SI5338C-B05627-GM

Overview

The SI5338C-B05627-GM is a programmable quad clock generator utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended formats including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. The device operates from a 1.8 V, 2.5 V, or 3.3 V core supply with a typical current of 45 mA. It features low phase jitter of 0.7 ps RMS typ, flexible input references up to 710 MHz, and glitchless frequency adjustments via I2C/SMBus interface.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with 0 ppm precision.
• Supports highly configurable output drivers for up to four differential outputs, eight single-ended clocks, or combinations thereof.
• Features low phase jitter of 0.7 ps RMS typ and independent frequency increment/decrement for glitchless adjustments.
• Includes independent phase adjustment on each driver with <20 ps step accuracy and configurable spread spectrum.

Applications

• Ethernet switch/router
• PCIe Gen1/2/3/4
• Broadcast video/audio timing
• Processor and FPGA clocking
• MSAN/DSLAM/PON

Procurement Notes

Verify the specific B05627 ordering suffix against the manufacturer's latest documentation to confirm exact frequency and format configurations. Ensure compatibility with ClockBuilder Pro software for register programming. Confirm package availability and lead times through authorized distributors as stock levels vary.

Selection Notes

Select this component when replacing multiple crystal oscillators with a single programmable source. Ensure the required output voltage (1.5V, 1.8V, 2.5V, or 3.3V) matches the load requirements. Verify that the input reference frequency falls within the supported ranges for the chosen input type (differential, single-ended, or crystal).

Part Context

This part belongs to the Si5338 family of I2C-programmable any-frequency, any-output quad clock generators. It is designed to replace discrete oscillators in high-performance digital systems requiring precise clock distribution. The device integrates a PLL and MultiSynth synthesizers in a compact 4x4 mm QFN-24 package.

Replacement Considerations

Direct pin-to-pin replacements within the Si5338 family may require reprogramming via ClockBuilder Pro to match specific frequency plans. Verify that alternative SKUs support the same output formats and voltage levels required by the target application circuitry.
