Skyworks Solutions, Inc. Clock/Timing - Application Specific SI5338B-B07844-GMR

The SI5338B-B07844-GMR is a quad clock generator from Quarktwin Technology Ltd. that utilizes low power MultiSynth,Ñ¢ technology to provide independent, any-frequency clock 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 and true zero ppm frequency accuracy across all outputs. The clock generator can accept a variety of input references, including external crystals and differential inputs, with a wide frequency range from 5 MHz to 710 MHz. Outputs can be configured for various signal formats such as LVPECL, LVDS, HCSL, and CMOS, with independent voltage settings of 1.5, 1.8, 2.5, or 3.3 V. The device also includes features for glitchless frequency adjustments, independent phase adjustments, and configurable spread spectrum capabilities. With a compact 4x4 mm QFN package, the SI5338B-B07844-GMR operates on 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. It is programmable via an I2C/SMBus-compatible interface, making it easy to integrate into various applications such as Ethernet switches, PCIe devices, and telecom equipment.
