Skyworks Solutions, Inc. Clock/Timing - Application Specific SI5338A-B07875-GM

The SI5338A-B07875-GM is a quad clock generator from Quarktwin Technology Ltd. that utilizes low power MultiSynth,Ñ¢ technology to provide independent, any-frequency synthesis across 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, eight single-ended clock outputs, or a combination of both, with a low phase jitter of 0.7 ps RMS typical. This clock generator allows for true zero ppm frequency accuracy on all outputs and offers flexible input reference options, including external crystals and various CMOS and differential inputs. The outputs can be independently configured to support multiple signal formats and supply voltages ranging from 1.5V to 3.3V. The device also includes features such as glitchless frequency adjustments in 1 ppm steps, independent phase adjustments with <20 ps accuracy, and configurable spread spectrum capabilities. The SI5338A-B07875-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 °C. Its compact 4x4 mm QFN package and low power consumption of 45 mA core supply make it suitable for space-constrained applications. The device is programmable via an I2C/SMBus-compatible interface, and programming is facilitated by the ClockBuilder Pro software.
