LTC6908HS6-1#TRPBF

Programmable Timers And Oscillators Overview

The LTC6908HS6-1#TRPBF is a precision silicon oscillator in a 6-lead TSOT-23 package, rated for an extended operating temperature range of –40°C to 125°C. It provides two complementary outputs shifted by 180° and features optional spread spectrum frequency modulation (SSFM) to improve electromagnetic compatibility. The output frequency is set by a single external resistor ranging from 10kΩ to 2MΩ, covering a range of 50kHz to 10MHz at a 5V supply. It operates on a single 2.7V to 5.5V supply with a typical current consumption of 400µA at 50kHz.

Programmable Timers And Oscillators Feature Summary

• Dual complementary outputs (OUT1/OUT2) with 180° phase shift
• Spread spectrum frequency modulation (SSFM) with ±10% spreading and selectable rates (fOUT/16, fOUT/32, fOUT/64)
• Frequency programming via single external resistor (RSET) using the formula fOUT = 10MHz • 10k/RSET
• Extended industrial temperature grade: –40°C to 125°C

Programmable Timers And Oscillators Applications

• Switching power supply clock reference
• Multi-phase synchronization for switching regulators
• Portable and battery-powered equipment
• Charge pump driver

Programmable Timers And Oscillators Procurement Notes

Verify the HS6 suffix indicates the high-temperature (-40°C to 125°C) variant within the SOT-23 package. Confirm the #TRPBF suffix corresponds to the standard tape and reel packaging quantity specified in the manufacturer's ordering information. Ensure the application requires the complementary output configuration specific to the -1 version.

Programmable Timers And Oscillators Selection Notes

Select this component when an extended temperature range up to 125°C is required. Use the LTC6908IS6-1 for standard industrial ranges (-40°C to 85°C) or LTC6908CS6-1 for commercial ranges (0°C to 70°C). Choose the -2 version if quadrature (90°) outputs are needed instead of complementary (180°) outputs.

Programmable Timers And Oscillators Part Context

This part belongs to the LTC6908 family of resistor-set oscillators. The 'H' designation specifically denotes the high-temperature performance grade compared to the 'I' (industrial) and 'C' (commercial) grades. The 'S6' indicates the 6-lead plastic TSOT-23 package type.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements include other temperature grades of the same package: LTC6908IS6-1#TRPBF (Industrial) and LTC6908CS6-1#TRPBF (Commercial). For automotive applications, consider the AEC-Q100 qualified versions with the #W suffix, such as LTC6908HS6-1#WTRPBF.
