LTC6908HS6-2#WTRPBF

Programmable Timers And Oscillators Overview

The LTC6908HS6-2#WTRPBF is an automotive-grade, resistor-set silicon oscillator featuring spread spectrum frequency modulation (SSFM). It provides two quadrature outputs (0°/90° phase shift) in a 6-lead TSOT-23 package. The device operates on a single 2.7V to 5.5V supply with a typical current of 400µA at 50kHz. Frequency is set by a single external resistor, covering a range from 50kHz to 10MHz. SSFM spreads the output frequency by ±10% using a pseudorandom noise signal to improve electromagnetic compatibility. The component is qualified for AEC-Q100 standards and functions within a temperature range of -40°C to 125°C.

Programmable Timers And Oscillators Feature Summary

• Automotive-grade qualification (AEC-Q100) with extended temperature range (-40°C to 125°C)
• Dual quadrature outputs (LTC6908-2 variant) with 0°/90° phase relationship
• Spread spectrum modulation reduces peak EMI by ±10% with selectable rates (fOUT/16, fOUT/32, fOUT/64)
• Single-resistor frequency programming from 50kHz to 10MHz

Programmable Timers And Oscillators Applications

• Synchronizing multiple switching regulators to reduce conducted EMI
• Clock reference for portable and battery-powered equipment
• Charge pump driver applications requiring precise timing

Programmable Timers And Oscillators Procurement Notes

Verify that the #W suffix confirms AEC-Q100 automotive qualification. Confirm the HS6 designation indicates the high-temperature grade (-40°C to 125°C) and TSOT-23 package. Ensure the '2' in the model number corresponds to the required quadrature output configuration rather than complementary outputs.

Programmable Timers And Oscillators Selection Notes

Select this part when automotive reliability and wide temperature operation are required. Use the LTC6908HS6-2 variant specifically for quadrature clocking needs. For standard industrial applications, consider the CS6 or IS6 variants which may offer different thermal characteristics or pricing structures without the automotive certification.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6908 family of precision oscillators. The HS6-2 designation specifies the high-temperature version with quadrature outputs in a TSOT-23 package. The #W suffix denotes automotive-grade manufacturing controls. Other variants include the CS6 (commercial) and IS6 (industrial) grades, as well as the DFN package options.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements must match the AEC-Q100 qualification and quadrature output requirement. Non-automotive equivalents like the LTC6908IS6-2#TRPBF lack the specific automotive reliability data. Verify pinout compatibility between TSOT-23 packages if substituting with other manufacturers' spread spectrum oscillators.
