SI5338P-B04734-GM

Application Specific Clock/Timing Overview

The SI5338P-B04734-GM is an I2C-programmable quad clock generator from Skyworks Solutions. It utilizes MultiSynth technology to synthesize any frequency on four independent output drivers with zero ppm precision. The device supports a wide range of input references, including external crystals (8–30 MHz), CMOS (5–200 MHz), and differential inputs up to 710 MHz. Outputs are configurable for LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats, with individual supply voltages of 1.5, 1.8, 2.5, or 3.3 V per driver. It operates from a single core supply of 1.8, 2.5, or 3.3 V in a 4x4 mm QFN-24 package.

• Telecom line cards and MSAN/DSLAM/PON systems

Application Specific Clock/Timing Procurement Notes

Verify the specific ordering suffix B04734 against the manufacturer's current datasheet to confirm the exact pre-programmed frequency configuration and pinout assignment. Ensure the I2C pull-up voltage compatibility matches the system bus requirements, particularly if operating below 2.5 V.

Application Specific Clock/Timing Selection Notes

Select this component when multiple distinct clock frequencies are required from a single IC. Verify that the target output frequencies fall within the supported ranges for the chosen signal format (e.g., LVDS up to 710 MHz, CMOS up to 200 MHz). Confirm that the input reference source matches one of the supported types and frequency ranges.

Application Specific Clock/Timing Part Context

This part belongs to the Si5338 family of low-jitter clock generators. The 'P' indicates a specific frequency plan or configuration variant within the series. The '-GM' suffix denotes the tape-and-reel packaging option for surface-mount assembly.

Application Specific Clock/Timing Replacement Considerations

Direct replacements must be from the Si5338 family with matching electrical characteristics. Verify that alternative part numbers support the same output formats and frequency ranges. Check for pin-to-pin compatibility in the QFN-24 package.
