Additional Details

The SI5335C-B05010-GMR typically operates from a 1.8V or 2.5V power supply. The 'B05010' portion of the part number indicates a specific factory-programmed configuration defining the default output frequencies and operating parameters. This configuration can be modified via the I2C interface, allowing for dynamic adjustment of output frequencies, signal levels, and other settings. The SI5335C family is known for its excellent jitter performance, making it well-suited for applications requiring clean and stable clock signals. The device's support for multiple output formats provides flexibility when interfacing with various downstream components. Additionally, the programmable output skew feature allows for fine-tuning of the timing relationships between the different clock outputs, which is critical in high-speed digital systems.
