Skyworks Solutions, Inc. Clock/Timing - Application Specific SI5338C-B04416-GM

The SI5338C-B04416-GM is a quad clock generator from Quarktwin Technology Ltd. that utilizes low power MultiSynth,Ñ¢ technology to provide independent, any-frequency synthesis on four differential output drivers. It supports PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliance, making it suitable for high-speed applications. The device features highly configurable output drivers capable of delivering up to four differential outputs or eight single-ended clock outputs, with a low phase jitter of 0.7 ps RMS typical. This clock generator allows for true zero ppm frequency accuracy across all outputs and offers flexible input reference options, including external crystals and various CMOS and differential input frequencies. The outputs can be independently configured to support multiple signal formats and supply voltages, ranging from 1.5V to 3.3V. Additional features include glitchless frequency adjustments in 1 ppm steps, independent phase adjustments with <20 ps accuracy, and configurable spread spectrum capabilities. The SI5338C-B04416-GM operates from a single supply core with excellent power supply rejection ratio (PSRR) and is designed for a wide temperature range of -40 to +85 ¬8C. It is programmable via an I2C/SMBus-compatible interface, and the small 4x4mm QFN package makes it suitable for space-constrained applications. This product is ideal for use in Ethernet switches, PCIe applications, broadcast video/audio timing, and various clocking needs in processors and FPGAs.
