LTC6930IDCB-7.37

Programmable Timers And Oscillators Overview

The LTC6930IDCB-7.37 is a precision silicon oscillator from Analog Devices Inc., designed for low-power applications. It operates on a single supply voltage ranging from 1.7V to 5.5V, enabling functionality with minimal external components, limited to power supply bypass capacitors. The device provides a fixed output frequency of 7.3728MHz, selected via internal dividers from a master clock. Key electrical characteristics include a maximum frequency error of less than 0.09% at 25°C and a typical RMS period jitter of under 0.15% at 3V. Supply current varies by frequency, typically measuring 105µA at 32kHz and 490µA at 8MHz when powered at 3V.

Programmable Timers And Oscillators Feature Summary

• Portable and battery-operated devices

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930 series of TimerBlox precision micro-power oscillators. The 'I' suffix indicates an industrial temperature range (-40°C to +125°C), while 'DCB' denotes the 8-pin DFN EP package. The '-7.37' specifies the factory-set output frequency of 7.3728MHz. Variants such as LTC6930IDCB-7.37#TRMPBF or #TRPBF indicate different tape-and-reel packaging options for the same functional device.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements within the same family include other LTC6930 variants with different frequency codes (e.g., -4.19, -5.00, -8.00) or package types (e.g., CMS8). Ensure the substitute matches the required output frequency and operating temperature range. Packaging differences between tube (#PBF) and tape-and-reel (#TRMPBF/#TRPBF) do not alter electrical performance.
