LTC6908CS6-2#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6908CS6-2#TRMPBF is a silicon oscillator from Analog Devices, packaged in a 6-lead TSOT-23. It provides two quadrature outputs (0°/90° phase shift) with CMOS square wave signals. The frequency is set by a single external resistor (RSET), covering a range of 50kHz to 10MHz. Key electrical parameters include a supply voltage range of 2.7V to 5.5V, typical supply current of 400µA at 50kHz, and frequency accuracy within ±1.5% max at 25°C. It features optional spread spectrum frequency modulation (SSFM) for improved EMC performance.

Programmable Timers And Oscillators Feature Summary

• Dual Quadrature Outputs: Provides OUT1 and OUT2 shifted by 90 degrees.
• Spread Spectrum Modulation: Fixed ±10% frequency spreading with selectable rates (fOUT/16, fOUT/32, fOUT/64).
• Resistor Programming: Frequency determined by one external resistor using the formula fOUT = 10MHz • 10k/RSET.
• Low Power Consumption: Typical supply current of 400µA at 5V and 50kHz.

Programmable Timers And Oscillators Applications

• Switching power supply clock reference
• Portable and battery-powered equipment
• Charge pump driver

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRMPBF indicates a mini-reel tape and reel packaging configuration containing 500 pieces. Confirm the 'C' grade designation corresponds to the specified commercial temperature range of 0°C to 70°C. Ensure the ordering documentation matches the exact part number to avoid confusion with automotive or industrial grades.

Programmable Timers And Oscillators Selection Notes

Select this model for applications requiring quadrature output signals. Use the LTC6908CS6-1 variant if complementary (180°) outputs are needed instead. Consider the IS6 or HS6 variants if operation outside the 0°C to 70°C commercial range is required. Ensure the RSET value falls between 20kΩ and 400kΩ for optimal accuracy.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6908 family of resistor-set oscillators. The CS6-2 suffix denotes the Commercial temperature grade, SOT-23 package, and Quadrature output configuration. It is functionally similar to the LTC6908CS6-1 but differs in output phase relationship. Other packages include DFN and automotive qualified versions with W suffixes.
