LTC6930CDCB-8.00

Programmable Timers And Oscillators Overview

The LTC6930CDCB-8.00 is a precision silicon oscillator from Analog Devices, operating at a fixed frequency of 8.00 MHz. It functions as a low-power clock source requiring no external components for frequency setting, relying solely on internal dividers derived from a master oscillator. The device supports single-supply operation within a voltage range of 1.7V to 5.5V. Key electrical characteristics include a maximum frequency error of less than 0.09% at 25°C and a typical supply current of 490µA at 8MHz with a 3V supply. It features an exceptionally fast start-up time of under 110µs and typical RMS period jitter below 0.15%. The component is housed in an 8-pin DFN package with an exposed pad.

Programmable Timers And Oscillators Feature Summary

• Fixed 8.00 MHz output frequency with <0.09% max frequency error at 25°C

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix codes against official Analog Devices documentation to confirm package type, temperature range, and tape/reel specifications. Ensure compatibility with the target PCB footprint for the 8-DFN EP package. Cross-reference part numbers with authorized distributors to confirm availability and authenticity.

Programmable Timers And Oscillators Selection Notes

Select this model when a fixed 8.00 MHz clock is required without external tuning components. Consider the 1.7V to 5.5V supply range for compatibility with Li-Ion or alkaline cell systems. Evaluate the 490µA current draw at 8MHz against system power budgets. Verify that the <0.09% accuracy meets the timing requirements of the downstream digital logic.

Programmable Timers And Oscillators Part Context

The LTC6930 series comprises precision µPower oscillators offering multiple frequency options between 32.768kHz and 8.192MHz. The CDCB variant denotes the commercial temperature range (-40°C to 85°C) and DFN packaging. This family utilizes a proprietary control architecture to maintain industry-leading accuracy and jitter specifications while minimizing power consumption.

Programmable Timers And Oscillators Replacement Considerations

Direct substitutes within the same family include other LTC6930 variants with different fixed frequencies (e.g., LTC6930CDCB-4.19, LTC6930CDCB-7.37). For different packages, check the IMS8 (MSOP) variants such as LTC6930IMS8-8.00. Ensure any replacement matches the 8.00 MHz frequency and 8-DFN pinout.
