SI5350C-B05497-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350C-B05497-GT is a factory-programmable CMOS clock generator featuring a dual PLL and MultiSynth architecture. It provides three LVCMOS outputs in a 10-MSOP package. The device supports reference inputs from a 25 MHz or 27 MHz crystal, or an external clock signal up to 100 MHz via the CLKIN pin. Output frequencies are configurable from 2.5 kHz to 200 MHz with zero ppm error. Operating supply voltages for both core (VDD) and output buffers (VDDO) range from 1.71 V to 3.6 V. Typical period jitter is less than 70 ps peak-to-peak, and the maximum operating temperature is +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates any-frequency, any-output clocks using a dual PLL and high-resolution fractional divider architecture.
• Supports user-configurable control pins for output enable, power down, frequency select, spread spectrum enable, and loss of lock status.
• Enables glitchless frequency changes and configurable spread spectrum on outputs referencing PLLA.

Clock Generators, PLLs, Frequency Synthesizers Applications

• PCIe Gen 1 compliant systems
• HDTV, DVD/Blu-ray, and set-top boxes
• 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 programming configuration associated with the B05497 suffix against the target design requirements before procurement. Confirm that the 10-MSOP package variant meets the board layout constraints. Ensure the selected voltage levels align with the 1.71 V to 3.6 V operating range specified in the datasheet.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed, factory-programmed timing solution is required without I2C interface overhead. The 10-MSOP package limits the device to three outputs; verify that four or eight outputs are not needed for the application. Ensure the reference input matches either a standard 25/27 MHz crystal or an external clock source within the 10-100 MHz range.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5350 family of clock generators. The 'C' designation indicates support for both crystal and external clock inputs. The 'B' prefix denotes factory pre-programming. The 'GT' suffix specifies the tape and reel packaging format for the 10-MSOP variant.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5350C variants with different factory programming codes (e.g., SI5350C-Bxxxxx-GT). For identical functionality but different packaging, consider the 16-QFN or 20-QFN versions if additional outputs are acceptable.
