LTC6908HS6-1#WTRM

Programmable Timers And Oscillators Overview

The LTC6908HS6-1#WTRM is an automotive-grade silicon oscillator in a 6-lead TSOT-23 package. It provides two complementary outputs (0°/180° phase shift) with rail-to-rail, 50% duty cycle square waves. Frequency is set by a single external resistor (RSET), covering a range of 50kHz to 10MHz at a 5V supply. The device operates on a single 2.7V to 5.5V supply and features optional spread spectrum frequency modulation (SSFM) for improved EMC performance. Key electrical parameters include a typical supply current of 400µA at 50kHz, frequency accuracy within ±1.5% max at 25°C, and temperature stability of ±40ppm/°C over the –40°C to 125°C operating range.

Programmable Timers And Oscillators Feature Summary

• Automotive qualified (AEC-Q100) with extended temperature range (-40°C to 125°C)
• Dual complementary outputs (LTC6908-1) with 180° phase shift
• Single resistor programmable frequency from 50kHz to 10MHz
• Spread spectrum frequency modulation (SSFM) with fixed ±10% spreading

Programmable Timers And Oscillators Applications

• Switching power supply clock reference
• Multi-phase synchronization for switching regulators
• Portable and battery-powered equipment
• Precision programmable oscillator circuits

Programmable Timers And Oscillators Procurement Notes

Verify the #W suffix indicates automotive grade qualification when sourcing. Confirm the S6 package designation matches the required TSOT-23 footprint. Ensure the HS6-1 variant corresponds to the complementary output requirement rather than quadrature. Check specific automotive reliability reports from the manufacturer for detailed qualification data.

Programmable Timers And Oscillators Selection Notes

Select this part for applications requiring high-temperature operation up to 125°C. Use the LTC6908HS6-1#WTRM specifically when complementary (180°) outputs are needed for dual regulator synchronization. Choose the HS6-2 variant if quadrature (90°) outputs are required instead. Ensure RSET values remain 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 'H' denotes the high-temperature industrial grade (-40°C to 125°C). The 'S6' indicates the 6-lead TSOT-23 plastic package. The '#W' suffix identifies it as an automotive-grade version manufactured under controlled conditions. The 'TRMPBF' or similar tape/reel packaging options are available for surface mount assembly.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements include other LTC6908HS6-1 variants with different packaging suffixes such as #TRPBF. For non-automotive applications, the standard LTC6908HS6-1 can be used. If quadrature outputs are acceptable, the LTC6908HS6-2 series serves as a functional alternative.
