LTC6908HS6-1#WTRPBF

Programmable Timers And Oscillators Overview

The LTC6908HS6-1#WTRPBF is an automotive-grade silicon oscillator in a 6-lead TSOT-23 package. It provides two complementary outputs shifted by 180 degrees. The frequency is set by a single external resistor (RSET) ranging from 50kHz to 10MHz using the formula fOUT = 10MHz • 10k/RSET. It operates on a single 2.7V to 5.5V supply with typical current consumption of 400µA at 50kHz. Key features include optional spread spectrum frequency modulation (SSFM) for EMC improvement, ±40ppm/°C temperature stability, and fast start-up time of 260µs typical.

Programmable Timers And Oscillators Feature Summary

• Automotive qualified (AEC-Q100) with extended operating temperature range (-40°C to 125°C)
• Dual complementary outputs (0°/180° phase shift) with rail-to-rail CMOS logic levels
• Spread Spectrum Frequency Modulation (SSFM) with fixed ±10% spreading and selectable rates (fOUT/16, fOUT/32, fOUT/64)
• Frequency accuracy ≤1.5% max at 25°C with single resistor programming

Programmable Timers And Oscillators Applications

• Switching power supply clock reference for multi-phase regulators
• Portable and battery-powered equipment requiring low power consumption
• Charge pump drivers needing precise timing signals
• Systems requiring improved electromagnetic compatibility through SSFM

Programmable Timers And Oscillators Procurement Notes

Verify the #W suffix indicates AEC-Q100 qualification for automotive applications. Confirm the HS6-1 designation corresponds to the high-temperature industrial grade (-40°C to 125°C) and complementary output configuration. Ensure the TRPBF suffix matches the required tape and reel packaging quantity of 2500 units.

Programmable Timers And Oscillators Selection Notes

Select this part over standard grades when automotive reliability standards are mandatory. Choose the HS variant if the application environment exceeds 85°C. Use the LTC6908IS6-1#WTRPBF if the operating temperature does not exceed 85°C but automotive qualification is still required. Verify RSET values between 20k and 400k ensure optimal performance within the specified accuracy limits.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6908 family of resistor-set oscillators. The HS6-1#WTRPBF is the high-temperature, automotive-qualified version of the LTC6908HS6-1. It shares the same pinout and electrical characteristics as the non-automotive HS6-1 but undergoes controlled manufacturing processes to meet automotive quality requirements.

Programmable Timers And Oscillators Replacement Considerations

Direct replacement options include LTC6908IS6-1#WTRPBF for lower temperature automotive applications or LTC6908HS6-1#TRPBF for non-automotive high-temperature use. Ensure any substitute maintains the TSOT-23-6 package and complementary output configuration.
