LTC6930HMS8-4.19#TRPBF

Programmable Timers And Oscillators Overview

The LTC6930HMS8-4.19#TRPBF is a precision silicon oscillator from Analog Devices, operating within the –40°C to 125°C temperature range. It provides a nominal master frequency of 4.194304MHz with a maximum initial frequency error of 0.09% at 25°C. The device supports output frequencies ranging from 32.768kHz to 8.192MHz via internal dividers controlled by DIVA, DIVB, and DIVC pins. It operates on a single 1.7V to 5.5V supply, consuming typical currents between 105µA at 32kHz and 490µA at 8MHz (at 3V). Key electrical characteristics include a start-up time under 110µs, RMS period jitter below 0.15%, and long-term stability of 30ppm/√kHr.

Programmable Timers And Oscillators Feature Summary

• Precision Frequency Accuracy: Maximum frequency error less than 0.09% at 25°C; drift over temperature is 0.0001%/°C for MS8 package.
• Low Power Consumption: Typical supply current is 105µA at 32kHz and 490µA at 8MHz when powered by 3V.
• Fast Start-Up Time: Output becomes stable in less than 110µs after power application, suitable for battery-operated devices.
• Flexible Frequency Selection: Internal binary divider allows selection of 8 frequencies from 32.768kHz to 8.192MHz based on the 4.194304MHz master oscillator.

Programmable Timers And Oscillators Applications

• Digitally Controlled Oscillator
• Microprocessor Clock Generation
• Power Supply Clocking
• Portable and Battery Operated Devices

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRPBF indicates Tape and Reel packaging with lead-free finish. Confirm the 'H' grade ensures operation up to 125°C. Check that the 'MS8' designation matches the required 8-lead Plastic MSOP package footprint. Ensure the ordering quantity aligns with standard reel specifications if bulk quantities are needed.

Programmable Timers And Oscillators Selection Notes

Select this part when an extended industrial temperature range (-40°C to 125°C) is required, as indicated by the 'H' suffix. Choose the -4.19 variant specifically for applications needing a 4.194304MHz base frequency. Compare against 'I' grade parts if only commercial temperatures (-40°C to 85°C) are sufficient. Verify that the 8-lead MSOP package fits the PCB layout constraints compared to the DFN option.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930 series of µPower oscillators. The 'H' suffix denotes the high-temperature industrial grade (-40°C to 125°C), while 'MS8' specifies the 8-lead Mini-Small Outline Package. The '-4.19' indicates the factory-set master oscillator frequency of 4.194304MHz. The '#TRPBF' suffix confirms it is supplied in a tape and reel format with lead-free plating.

Programmable Timers And Oscillators Replacement Considerations

LTC6930IMS8-4.19#TRPBF offers identical electrical performance but is rated for the commercial temperature range (-40°C to 85°C). LTC6930HDCB-4.19#TRPBF provides the same temperature rating but uses an 8-lead DFN package instead of MSOP. Other frequency variants like LTC6930HMS8-8.19#TRPBF share the package and grade but have different master frequencies.
