LTC6930CDCB-7.37

Programmable Timers And Oscillators Overview

The LTC6930CDCB-7.37 is a precision silicon oscillator from Analog Devices, operating at a fixed frequency of 7.3728MHz. 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.

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'CB-7.37' against the manufacturer's official datasheet to confirm the exact frequency bin and package variant. Ensure compatibility with the target system's voltage requirements (1.7V to 5.5V) and temperature range (-40°C to 85°C or 125°C depending on grade). Confirm RoHS compliance status through the latest product documentation before procurement.

Programmable Timers And Oscillators Selection Notes

Select this part when a fixed, high-precision clock frequency is required without the need for external tuning capacitors or crystals. The LTC6930 series is suitable for applications demanding low power during active operation and rapid wake-up times. Compare the 7.3728MHz option against other available factory-set frequencies (e.g., 32.768kHz, 4.19MHz, 8.192MHz) to determine if alternative divider settings better suit the system timing requirements.

Programmable Timers And Oscillators Part Context

The LTC6930 is part of the TimerBlox family of silicon timing devices by Analog Devices. This series utilizes a proprietary control architecture to achieve industry-leading accuracy and jitter specifications while maintaining ultra-low power consumption. The device integrates a master oscillator and programmable dividers to provide multiple frequency options from a single chip design, eliminating the need for discrete resonant components.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements within the same family include other LTC6930 variants with different fixed frequencies, such as LTC6930IDCB-7.37 or LTC6930CMS8-7.37, provided the package type (DFN vs MSOP) and industrial/commercial temperature grades match the application requirements.
