Skyworks Solutions, Inc. Clock and Timing IC SI5338B-B08686-GM

The Si5338B is a quad clock generator that utilizes low power MultiSynth,Ñ¢ technology, allowing for independent frequency synthesis on four differential output drivers. It supports a wide range of input reference frequencies, including external crystals and various CMOS and differential inputs, with output configurations that can deliver up to four differential outputs or eight single-ended clock outputs. The device features low phase jitter of 0.7 ps RMS typical and offers true zero ppm frequency accuracy across all outputs. Output drivers are highly configurable, supporting multiple signal formats such as LVPECL, LVDS, HCSL, and CMOS, with independent voltage options of 1.5, 1.8, 2.5, or 3.3 V. The Si5338B also includes features for glitchless frequency adjustments, independent phase adjustments, and a flexible spread spectrum capability. It operates from a single supply core with a typical current consumption of 45 mA and is rated for a wide temperature range of -40 to +85 ¬8C. The device is programmable via an I2C/SMBus-compatible interface, making it suitable for various applications including PCIe clocking, Ethernet switches, and telecom line cards.
