or pre-programmed using ClockBuilderPro software.

Applications include clock tree generation, any-frequency clock translation, and clocking for FPGAs, processors, and memory. It is also suitable for Ethernet switches/routers, OTN framers/mappers/processors, test equipment, instrumentation, and broadcast video.
