SI5350C-B01863-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350C-B01863-GTR is a factory-programmable CMOS clock generator featuring a dual PLL and MultiSynth architecture. It provides three LVCMOS outputs in a 10-MSOP package, supporting frequencies from 2.5 kHz to 200 MHz with 0 ppm error. The device accepts 25 MHz or 27 MHz crystal references or external clock inputs (10–100 MHz). Operating voltages for core and output buffers are selectable at 1.8 V, 2.5 V, or 3.3 V. Typical power consumption is 25 mA at 3.3 V, with period jitter typically under 70 ps peak-to-peak.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates up to eight non-integer-related frequencies using a dual PLL and fractional divider architecture
• Supports glitchless frequency changes and configurable spread spectrum for EMI reduction
• Features user-configurable control pins for output enable, power down, and frequency selection
• Provides separate voltage supply pins for level translation between core and output buffers

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
• Handheld instrumentation
• Residential gateways and networking communication devices

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific configuration code 'B01863' against the manufacturer's official documentation to ensure the programmed frequencies and pin assignments match your design requirements. Confirm that the GTR suffix indicates the correct reel packaging format for your assembly line. Check for any product change notifications or end-of-life status updates prior to finalizing procurement plans.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when a fixed-frequency, factory-programmed solution is required to replace multiple discrete crystals and oscillators. Ensure the application requires only three output clocks, as other package options offer four or eight outputs. Verify that the input reference matches the supported 25 MHz or 27 MHz crystal frequencies or an external clock signal within the 10–100 MHz range.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5350 family of clock generators, which utilizes Skyworks' MultiSynth technology. The 'C' variant specifically supports external clock inputs via the CLKIN pin in addition to crystal references. The 'B' series denotes factory-programmed units, distinguishing them from blank I2C-programmable versions like the Si5351.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5350C variants with different output counts, such as the 16-QFN (4 outputs) or 20-QFN (8 outputs) packages, provided the pinout compatibility is verified. For applications requiring I2C programmability instead of factory programming, the Si5351C series serves as a functional alternative.
