Skyworks Solutions, Inc. 350 MHz Clock and Timing IC SI5338B-B08946-GM

The SI5338B-B08946-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 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 SI5338B can accept a variety of input reference signals, including external crystals and CMOS inputs, with a wide frequency range 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 allows for glitchless frequency adjustments in 1 ppm steps and independent phase adjustments with <20 ps accuracy. With a compact 4x4 mm QFN package, the SI5338B 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, and programming is facilitated by the ClockBuilder Pro software. This clock generator is ideal for applications such as Ethernet switches, PCIe devices, broadcast video/audio timing, and telecom line cards.
