SI5350C-B06847-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The Si5350C-B06847-GT is a factory-programmable CMOS clock generator with an integrated PLL, manufactured by Skyworks Solutions. It utilizes a dual PLL and MultiSynth fractional divider architecture to generate up to eight non-integer-related frequencies ranging from 2.5 kHz to 200 MHz with 0 ppm error. The device supports glitchless frequency changes and configurable spread spectrum. It operates on core and output supply voltages of 1.8 V, 2.5 V, or 3.3 V. This specific part number corresponds to the 10-MSOP package variant, providing three LVCMOS outputs (CLK0, CLK1, CLK2).

• Features user-configurable control pins for power down, output enable, and frequency select.
• Includes programmable spread spectrum capability to reduce electromagnetic interference.

Clock Generators, PLLs, Frequency Synthesizers Applications

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

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the ordering suffix matches the required package type and pin count. Confirm that the factory-programmed configuration aligns with the target system's frequency requirements. Ensure the reference crystal specifications meet the internal load capacitance guidelines provided in the datasheet.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed-frequency solution is preferred over I2C programmability. The 10-MSOP package limits the device to three outputs. Verify that the required output voltage levels match the available VDDO options. Check if the application requires more than three outputs, which would necessitate a different package variant.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5350 family of factory-programmable clock generators. Unlike the I2C-configurable Si5351 series, the Si5350C relies on pin-based control and pre-programmed configurations. The 'B' designation indicates it accepts both crystal and external clock inputs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5350C variants with different package types, such as SI5350C-Bxxxxx-GM1 (16-QFN) or SI5350C-Bxxxxx-GM (20-QFN), provided the output count and pinout compatibility are verified.
