LTC6930IDCB-8.19#TRPBF

Programmable Timers And Oscillators Overview

The LTC6930IDCB-8.19#TRPBF is a precision silicon oscillator from the TimerBlox family, manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 1.7V to 5.5V and requires no external components other than power supply bypass capacitors. The device features a factory-set master frequency of 8.192MHz with an initial frequency accuracy better than 0.09% at 25°C. Internal dividers allow output frequencies from 32.768kHz to 8.192MHz. Typical supply current is 500µA at 3V for the full 8.192MHz output. It utilizes an 8-lead (2mm × 3mm) plastic DFN package.

Programmable Timers And Oscillators Feature Summary

• Frequency error less than 0.09% maximum at 25°C
• Start-up time typically under 110µs at all frequencies
• Single 1.7V to 5.5V supply operation
• Typical RMS period jitter less than 0.8ns peak-to-peak at 3V

Programmable Timers And Oscillators Applications

• Digitally controlled oscillators
• Microprocessor clock generation
• Power supply clocking
• Portable and battery-operated devices

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm the 'I' grade designation matches the required operating temperature range of –40°C to 85°C for your application environment. Ensure compatibility with the 8-lead DFN footprint during procurement planning.

Programmable Timers And Oscillators Selection Notes

Select the LTC6930IDCB-8.19 variant specifically when a base master frequency of 8.192MHz is required. Use the DIV pins to achieve lower frequencies via integer division up to 128. Consider the 500µA typical current draw at 3V for battery life calculations. Verify that the load capacitance requirements align with the specified 5pF test conditions for accurate jitter performance.

Programmable Timers And Oscillators Part Context

This part belongs to the LTC6930 series of micropower oscillators. The IDCB suffix denotes the industrial temperature grade (-40°C to 85°C) and the 8-lead DFN package. The 8.199 number specifies the internal master oscillator frequency. Other variants in the series include 4.19, 5.00, 7.37, and 8.00 MHz masters.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements within the same family include LTC6930IDCB-4.19#TRPBF, LTC6930IDCB-5.00#TRPBF, LTC6930IDCB-7.37#TRPBF, and LTC6930IDCB-8.00#TRPBF. These share identical pinouts and electrical characteristics except for the factory-set master frequency.
