LTC6908IS6-1#TRPBF

Programmable Timers And Oscillators Overview

The LTC6908IS6-1#TRPBF is a precision silicon oscillator from Analog Devices, housed in a 6-lead TSOT-23 package. It provides two complementary CMOS outputs with a 180-degree phase shift. The frequency is set by a single external resistor (RSET) ranging from 10k to 2M ohms, enabling output frequencies from 50kHz to 10MHz. Key specifications include a typical supply current of 400µA at 5V and 50kHz, ±40ppm/°C temperature stability, and a fast start-up time of 260µs. The device operates on a single 2.7V to 5.5V supply and features optional spread spectrum frequency modulation (SSFM) for improved EMC performance.

Programmable Timers And Oscillators Feature Summary

• Dual complementary outputs (OUT1/OUT2) with 180-degree phase shift
• Frequency programmable via single external resistor (50kHz to 10MHz range)
• Optional spread spectrum frequency modulation (SSFM) with fixed ±10% spreading
• Low power consumption: 400µA typical supply current at 5V
• High frequency stability: ±40ppm/°C over the operating temperature range

Programmable Timers And Oscillators Applications

• Clock reference for switching power supplies
• Precision programmable oscillator circuits
• Charge pump drivers
• Portable and battery-powered equipment requiring low power clocks

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging with 2500 units per reel. Confirm the IS6 designation corresponds to the industrial temperature grade (-40°C to 85°C) and TSOT-23 package. Check current availability status as distribution may vary. Ensure the application circuit matches the required output phase configuration for the -1 variant.

Programmable Timers And Oscillators Selection Notes

Select the LTC6908IS6-1#TRPBF when complementary (180-degree) outputs are required for driving dual single-output regulators or differential loads. Choose this over the -2 variant if quadrature outputs are not needed. Ensure the RSET value falls within the optimal range of 20k to 400k for best accuracy. Verify that the system's EMC requirements can be met with the fixed ±10% SSFM spreading if enabled.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6908 family of resistor-set silicon oscillators. The -1 suffix denotes the version with complementary outputs, distinct from the -2 version which provides quadrature outputs. The IS6 prefix specifies the industrial temperature range and TSOT-23 package. Other variants include CS6 (commercial temp), HS6 (extended temp), and DCB (DFN package).

Programmable Timers And Oscillators Replacement Considerations

Direct functional replacements within the same family include LTC6908CS6-1#TRPBF (commercial temp) and LTC6908HS6-1#TRPBF (extended temp). For automotive applications, consider the AEC-Q100 qualified versions such as LTC6908IS6-1#WTRPBF. Ensure pin compatibility and thermal characteristics match the existing design constraints.
