Description

The SI5340A-D-GM is a high-performance, low-jitter clock generator and jitter attenuator from Silicon Labs. It supports input frequencies from 8 kHz to 750 MHz and generates up to 10 output clocks (up to 350 MHz) with ultra-low phase noise (<100 fs RMS jitter).
Key features:
- Flexible I/O: Supports LVDS, LVPECL, HCSL, and LVCMOS outputs.
- Advanced PLL: Integrated DSPLL® technology for superior jitter attenuation.
- Programmable: Configurable via SPI or I²C, with on-chip EEPROM for autonomous operation.
- Redundancy: Supports hitless switching between redundant inputs.
Applications include telecom, networking, data centers, and industrial systems requiring precise timing. The device is available in a compact 40-pin QFN package.
For detailed configuration, Silicon Labs provides the ClockBuilder Pro software tool.
