LTC6908IS6-1#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6908IS6-1#TRMPBF is a precision silicon oscillator from Analog Devices, housed in a 6-lead TSOT-23 package. It provides two complementary outputs with a 180-degree phase shift. The frequency is set by a single external resistor (RSET) ranging from 50kHz to 10MHz. Key electrical parameters include a supply voltage range of 2.7V to 5.5V, typical supply current of 400µA at 5V and 50kHz, and frequency accuracy within ±1.5% maximum at 25°C. It features optional spread spectrum frequency modulation (SSFM) for improved EMC performance.

Programmable Timers And Oscillators Feature Summary

• Two-output configuration with 180° phase shift between OUT1 and OUT2
• Frequency programmable via single external resistor (RSET) from 50kHz to 10MHz
• Spread Spectrum Frequency Modulation (SSFM) with fixed ±10% spreading for EMC improvement
• Low power consumption with typical supply current of 400µA at V+ = 5V

Programmable Timers And Oscillators Applications

• Switching power supply clock reference
• Portable and battery-powered equipment
• Precise programmable oscillator circuits
• Charge pump driver applications

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRMPBF indicates a tape and reel packaging format containing 500 pieces. Confirm that the IS6 designation corresponds to the industrial temperature grade (-40°C to 85°C). Ensure the -1 variant is selected for complementary outputs rather than the -2 variant for quadrature outputs.

Programmable Timers And Oscillators Selection Notes

Select this component when complementary (180°) output phases are required. The IS6 package offers an industrial temperature range suitable for general commercial applications. For higher temperature requirements, consider the HS6 variant. Ensure the RSET resistor value falls within the optimal range of 20kΩ to 400kΩ for best frequency accuracy.

Programmable Timers And Oscillators Part Context

This part belongs to the LTC6908 family of resistor-set silicon oscillators. The -1 suffix denotes the version with complementary outputs (0°/180°), distinct from the -2 version which provides quadrature outputs (0°/90°). The IS6 package specifies the TSOT-23 form factor with industrial temperature grading.

Programmable Timers And Oscillators Replacement Considerations

Direct functional replacements within the same family include LTC6908IS6-2#TRMPBF for quadrature outputs or LTC6908HS6-1#TRMPBF for extended temperature ranges. Cross-package equivalents like LTC6908IDCB-1#TRPBF offer DFN packaging but require layout adjustments.
