Skyworks Solutions, Inc. Clock and Timing IC SI5338C-B04461-GMR

The 1271177-SI5338C-B04461-GMR is a quad clock generator from the MultiSynth,Ñ¢ series, designed for high-performance applications requiring low jitter and precise frequency synthesis. It features independent, any-frequency synthesis on four differential output drivers, supporting various signal formats including LVPECL, LVDS, HCSL, CMOS, and SSTL/HSTL. The device operates with a low phase jitter of 0.7 ps RMS typical and offers true zero ppm frequency accuracy across all outputs. This clock generator is programmable via an I2C/SMBus-compatible interface and can be configured to accept a wide range of input frequencies from external crystals or differential inputs. It supports independent voltage levels for each output driver, with options of 1.5, 1.8, 2.5, or 3.3 V. The Si5338 also includes features such as glitchless frequency adjustments, independent phase adjustments, and configurable spread spectrum capabilities. With a compact 4x4 mm QFN package and low power consumption of 45 mA typical, the Si5338 is suitable for various applications including PCIe clocking, Ethernet switches, and telecom line cards. Its wide operating temperature range of -40 to +85 °C further enhances its versatility in demanding environments.
