SI5345D-B00015-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5345D-B00015-GMR is a low-jitter, 10-output clock synthesizer and jitter attenuator from the Si5345 family. It supports any-frequency generation with output frequencies up to 350 MHz. The device features four inputs (differential or LVCMOS) and ten configurable outputs compatible with LVDS, LVPECL, LVCMOS, CML, and HCSL. It operates on a 1.8 V core voltage and 3.3 V I/O supply within a -40°C to +85°C temperature range. Packaged in a 64-QFN (9x9 mm) housing, it includes integrated non-volatile memory for configuration storage.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogrammed configuration associated with the B00015 suffix against project requirements. Confirm package availability and lead times through authorized distributors. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when fractional synthesis is required with output frequencies capped at 350 MHz. Compare with the Si5345A variant if frequencies exceeding 350 MHz are necessary. Utilize ClockBuilder Pro software to define the specific frequency plan and verify that the 64-QFN footprint matches the PCB layout constraints.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5345 Rev D series, which integrates MultiSynth dividers and a DSPLL. The 'D' designation indicates support for integer and fractional synthesis modes with a maximum output frequency of 350 MHz. The 'B' prefix typically denotes a factory preprogrammed configuration, while 'GMR' indicates tape and reel packaging.
