SI5350C-B03344-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350C-B03344-GTR is a factory-programmable CMOS clock generator utilizing a dual PLL and MultiSynth architecture. It supports up to eight non-integer-related output frequencies ranging from 2.5 kHz to 200 MHz with 0 ppm error. The device accepts a crystal reference (25 or 27 MHz) or an external clock input (10–100 MHz). It operates on core and output supply voltages of 1.8 V, 2.5 V, or 3.3 V. Typical power consumption is 25 mA at the core. The part number suffix GTR indicates tape-and-reel packaging.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Features user-configurable control pins for output enable, power down, and frequency selection.

Clock Generators, PLLs, Frequency Synthesizers Applications

• HDTV, DVD/Blu-ray, and set-top box timing
• Networking and communication equipment
• Servers and storage systems

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory-programmed configuration against the datasheet or ClockBuilder Pro export file associated with the B03344 code. Confirm that the GTR suffix matches the required tape-and-reel packaging format for the production line. Ensure the ordering information aligns with the intended package type and output count.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a custom clock tree with multiple non-integer-related frequencies is required. It replaces discrete crystals and oscillators. Verify that the application requires pin-based configuration rather than I2C programming. Check if the specific frequency plan fits within the simultaneous output constraints above 112.5 MHz.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5350 family of clock generators. The 'C' variant supports both crystal and external clock inputs. The 'B' indicates it is factory preprogrammed. The 'GTR' suffix specifies the reel packaging style. It is part of the MultiSynth product line designed for low jitter and flexible timing generation.
