SI5351A-B06887-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5351A-B06887-GT is a factory preprogrammed I2C programmable clock generator from the Si5351 series. It utilizes an internal oscillator with a crystal reference to generate up to three free-running LVCMOS outputs. The device supports frequencies ranging from 2.5 kHz to 200 MHz with 0 ppm error. Key electrical parameters include a maximum output frequency of 200 MHz, a maximum input frequency of 27 MHz, and typical period jitter of 70 ps. It operates on a core supply voltage of 2.5 V or 3.3 V (range 2.25 V to 3.6 V) and is housed in a 10-MSOP package.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates multiple non-integer-related clock frequencies using MultiSynth fractional dividers
• Configurable spread spectrum modulation selectable at each output
• Supports static phase offset and glitchless frequency changes
• Separate voltage supply pins provide level translation between core and output buffers

Clock Generators, PLLs, Frequency Synthesizers Applications

• XO replacement in cost-sensitive applications
• Audio/video equipment and gaming systems
• Printers, scanners, and projectors
• Residential gateways and networking/communication devices

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogrammed configuration associated with the suffix B06887 using ClockBuilder Pro software. Confirm that the required output frequencies and pinout match the design specifications before ordering. Ensure the 10-MSOP package dimensions are compatible with the PCB layout.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when a fixed-frequency, factory-configured solution is preferred over user-programmable variants. The Si5351A variant is suitable for designs requiring only free-running clocks derived from a crystal reference. Verify that the three-output capacity meets system requirements compared to four or eight-output packages.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5351 family of I2C programmable clock generators. The 'A' designation indicates it uses an internal oscillator for free-running operation without VCXO or external CLKIN support. The 'B' indicates the package type, and 'GT' denotes the tube packaging format for the 10-MSOP version.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other factory preprogrammed Si5351A parts with different custom codes (e.g., SI5351A-Bxxxxx-GT). For user-programmable equivalents, consider the blank Si5351A-B-GT. Cross-family replacements like the Si5350 require verification of interface differences.
