SI5344A-B06230-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5344A-B06230-GMR is a low-jitter, four-output clock synthesizer and jitter attenuator from Skyworks Solutions. It utilizes fourth-generation DSPLL and MultiSynth technologies to generate any frequency combination from any input source. The device supports differential inputs up to 750 MHz and LVCMOS inputs up to 250 MHz. Output frequencies range from 100 Hz to 1028 MHz for differential formats and up to 250 MHz for LVCMOS. It features ultra-low jitter performance of 90 fs rms and meets ITU-T G.8262 SyncE requirements. The component operates within a temperature range of -40°C to +85°C and is housed in a 44-QFN package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm tape and reel packaging status. Confirm that the factory preprogrammed configuration matches the required application parameters before finalizing procurement orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when four independent outputs are required with high-frequency flexibility up to 1028 MHz. Ensure the design accommodates the 44-QFN 7x7 mm package dimensions and thermal requirements. Verify compatibility with the I2C or SPI serial interface for configuration.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5344 family, which offers four inputs and four outputs in a compact 44-QFN package. It shares core DSPLL technology with the Si5345 and Si5342 series but provides a reduced channel count suitable for applications requiring fewer than ten outputs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional replacements include other Si5344 variants such as SI5344A-D-GM or SI5344B-D-GM, provided the frequency range and output format requirements align with the specific application constraints.
