Overview
The SI5334M-B04346-GM is a pin-controlled quad clock generator from the Si5334 family, manufactured by Skyworks Solutions. It utilizes MultiSynth technology to synthesize any frequency on four differential outputs with zero ppm error and typical phase jitter of 0.7 ps RMS. The device supports flexible input references including crystals (8–30 MHz) or clocks up to 710 MHz. Outputs are independently configurable for formats such as LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL, with supply voltages of 1.8 V, 2.5 V, or 3.3 V. This specific variant includes spread spectrum capabilities.
Feature Summary
- Four independent output drivers supporting any frequency synthesis up to 350 MHz (select frequencies to 710 MHz).
- Low phase jitter performance: 0.7 ps RMS typical.
- Pin-controlled configuration with factory-programmed NVM; no I2C interface required.
- Supports Spread Spectrum Clocking compliant with PCI Express standards.
Applications
- Ethernet switch and router clocking.
- PCI Express 2.0/3.0 timing.
- Processor and FPGA clock generation.
- Broadcast video and audio synchronization.
Procurement Notes
Verify the ordering suffix 'M' confirms the inclusion of spread spectrum functionality. Confirm the specific frequency plan associated with the B04346 code matches the target system requirements. Check current availability status as distribution may vary.
Selection Notes
Select this part when pin control is preferred over I2C programming. Ensure the required output voltage levels (1.5V to 3.3V) match the load specifications. Verify that the input reference source (crystal vs. external clock) aligns with the board design constraints.
Part Context
This component belongs to the Si5334 family of low-jitter clock generators. The 'M' suffix in the model number indicates support for spread spectrum modulation. Other variants in the series include pin-controlled phase adjustment (D/E/F) or frequency adjustment (G/H/J) features.
Replacement Considerations
Direct replacements within the same family require matching the functional suffix (e.g., M for spread spectrum). Verify that alternative part numbers support the identical output frequency plan or can be reprogrammed if field-programmable options exist.
FAQ
Does the SI5334M-B04346-GM support an I2C interface?
No, the Si5334 is a pin-controlled device and does not provide an I2C interface. Configuration is handled via hardware pins and factory-programmed memory.
What is the maximum output frequency supported?
The device supports any frequency up to 350 MHz. Select frequencies can reach up to 710 MHz depending on the specific output format and divider settings.
How is the spread spectrum feature enabled?
The spread spectrum feature is enabled via pin control. The 'M' suffix indicates the device supports this functionality, which is compliant with PCI Express standards.
