Description
The SI53306-B-GMR is a high-performance, low-jitter clock generator IC from Silicon Labs. It generates multiple output clocks from a single input reference, supporting frequencies up to 350 MHz. Key features include:
- Flexible Outputs: Up to 6 differential or 12 LVCMOS outputs.
- Low Jitter: <0.5 ps RMS (12 kHz–20 MHz).
- Wide Input Range: Supports crystal, LVCMOS, LVDS, or LVPECL inputs.
- I²C Programmability: Allows dynamic frequency and output configuration.
- Industrial-Grade: Operates from -40°C to +85°C.
Ideal for networking, telecom, and data center applications requiring precise clock synchronization. The -B-GMR variant includes specific packaging (QFN-24) and tape/reel options.
