Silicon Labs Clock/Timing - Application Specific SI5338A-B05495-GM

The SI5338A-B05495-GM is a quad clock generator 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 requirements and offers highly configurable output options, including up to four differential outputs and eight single-ended clock outputs. The device features a low phase jitter of 0.7 ps RMS typical and ensures true zero ppm frequency accuracy across all outputs. The clock generator can accept a variety of input reference signals, including external crystals and CMOS inputs, with a 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 options of 1.5, 1.8, 2.5, or 3.3 V. It also includes features for glitchless frequency adjustments, independent phase adjustments, and configurable spread spectrum capabilities. The device is programmable via an I2C/SMBus-compatible interface and operates from a single supply core with a typical current consumption of 45 mA. It is housed in a compact 4x4 mm, 24-QFN package and is rated for a wide temperature range of -40 to +85 ¬8C, making it suitable for various applications including Ethernet switches, PCIe clocking, and telecom line cards.
