Additional Details:

The SI5335D-B08368-GM uses a digital PLL (Phase-Locked Loop) architecture to generate its output frequencies from a reference clock. Each output can be configured independently via I2C or SPI. The 'B08368' portion of the part number denotes a specific factory-programmed configuration; it is imperative to consult the product datasheet to determine the precise frequency plan and other specifications. The 'GM' suffix usually refers to the package type and temperature range.

Proper power supply decoupling is essential to achieving the specified jitter performance. Also, careful PCB layout, including controlled impedance of clock traces and minimizing trace lengths, is very important. Skyworks Solutions provides layout guidelines in the datasheet. The device generally operates from either a 1.8V or 3.3V supply.
