SI5338N-B05866-GM

Overview

The SI5338N-B05866-GM is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency on four independent output drivers with zero ppm precision. The device supports differential and single-ended outputs including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. Maximum input and output frequencies reach 710 MHz for differential formats. Key electrical parameters include a typical phase jitter of 0.7 ps RMS, a core supply voltage range of 1.71 V to 3.63 V, and an operating temperature range of -40 °C to +85 °C.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers.
• Supports flexible input references: external crystals (8-30 MHz), CMOS (5-200 MHz), SSTL/HSTL (5-350 MHz), and differential inputs (5-710 MHz).
• Highly configurable output drivers supporting up to four differential or eight single-ended outputs.
• Independent frequency increment/decrement feature allows glitchless adjustments in 1 ppm steps.

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS compliant systems
• Ethernet switch/router timing
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific factory-programmed NVM configuration associated with the B05866 suffix against the design requirements. Confirm that the QFN-24 package dimensions and thermal characteristics align with the PCB land pattern specifications provided in the datasheet.

Selection Notes

Select this component when replacing multiple crystal oscillators with a single programmable source. Ensure the required output signal format (LVPECL, LVDS, etc.) and frequency range are supported by the specific driver configuration. Verify I2C/SMBus compatibility for system control.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'N' suffix typically denotes a custom factory-programmed variant with specific frequency and configuration data stored in non-volatile memory, distinguishing it from generic user-programmable versions.

Replacement Considerations

Direct replacements within the same family include SI5338N-Bxxxxx-GMR variants with different NVM configurations. Cross-family substitution requires verifying pinout compatibility and ensuring the replacement supports the required output formats and jitter specifications.
