SI5338N-B04336-GM

Overview

The SI5338N-B04336-GM is a programmable quad clock generator from Skyworks Solutions. It synthesizes four independent output clocks with 0 ppm precision using MultiSynth technology. The device supports differential and single-ended outputs, including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats. Maximum input frequency reaches 710 MHz via differential inputs, while outputs support up to 710 MHz for LVDS/LVPECL/CML. Core supply voltage ranges from 1.71 V to 3.63 V (1.8/2.5/3.3 V nominal). Typical RMS jitter is 0.7 ps. It operates within -40 °C to +85 °C in a 24-lead QFN package.

Procurement Notes

Verify the specific NVM configuration code B04336 against the datasheet's ordering information table to confirm factory-programmed frequencies and settings. Confirm that the GMR suffix matches the required tape-and-reel packaging format for automated assembly processes.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single source. Ensure the target output signal format (LVDS, LVPECL, etc.) and voltage levels match the load requirements. Verify that the input reference frequency falls within the supported range of 5 MHz to 710 MHz depending on the interface type.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces discrete crystal oscillators and buffers, consolidating frequency synthesis into a single low-jitter IC. The 'N' designation typically indicates a specific pinout or feature set variant within the broader Si5338 product line.

Replacement Considerations

Direct replacements must be sought within the Si5338 family with matching NVM configurations. Cross-model substitution requires verification of pin compatibility and electrical specifications, particularly regarding output drive strength and jitter performance.
