SI5345D-B03377-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5345D-B03377-GMR is a 10-output jitter attenuator and clock multiplier from the Si5345 family, manufactured by Skyworks Solutions. It utilizes fourth-generation DSPLL and MultiSynth technologies to generate any combination of output frequencies from any input frequency. The device supports differential inputs ranging from 8 kHz to 750 MHz and LVCMOS inputs up to 250 MHz. Output frequencies range from 100 Hz to 350 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 64-QFN package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm factory pre-programming details. Confirm availability status as distribution channels may list obsolete or limited stock items. Ensure the package type matches the design requirements before finalizing procurement orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when applications require up to ten outputs with frequencies capped at 350 MHz. Verify that the input signal format aligns with the supported differential or LVCMOS ranges. Consider the operating temperature range and power supply requirements to ensure compatibility with the system environment.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5345/44/42 Rev D family of jitter attenuators. The Si5345 variant specifically provides four inputs and ten outputs, distinguishing it from the Si5344 (four outputs) and Si5342 (two outputs). All variants share similar core technologies but differ in I/O count and package size.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5345D variants with different factory pre-programming configurations, such as SI5345D-D-GM. Cross-family substitution with Si5344 or Si5342 requires verifying pin compatibility and output count requirements.
