SI5347A-B06307-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5347A-B06307-GM is a factory preprogrammed clock synthesizer and jitter attenuator from Skyworks Solutions. It integrates four independent Dual-Source Phase-Locked Loops (DSPLLs) to generate up to eight output clocks with frequencies ranging from 0.0001 MHz to 720 MHz. The device accepts input frequencies via differential, LVCMOS, or external crystal sources (25–54 MHz). It operates on a core voltage of 1.8 V ±5% and an analog supply of 3.3 V ±5%, functioning within a temperature range of –40 °C to +85 °C. The component is housed in a 64-lead QFN package measuring 9×9 mm.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm the exact preprogrammed configuration sequence. Factory preprogrammed devices utilize unique numerical sequences assigned by ClockBuilder Pro software. Confirm that the required revision level matches the intended design specifications before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when multiple independent timing paths are required within a single package. The Si5347A variant supports output frequencies up to 720 MHz, distinguishing it from lower-frequency variants. Ensure the application requires the quad DSPLL architecture rather than the dual DSPLL Si5346 version to optimize board space and cost.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5347 family of high-performance jitter-attenuating clock multipliers. It utilizes fourth-generation DSPLL technology to provide ultra-low jitter performance. The 'A' designation indicates support for output frequencies up to 720 MHz, while the 'D' revision denotes the specific hardware iteration with defined electrical characteristics.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional replacements include other Si5347A-D-GM variants with different preprogrammed sequences. For applications requiring fewer outputs, the Si5346A-D-GM serves as a dual-DSPLL alternative in a smaller package. Verify compatibility with existing ClockBuilder Pro configuration files when substituting.
