SI5350C-B04509-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350C-B04509-GT is a factory-programmable CMOS clock generator utilizing a dual PLL and MultiSynth architecture. It supports pin-based configuration for XTAL or CLKIN references, providing up to three LVCMOS outputs in a 10-MSOP package. The device generates frequencies from 2.5 kHz to 200 MHz with zero ppm error. Operating conditions include core and output supply voltages of 1.8 V, 2.5 V, or 3.3 V. Typical power consumption is 20 mA at 1.8 V with three outputs enabled. Jitter performance is specified at 70 ps peak-to-peak typical.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates free-running and synchronized clocks using a dual PLL and high-resolution fractional divider architecture.
• Supports configurable spread spectrum modulation on PLLA-referenced outputs to reduce electromagnetic interference.
• Allows glitchless frequency transitions via user-configurable control pins for frequency selection and output enablement.

Clock Generators, PLLs, Frequency Synthesizers Applications

• HDTV, DVD/Blu-ray, and set-top box timing
• Audio/video equipment and gaming consoles
• Printers, scanners, and projectors
• Residential gateways and networking communication devices

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory-programmed frequency plan associated with the B04509 suffix against the official Skyworks datasheet or ClockBuilder Pro export. Confirm that the 10-MSOP package variant matches the required pin count and thermal specifications for the target PCB layout before finalizing procurement orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed-frequency solution is preferred over I2C programmability to reduce system complexity. Ensure the reference input matches the available crystal (25 MHz or 27 MHz) or external clock source. Verify that the required number of outputs does not exceed the three available in the MSOP package.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5350 family of clock generators, which are designed to replace multiple discrete crystals, oscillators, and PLLs. The 'C' designation indicates support for both crystal and external clock inputs, while the 'GT' suffix denotes the 10-MSOP package type with tape and reel packaging.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements within the same family include other Si5350C variants with different output counts or packages, such as the 16-QFN or 20-QFN versions. Cross-family substitution with Si5351 requires I2C programming capability, which differs from the pin-programmable nature of the Si5350.
