Skyworks Solutions, Inc. Clock and Timing IC SI5338H-B-GM

The SI5338H-B-GM is a quad clock generator that utilizes I2C-programmable MultiSynth,Ñ¢ technology, allowing for the independent synthesis of any frequency on four differential output drivers. It supports PCIe Gen 1/2/3/4 common clock requirements and offers a low phase jitter of 0.7 ps RMS typical. The device features highly configurable output drivers that can provide up to four differential outputs, eight single-ended clock outputs, or a combination of both, with independent voltage options of 1.5, 1.8, 2.5, or 3.3 V. The clock generator can accept a variety of input reference signals, including external crystals and CMOS inputs, with a frequency range from 5 to 710 MHz. Each output can be independently configured to support various signal formats such as LVPECL, LVDS, HCSL, and CMOS, with frequency capabilities ranging from 0.16 to 710 MHz. The device also includes features for glitchless frequency adjustments in 1 ppm steps, independent phase adjustments with <20 ps accuracy, and configurable spread spectrum capabilities. The SI5338H-B-GM operates from a single supply core with a typical power consumption of 45 mA and is rated for a wide temperature range of -40 to +85 ¬8C. Its compact 4x4 mm, 24-QFN package makes it suitable for space-constrained applications. This clock generator is ideal for applications such as Ethernet switches, PCIe clocking, broadcast video/audio timing, and various telecom and data communication systems.
