LTC6930MPMS8-8.00#PBF

Programmable Timers And Oscillators Overview

The LTC6930MPMS8-8.00#PBF is a precision silicon oscillator from Analog Devices, operating within the –55°C to 125°C temperature range. It provides a factory-set master frequency of 8.000000MHz with an initial accuracy of ±0.09% at 25°C. The device features internal dividers (÷1 to ÷128) selectable via DIVA, DIVB, and DIVC pins, enabling output frequencies from 62.5kHz to 8MHz. Supply voltage ranges from 1.7V to 5.5V, with typical current consumption of 491µA at 3V for the ÷1 setting. It utilizes an 8-lead MSOP package.

Programmable Timers And Oscillators Feature Summary

• Factory-programmed 8.00MHz master oscillator with <0.09% frequency error at 25°C
• Internal binary divider allows selection of 8 frequencies from 62.5kHz to 8MHz
• Ultra-low power operation: 198µA typical at 3V, ÷1; 491µA typical at 3V, ÷1 (max freq)
• Fast start-up time of typically 110µs with glitch-free output during power-on

Programmable Timers And Oscillators Applications

• Digitally controlled oscillators requiring precise frequency stability
• Microprocessor clock generation in harsh environments
• Power supply clocking for battery-operated portable devices
• Systems requiring frequent power-up cycles with low standby current

Programmable Timers And Oscillators Procurement Notes

Verify the MP grade designation confirms the extended –55°C to 125°C operating range required for the application. Ensure the MS8 package type matches the PCB footprint constraints. Confirm that the fixed 8.00MHz master frequency aligns with the desired divided outputs listed in Table 1 of the datasheet.

Programmable Timers And Oscillators Selection Notes

Select this part when a fixed 8MHz base frequency is needed with programmable division ratios up to ÷128. Compare supply current requirements against load capacitance, as current increases significantly with higher capacitive loads. Consider the DCB DFN package if a smaller 2mm x 3mm footprint is preferred over the MSOP form factor.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930 series of µPower oscillators. The 'MP' suffix indicates the military/extended temperature grade (-55°C to 125°C), while 'MS8' denotes the 8-lead plastic MSOP package. The '-8.00' specifies the 8.000000MHz master oscillator frequency option.

Programmable Timers And Oscillators Replacement Considerations

LTC6930IMS8-8.00#PBF offers identical electrical specifications but operates within the industrial temperature range of –40°C to 85°C instead of the extended MP range.
