SI5338A-B05808-GM

Overview

The SI5338A-B05808-GM is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes four independent output clocks with zero ppm frequency accuracy. The device supports differential and single-ended outputs including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. Maximum input frequency reaches 710 MHz via differential inputs. Output frequencies range from 0.16 to 710 MHz depending on the format. Core supply voltage operates between 1.71 V and 3.63 V. Typical phase jitter is 0.7 ps RMS. The component is housed in a 24-lead QFN package.

Procurement Notes

Verify the specific factory-programmed NVM configuration associated with the B05808 suffix against the target design requirements. Confirm that the I2C address and register map match the system controller capabilities. Ensure the operating temperature range of -40 to +85 °C aligns with the environmental specifications.

Selection Notes

Select this model when four distinct clock frequencies are required from a single IC. Verify that the desired output signal formats (LVPECL, LVDS, etc.) are supported by the available output drivers. Check that the input reference source matches the supported frequency ranges for differential or single-ended inputs.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'B' suffix indicates a custom factory-programmed configuration stored in non-volatile memory. The 'GM' suffix denotes the 24-lead QFN package type. This variant replaces discrete crystal oscillators in complex digital systems.

Replacement Considerations

Direct pin-to-pin replacements within the same family include other Si5338 variants with different factory programming codes. Ensure the replacement part supports the required output frequencies and signal formats.
