LTC6908HS6-1#TRM

Programmable Timers And Oscillators Overview

The LTC6908HS6-1#TRM is a precision silicon oscillator from Analog Devices, housed in a 6-lead TSOT-23 package. It provides two rail-to-rail CMOS outputs with a 50% duty cycle, configured for complementary (180° phase shift) operation. The oscillation frequency is set by a single external resistor connected to the SET pin, covering a range of 50kHz to 10MHz at a 5V supply. Key features include optional spread spectrum frequency modulation (SSFM) for improved EMC performance and fast start-up times. The device operates on a single 2.7V to 5.5V supply and is qualified for automotive applications within an extended temperature range of -40°C to 125°C.

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRM indicates a tape and reel quantity of 500 pieces as per the datasheet ordering information. Confirm that the HS6 grade corresponds to the -40°C to 125°C operating temperature range required for the target application environment.

Programmable Timers And Oscillators Selection Notes

Select the LTC6908HS6-1#TRM when complementary outputs are required for driving dual switching regulators or charge pumps. Ensure the RSET resistor value falls within the optimal 20kΩ to 400kΩ range for best accuracy. Verify that the system can accommodate the pseudorandom jitter introduced by SSFM if enabled.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6908 family of resistor-set silicon oscillators. The 'HS6' designation identifies the high-temperature (-40°C to 125°C) version in the TSOT-23 package. The '-1' suffix specifies the complementary output configuration, distinguishing it from the '-2' quadrature variant.

Programmable Timers And Oscillators Replacement Considerations

Direct functional replacements include other variants within the LTC6908 family, such as the LTC6908IS6-1#TRM for standard industrial temperature ranges. For different package requirements, the DFN versions like LTC6908IDCB-1#TRPBF may be considered if thermal and footprint constraints allow.
