SI5334C-B04811-GMR

Overview

The SI5334C-B04811-GMR is a pin-controlled quad clock generator utilizing MultiSynth technology for independent, any-frequency synthesis on four differential outputs. It supports frequencies up to 350 MHz generally, with select configurations reaching 710 MHz. The device features low phase jitter of 0.7 ps RMS typ and true 0 ppm frequency accuracy. It accepts external crystals (8–30 MHz) or reference clocks (5–710 MHz). Each output driver is independently configurable for signal format (LVPECL, LVDS, HCSL, CMOS, SSTL/HSTL) and voltage (1.5, 1.8, 2.5, or 3.3 V). The core supply operates at 1.8, 2.5, or 3.3 V.

Feature Summary

• Low-power MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers.
• Highly-configurable output drivers support up to four differential outputs or eight single-ended clock outputs.
• Low phase jitter: 0.7 ps RMS typical; High-precision synthesis allows true 0 ppm frequency accuracy.
• Flexible input reference supporting external crystal (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz).

Applications

• Ethernet switch/router
• PCI Express 2.0/3.0
• Broadcast video/audio timing
• Processor and FPGA clocking
• MSAN/DSLAM/PON

Procurement Notes

Verify the specific factory-programmed frequency plan associated with the B04811 suffix against the system requirements. Confirm that the required output formats and voltages match the predefined configuration, as field reprogramming is not supported for this pin-controlled variant. Ensure the design accommodates the 24-QFN package thermal characteristics.

Selection Notes

Select this component when zero-delay mode or glitchless frequency increment/decrement is not required, as these features are reserved for other Si5334 variants (D/E/F/G/H/J/K/L/M). Verify that the target frequencies fall within the standard 350 MHz limit unless the specific B04811 plan supports higher frequencies. Ensure the application does not require I2C programmability.

Part Context

This part belongs to the Si5334 family of pin-controlled clock generators from Skyworks Solutions. Unlike I2C-programmable counterparts, this device relies on factory programming stored in NVM. The 'C' indicates a specific performance tier within the family, while the alphanumeric suffix defines the unique frequency plan and output configuration.

Replacement Considerations

Direct replacements must be selected from the Si5334 family with identical pin-out and package dimensions. Verify that the substitute part number has a factory-programmed frequency plan matching the original design specifications, as internal settings cannot be altered post-manufacture.
