SI5338C-B10647-GM

Overview

The SI5338C-B10647-GM is a programmable clock generator utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended outputs with frequencies up to 710 MHz. The device operates from a 1.8, 2.5, or 3.3 V core supply and features low phase jitter of 0.7 ps RMS typical. It accepts various input references including external crystals (8–30 MHz), CMOS (up to 200 MHz), SSTL/HSTL (up to 350 MHz), and differential inputs (up to 710 MHz). Configuration is performed via an I²C/SMBus interface.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape/reel specifications. Ensure compatibility with the intended I2C bus voltage levels, as the device supports standard and fast mode operations across varying supply voltages.

Selection Notes

Select this component when designing systems requiring multiple independent clock frequencies from a single source. Verify that the required output signal formats (LVPECL, LVDS, CMOS, etc.) and frequency ranges fall within the specified limits. Confirm that the input reference source matches one of the supported types, such as differential clocks up to 710 MHz or single-ended CMOS up to 200 MHz.

Part Context

This part belongs to the Si5338 family of I2C-programmable quad clock generators. The 'C' in the model number typically denotes a specific frequency plan or configuration variant within the series, while the suffix indicates packaging details. It serves as a replacement for multiple discrete crystal oscillators in complex digital systems.

Replacement Considerations

Direct replacements must be selected from the Si5338 family with matching output counts and frequency capabilities. Verify that alternative parts support the same I2C programming interface and physical QFN-24 package dimensions to ensure mechanical compatibility.
