SI5334C-B04104-GMR

Overview

The SI5334C-B04104-GMR is a pin-controlled quad clock generator from Skyworks Solutions. It synthesizes any frequency on four differential outputs using MultiSynth technology, achieving zero ppm frequency error and 0.7 ps RMS typical jitter. The device supports flexible input references including crystals (8–30 MHz), CMOS (up to 200 MHz), SSTL/HSTL (up to 350 MHz), and differential clocks (up to 710 MHz). Outputs are independently configurable for formats such as LVPECL, LVDS, HCSL, CMOS, SSTL, or HSTL with independent supply voltages of 1.5, 1.8, 2.5, or 3.3 V. It operates on a core supply of 1.8, 2.5, or 3.3 V within the -40°C to +85°C range.

Feature Summary

• MultiSynth Technology: Enables independent, any-frequency synthesis on four differential outputs with zero ppm accuracy.

• Flexible Output Drivers: Supports LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats with independent voltage selection per driver.
• Glitchless Frequency Adjustment: Pin-controlled frequency increment/decrement in 1 ppm steps for variable clock applications.

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 specific factory-programmed frequency plan associated with the B04104 suffix against system requirements. Confirm that the required output formats and frequencies align with the device's electrical limits. Check for moisture sensitivity handling during storage and assembly. Ensure the core and output supply voltages match the design specifications.

Selection Notes

Select this component when low jitter and high flexibility are required for multi-standard clocking. Verify that the desired output frequencies fall within the supported ranges for the chosen signal format. Consider the power consumption differences between output types, such as LVPECL versus CMOS. Ensure the application does not require an I2C interface, as this device uses pin control.

Part Context

This part belongs to the Si5334 family of pin-controlled clock generators. The 'C' suffix indicates a specific configuration variant within the series. The 'GMR' suffix denotes tape-and-reel packaging suitable for automated surface-mount assembly. The device is designed to replace discrete clock solutions with a single integrated chip.

Replacement Considerations

Direct replacements must be sought from the Si5334 family with matching frequency plans. Verify compatibility of the QFN-24 package footprint. Ensure that any substitute supports the same output formats and jitter specifications required by the design.

FAQ

What is the maximum output frequency for different signal formats?

LVPECL and LVDS support up to 710 MHz. HCSL supports up to 250 MHz. CMOS supports up to 200 MHz. SSTL and HSTL support up to 350 MHz.

Does the SI5334C support spread spectrum modulation?

No, the 'C' suffix typically denotes a standard version without spread spectrum capabilities. Spread spectrum features are available in other variants like the Si5334K/L/M.

How is the device configured?

The device is pin-controlled and factory-programmed. Configuration data is stored in NVM and loaded into RAM upon power-up, requiring no external microcontroller or I2C interface.
