LTC6930MPMS8-7.37#TRPBF

Programmable Timers And Oscillators Overview

The LTC6930MPMS8-7.37#TRPBF is a precision silicon oscillator from Analog Devices, operating within the –55°C to 125°C temperature range. It features a factory-set master frequency of 7.3728MHz with an initial accuracy of ±0.09% at 25°C and ±1.3% across the full voltage and temperature range. The device operates on a single 1.7V to 5.5V supply, drawing typical currents of 453µA at 3V for divide-by-1 and 183µA for divide-by-2. It utilizes internal dividers (1 to 128) selectable via DIV pins, requires no external tuning components, and exhibits typical RMS period jitter below 0.15%.

Programmable Timers And Oscillators Procurement Notes

Verify the MP grade suffix indicates the extended –55°C to 125°C industrial/military temperature range compared to standard C or I grades. Confirm the MS8 package type matches the PCB footprint requirements. Ensure the #TRPBF designation corresponds to the tape and reel packaging format required for automated assembly processes.

Programmable Timers And Oscillators Selection Notes

Select this part when extreme temperature stability is required, as it covers –55°C to 125°C unlike the C (-40°C to 85°C) or I (-40°C to 85°C) variants. Choose the 7.37 suffix if the base frequency of 7.3728MHz aligns with standard baud rate divisors. Verify that the required output frequency can be achieved using the available integer dividers (1, 2, 4, 8, 16, 32, 64, 128) listed in Table 1 of the datasheet.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930 family of µPower oscillators. The 'MP' suffix specifically denotes the military/extended temperature grade variant, distinguishing it from the commercial (C) and industrial (I) versions which have narrower operating ranges. The 'MS8' indicates the 8-lead plastic MSOP package, while '7.37' specifies the 7.3728MHz master oscillator frequency.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements include other LTC6930MPMS8 variants with different frequency suffixes (e.g., -4.19, -5.00, -8.00, -8.19) if the specific 7.3728MHz base frequency is not critical. Lower-grade temperature variants like LTC6930IMS8-7.37#TRPBF may be used if the application does not require operation below –40°C.
