LTC6930HMS8-4.19#PBF

Programmable Timers And Oscillators Overview

The LTC6930HMS8-4.19#PBF is a precision silicon oscillator from Analog Devices, operating within a 1.7V to 5.5V single supply range. It provides a nominal master frequency of 4.194304MHz with a maximum frequency error of less than 0.09% at 25°C. The device features an internal binary divider controlled by DIVA, DIVB, and DIVC pins, allowing output frequencies ranging from 32.768kHz to 8.192MHz. Typical supply current is 105µA at 32kHz and 490µA at 8MHz when powered at 3V. It operates in the –40°C to 125°C temperature range and utilizes an 8-lead MSOP package.

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'H' indicates the extended industrial temperature range of –40°C to 125°C. Confirm the 'MS8' designation corresponds to the 8-lead plastic MSOP package. Ensure the '#PBF' suffix denotes lead-free finish compliance. Cross-reference the base model number with official manufacturer documentation to confirm availability and exact electrical specifications for this grade.

Programmable Timers And Oscillators Selection Notes

Select this component when a fixed master frequency of 4.194304MHz is required with programmable division ratios up to 128. The H-grade variant is necessary for applications requiring operation up to 125°C. Consider the typical supply current variations based on the selected divide ratio and supply voltage. Ensure the load capacitance requirements are met, as the specified performance assumes a 5pF load.

Programmable Timers And Oscillators Part Context

This part belongs to the LTC6930 series of precision µPower oscillators. The family includes variants with different master frequencies (4.19MHz, 5.00MHz, 7.37MHz, 8.00MHz, 8.19MHz) and temperature grades (C, I, H, MP). The MS8 package offers a compact footprint suitable for space-constrained designs. The device integrates a master oscillator and control loop without external tuning components.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements within the same family include LTC6930IMS8-4.19#PBF for commercial/industrial temperature ranges or LTC6930CMS8-4.19#PBF for commercial use. For different master frequencies, consider LTC6930HMS8-5.00#PBF or LTC6930HMS8-8.19#PBF. Verify pin compatibility and thermal characteristics when substituting.
