概要

Description

The SI5326C-C-GM is a high-performance, low-jitter clock generator and multiplier from Silicon Labs. It supports input frequencies from 1 MHz to 710 MHz and generates output frequencies up to 1.4 GHz with exceptional phase noise performance.
Key features:
- Flexible Inputs: Accepts LVDS, LVPECL, HCSL, or single-ended clocks.
- Integrated PLL: Eliminates the need for external VCXOs.
- Low Jitter: <100 fs RMS (12 kHz–20 MHz).
- I²C Interface: For easy configuration.
Ideal for telecom, networking, and data center applications requiring precise clock synthesis. The device operates from a 3.3 V supply and comes in a 24-pin QFN package.
