SI5338B-B05581-GM

The Skyworks Solutions SI5338B-B05581-GM is a high-performance, low-jitter clock generator capable of synthesizing any frequency on each of its four output drivers. Utilizing patented MultiSynth™ technology, it allows for the generation of four independent clocks with 0 ppm precision, capable of replacing up to four different frequency crystal oscillators or operating as a frequency translator.

Each output clock is independently configurable to support various signal formats and supply voltages, including LVPECL/LVDS, HCSL, CMOS, and SSTL/HSTL. The device supports a wide range of input references, from external crystals to differential inputs, and offers independent output voltage configuration per driver (1.5V to 3.3V). It operates from a 1.8V, 2.5V, or 3.3V core supply.

This timing IC is programmable via an I2C/SMBus-compatible serial interface and is housed in a space-saving 4 x 4 mm QFN package. It features low phase jitter of 0.7 ps RMS typical and supports flexible spread spectrum generation. Applications include Ethernet switches/routers and PCIe Gen1/2/3/4 systems.

The SI5338B-B05581-GM is designed for applications requiring precise clock generation and distribution. Its configurable outputs and low power consumption make it suitable for various electronic designs. The device operates within a wide temperature range of -40 to +85 °C.
