LTC6930IMS8-4.19#TRPBF

Programmable Timers And Oscillators Overview

The LTC6930IMS8-4.19#TRPBF is a precision silicon oscillator from Analog Devices, housed in an 8-lead MSOP package. It operates on a single supply voltage ranging from 1.7V to 5.5V and delivers a master frequency of 4.194304MHz. Internal binary dividers allow the output frequency to be selected between 32.768kHz and 4.194304MHz via three digital control pins (DIVA, DIVB, DIVC). The device features a maximum initial frequency error of 0.09% at 25°C and requires no external components other than bypass capacitors.

Programmable Timers And Oscillators Feature Summary

• Frequency Error <0.09% Max at 25°C
• Start-Up Time <110µs at All Frequencies
• 1.7V to 5.5V Single Supply Operation
• No External Components to Set Frequency

Programmable Timers And Oscillators Applications

• Microprocessor Clock
• Power Supply Clock
• Portable and Battery Operated Devices

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging for the IMS8 variant. Confirm the temperature grade 'I' corresponds to the -40°C to 85°C range required for the application environment. Ensure the ordering information matches the exact master frequency designation for the 4.19 series.

Programmable Timers And Oscillators Selection Notes

Select this part when a fixed master frequency of 4.194304MHz is required with programmable division ratios up to 128. Consider the typical supply current of 260µA at 3V for battery life calculations. Verify that the load capacitance requirements do not exceed the driver's capability without affecting power consumption significantly.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930 family of µPower oscillators. The IMS8 designation specifies the industrial temperature grade (-40°C to 85°C) and the MSOP-8 plastic package. The -4.19 suffix identifies the internal master oscillator frequency as 4.194304MHz, distinguishing it from other variants like -5.00 or -7.37.

Programmable Timers And Oscillators Replacement Considerations

LTC6930CMS8-4.19#TRPBF offers the same electrical specifications but with a commercial temperature range (0°C to 70°C). LTC6930HMS8-4.19#TRPBF provides an extended high-temperature range (-40°C to 125°C). Substitution requires verifying that the ambient operating conditions fall within the replacement part's specified temperature limits.
