SI5338C-B04168-GM

Overview

The SI5338C-B04168-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 flexible input references including differential clocks up to 710 MHz and single-ended inputs up to 200 MHz. Outputs are configurable for LVPECL, LVDS, CML, HCSL, CMOS, SSTL, or HSTL formats. Key electrical parameters include a core supply voltage range of 1.71 V to 3.63 V, typical operating current of 45 mA, and RMS jitter as low as 0.7 ps. It operates within an ambient temperature range of –40 °C to +85 °C.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout configuration, NVM programming status, and package variant. Ensure compatibility with I2C/SMBus interface requirements and check for moisture sensitivity level handling during assembly. Cross-reference the part number with the latest Skyworks Solutions datasheet revision to confirm availability and functional specifications.

Selection Notes

Select this component when designing systems requiring independent frequency synthesis across multiple outputs without external oscillators. Ensure the target application supports the required output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) per driver. Verify that the input clock source matches the supported frequency ranges and signal formats. Consider the thermal characteristics and PCB land pattern recommendations for the 24-QFN package during layout.
