Skyworks Solutions, Inc. Application Specific Clock/Timing SI5338A-B11498-GM

The SI5338A-B11498-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 requirements and features highly configurable output drivers capable of delivering up to four differential outputs, eight single-ended clock outputs, or a combination of both. The device boasts a low phase jitter of 0.7 ps RMS typical and offers 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 frequency ranges from 5 MHz to 710 MHz. Outputs can be configured for various signal formats, including LVPECL, LVDS, HCSL, and CMOS, with independent voltage options of 1.5, 1.8, 2.5, or 3.3 V. The device also features an independent frequency increment/decrement capability for glitchless adjustments and independent phase adjustments with <20 ps accuracy. With a compact 4x4 mm QFN package, the SI5338A 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 °C. It is programmable via an I2C/SMBus-compatible interface, making it suitable for various applications, including Ethernet switches, PCIe clocking, and telecom line cards.
