LTC6930HDCB-8.19#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6930HDCB-8.19#TRMPBF is a precision silicon oscillator from the TimerBlox family, featuring a factory-set master frequency of 8.192MHz. It operates on a single 1.7V to 5.5V supply and requires no external components other than bypass capacitors. The device provides an output frequency selectable via three digital DIV pins (DIVA, DIVB, DIVC), allowing division ratios from 1 to 128. This configuration yields frequencies ranging from 32.768kHz to 8.192MHz with a maximum frequency error of less than 0.09% at 25°C. Typical supply current is 500µA at 3V for the base 8.192MHz setting.

Programmable Timers And Oscillators Feature Summary

• Precision silicon oscillator with frequency error <0.09% max at 25°C
• Factory programmed master frequency of 8.192MHz with internal dividers (÷1 to ÷128)
• Ultra-low power consumption: 500µA typical at 3V, 8.192MHz; 190µA typical at 3V, 32.768kHz
• Fast start-up time of typically 110µs with glitch-free output during power-on

Programmable Timers And Oscillators Applications

• Microprocessor clock generation
• Power supply clock monitoring
• Portable and battery-operated devices requiring low power and high accuracy

Programmable Timers And Oscillators Procurement Notes

Verify the specific temperature grade 'H' (-40°C to 125°C) and the 'TRMPBF' tape and reel packaging quantity against project requirements. Confirm that the exposed pad on the DFN package is properly soldered to ground in the design layout to ensure thermal performance and electrical connectivity.

Programmable Timers And Oscillators Selection Notes

Select this part when a fixed master frequency of 8.192MHz is required. Use the DIV pins to achieve lower frequencies down to 32.768kHz. Ensure the operating environment falls within the -40°C to 125°C range specified for the HDCB variant. Consider load capacitance effects on supply current if driving loads significantly larger than 5pF.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930 series of µPower oscillators. The 'H' suffix denotes the industrial/high-temperature grade (-40°C to 125°C). The 'DCB' indicates the 8-lead 2mm x 3mm plastic DFN package. The '#TRMPBF' suffix specifies the lead-free finish and mini-tape and reel packaging format.

Programmable Timers And Oscillators Replacement Considerations

LTC6930IDCB-8.19#TRMPBF offers the same electrical specifications but with a limited temperature range of -40°C to 85°C.
