LTC6930IMS8-8.19#TRPBF

Programmable Timers And Oscillators Overview

The LTC6930IMS8-8.19#TRPBF is a precision silicon oscillator from Analog Devices Inc., housed in an 8-lead MSOP package. It provides a nominal master frequency of 8.192MHz with a maximum initial frequency error of 0.09% at 25°C. The device operates on a single supply voltage ranging from 1.7V to 5.5V and draws typical supply currents between 190µA and 500µA depending on the load and voltage level. It features a fast start-up time of less than 110µs and supports output frequencies from 64kHz to 8.192MHz via internal binary dividers controlled by three digital pins.

Programmable Timers And Oscillators Feature Summary

• Precision silicon oscillator with frequency error less than 0.09% at 25°C

• Single 1.7V to 5.5V supply operation suitable for battery-powered devices
• Internal frequency divider allows selection of 8 frequencies from 64kHz to 8.192MHz

Programmable Timers And Oscillators Applications

• Digitally controlled oscillators
• Microprocessor clock generation
• Power supply clock sources
• Portable and battery-operated devices

Programmable Timers And Oscillators Procurement Notes

Verify that the component matches the specified 8.192MHz master frequency variant. Confirm the ordering suffix #TRPBF indicates tape and reel packaging, which differs from tube packaging for other variants. Ensure the IMS8 designation corresponds to the industrial temperature range of –40°C to 85°C rather than commercial or extended ranges.

Programmable Timers And Oscillators Selection Notes

Select this part when a fixed 8.192MHz base frequency is required. Use the DIVA, DIVB, and DIVC pins to configure the output divider ratio between 1 and 128. Consider the supply current increase associated with higher capacitive loads on the OUT pin, as driving larger capacitances significantly increases power dissipation compared to the standard 5pF specification.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930 family of µPower oscillators. The IMS8 suffix identifies the industrial temperature grade (–40°C to 85°C) and the MSOP-8 plastic package. Other variants in the series include different master frequencies such as 4.19MHz, 5.00MHz, 7.37MHz, and 8.00MHz, available in DFN or MSOP packages with varying temperature grades.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements within the same family require matching the master frequency suffix (e.g., LTC6930IMS8-8.00#TRPBF for 8.00MHz). Verify that the substitute part shares the MSOP-8 package and industrial temperature rating to ensure mechanical and thermal compatibility.
