LTC6930HDCB-4.19#TRPBF

Programmable Timers And Oscillators Overview

The LTC6930HDCB-4.19#TRPBF is a precision micro-power silicon oscillator from Analog Devices, operating within a –40°C to 125°C temperature range. It features a factory-set master frequency of 4.194304MHz with an initial accuracy of ±0.09% at 25°C. The device supports eight selectable output frequencies via three digital DIV pins (DIVA, DIVB, DIVC), ranging from 32.768kHz to 4.194304MHz using integer dividers from 1 to 128. Powered by a single 1.7V to 5.5V supply, it consumes as little as 80µA at 32kHz and 490µA at 4.19MHz. Packaged in an 8-lead 2mm × 3mm DFN, it requires no external components for frequency setting.

Programmable Timers And Oscillators Feature Summary

• Frequency error less than 0.09% maximum at 25°C
• Fast start-up time under 110µs at all frequencies
• Single 1.7V to 5.5V supply operation
• Typical RMS period jitter less than 0.15% at V+ = 3V

Programmable Timers And Oscillators Applications

• Digitally controlled oscillators
• Microprocessor clock generation
• Power supply clocks
• 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 that the H grade meets the required –40°C to 125°C operating temperature range for your application environment. Ensure the DCB package dimensions align with your PCB footprint requirements.

Programmable Timers And Oscillators Selection Notes

Select the LTC6930HDCB-4.19 variant if a base master frequency of 4.194304MHz is required. Use the DIV pins to achieve lower frequencies such as 32.768kHz or 2.097152MHz. Choose the H grade over C or I grades only if the application demands operation up to 125°C. Consider the 80Ω typical series resistance at 1.7V when designing output loading.

Programmable Timers And Oscillators Part Context

This part belongs to the LTC6930 family of precision µPower Oscillators. The 'H' designation specifies the extended industrial temperature range of –40°C to 125°C. The 'DCB' indicates the 8-lead plastic DFN package format. The '#TRPBF' suffix denotes lead-free finish and tape and reel shipping configuration.

Programmable Timers And Oscillators Replacement Considerations

For equivalent performance in the same package, consider the LTC6930IDCB-4.19#TRPBF for standard industrial temperatures or the LTC6930CDCB-4.19#TRPBF for commercial temperatures. For MSOP packages, the LTC6930HMS8-4.19#TRPBF offers identical electrical characteristics.
