LTC6930IMS8-7.37#PBF

Programmable Timers And Oscillators Overview

The LTC6930IMS8-7.37#PBF is a precision silicon oscillator from Analog Devices, housed in an 8-lead MSOP package with an industrial temperature range of –40°C to 85°C. It provides a nominal master frequency of 7.3728MHz, which can be divided by integers from 1 to 128 via DIVA, DIVB, and DIVC pins to yield frequencies between 32.768kHz and 8.192MHz. The device operates on a single 1.7V to 5.5V supply, drawing typical currents ranging from 183µA at 3V (÷1) to 453µA at 3V (÷128). Key specifications include a maximum frequency error of 0.09% at 25°C, start-up time under 110µs, and RMS period jitter below 0.15%.

Programmable Timers And Oscillators Procurement Notes

Verify the ordering suffix #PBF indicates lead-free finish and tube packaging. Confirm the IMS8 designation corresponds to the 8-lead plastic MSOP package and the I grade specifies the –40°C to 85°C operating temperature range. Ensure the 7.37 suffix matches the required 7.3728MHz master frequency before procurement.

Programmable Timers And Oscillators Selection Notes

Select this part when a precise 7.3728MHz base frequency is needed with internal division capabilities up to ÷128. Choose the MS8 package for surface-mount applications requiring standard MSOP footprints. Verify that the supply voltage range of 1.7V to 5.5V aligns with the system design and that the industrial temperature range meets environmental requirements.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930 family of µPower oscillators. The IMS8 variant specifically denotes the MSOP package and industrial temperature grade. Other variants include DCB (DFN), CMS8 (Commercial MSOP), and HMS8/MPMS8 (Extended/Military temperature ranges). The 7.37 suffix distinguishes it from other master frequencies like 4.19, 5.00, 8.00, and 8.19 MHz within the same series.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements include other LTC6930 variants with different packages or temperature grades if electrical parameters match. For example, LTC6930CMS8-7.37#PBF offers the same electrical performance in a commercial temperature range. Cross-family substitutes are not explicitly documented in the provided datasheet.
