LTC6930HMS8-8.19#TRPBF

Programmable Timers And Oscillators Overview

The LTC6930HMS8-8.19#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 8.192MHz with an initial accuracy of less than 0.09% at 25°C. The device supports output frequencies ranging from 32.768kHz to 8.192MHz via internal dividers (÷1 to ÷128) controlled by DIVA, DIVB, and DIVC pins. It operates on a single 1.7V to 5.5V supply, consuming typically 500µA at 3V for the base frequency. Key electrical characteristics include a start-up time under 110µs, typical RMS period jitter below 0.15%, and long-term stability of 30ppm/√kHr.

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm the 'H' grade designation matches the required –40°C to 125°C operating temperature range for your application environment. Ensure compatibility with the 8-lead MSOP package dimensions during PCB layout planning.

Programmable Timers And Oscillators Selection Notes

Select the LTC6930HMS8-8.19 variant specifically for applications requiring an 8.192MHz master frequency. Choose the 'H' industrial grade over 'C' or 'I' grades if the system must function reliably up to 125°C. Consider the load capacitance requirements, as supply current increases significantly with higher capacitive loads on the OUT pin.

Programmable Timers And Oscillators Part Context

This part belongs to the LTC6930 family of µPower oscillators, which includes variants with different master frequencies such as 4.19MHz, 5.00MHz, 7.37MHz, and 8.00MHz. The 'HMS8' designation identifies the high-temperature grade housed in an 8-lead MSOP package. The '#TRPBF' suffix denotes lead-free finish and tape and reel shipping configuration.

Programmable Timers And Oscillators Replacement Considerations

Other members of the LTC6930 family, such as the LTC6930IMS8-8.19#TRPBF or LTC6930CMS8-8.19#TRPBF, share identical pinouts and electrical functions but differ in specified operating temperature ranges.
