Additional Details:
The SI5335D-B07309-GM is built upon a digital PLL (Phase-Locked Loop) architecture, allowing precise frequency generation from a reference clock input. The outputs are independently programmable through an I2C or SPI interface. The 'B07309' section of the part number indicates a specific factory programmed configuration. Therefore, consulting the product datasheet is critical for determining the specific frequency plan and specifications. The 'GM' suffix generally refers to the package type and temperature range.
Proper power supply decoupling is required to achieve the stated jitter performance. Additionally, careful PCB layout is important, including impedance control of clock traces and minimizing trace lengths. Skyworks provides layout recommendations in the product datasheet. The power supply voltage typically required is 1.8V or 3.3V, depending on the specific configuration.
