Description

The SI53340-B-GM is a high-performance clock generator IC from Silicon Labs, designed for precision timing applications. It integrates a flexible PLL and multiple output clocks, supporting frequencies up to 350 MHz with low jitter (<1 ps RMS).
Key features:
- 4 differential outputs (LVPECL, LVDS, HCSL, or LVCMOS configurable)
- I²C programmable for dynamic frequency adjustments
- Wide input voltage range (2.375V–3.63V)
- Industrial temperature range (-40°C to +85°C)
Ideal for networking, telecom, and data center systems requiring synchronized, low-noise clocks. The B-GM variant comes in a 24-QFN package and offers enhanced power supply noise immunity.
For detailed specs, refer to the datasheet or Silicon Labs’ ClockBuilder Pro tool for configuration.
