Silicon Labs Clock/Timing - Application Specific SI5338C-B04068-GM

The 1271995-SI5338C-B04068-GM is a quad clock generator that utilizes low power MultiSynth,Ñ¢ technology to provide independent frequency 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 formats such as LVPECL, LVDS, HCSL, and CMOS, with independent voltage settings of 1.5, 1.8, 2.5, or 3.3 V. It operates from a single supply core with excellent power supply rejection ratio (PSRR) and has a low typical core supply current of 45 mA. Additional features include glitchless frequency adjustments in 1 ppm steps, independent phase adjustments with <20 ps accuracy, and a configurable spread spectrum capability. The device is programmable via an I2C/SMBus-compatible interface and comes in a compact 4x4 mm, 24-QFN package, making it suitable for applications such as Ethernet switches, PCIe clocking, and telecom line cards. The operating temperature range is from -40 to +85 °C.
