The Skyworks Solutions SI5338B-B12189-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 achieves 0 ppm precision for independent clock generation, making it suitable for replacing multiple crystal oscillators or acting as a frequency translator.
This versatile timing IC supports various output formats including CML, HCSL, HSTL, LVCMOS, LVDS, LVPECL, and SSTL, with frequencies up to 350 MHz. It accepts multiple input references, including external crystals, CMOS, SSTL/HSTL, and differential signals. The device operates from a 1.8, 2.5, or 3.3 V core supply and offers independent output voltage configuration per driver.
Designed for applications such as Ethernet switches, routers, and PCIe Gen1/2/3/4 systems, the SI5338B-B12189-GM features a low phase jitter of 0.7 ps RMS typical. It is programmable via an I2C/SMBus-compatible serial interface and comes in a compact 4x4 mm 24-QFN package, suitable for surface mounting.
The device operates within a wide temperature range of -40°C to +85°C. It also includes features like configurable spread spectrum, independent phase adjustment, loss of lock, and loss of signal alarms, enhancing its utility in complex timing designs.
