LTC6930CMS8-7.37#TRPBF

Programmable Timers And Oscillators Overview

The LTC6930CMS8-7.37#TRPBF is a precision silicon oscillator from Analog Devices, operating within the 32.768kHz to 8.192MHz range. It features a factory-set master frequency of 7.3728MHz with internal dividers selectable via DIVA, DIVB, and DIVC pins. The device operates on a single 1.7V to 5.5V supply, drawing typical currents of 453µA at 3V for the base frequency. Key specifications include a maximum frequency error of 0.09% at 25°C, start-up time under 110µs, and RMS period jitter below 0.15%. Packaged in an 8-lead MSOP, it requires no external components other than bypass capacitors.

Programmable Timers And Oscillators Procurement Notes

Verify the specific temperature grade 'C' (0°C to 70°C) against application requirements, as other grades like 'I' or 'H' are available. Confirm the package type is MSOP and the suffix '#TRPBF' indicates tape and reel packaging. Ensure the master frequency matches the design need, as custom frequencies require minimum order sizes.

Programmable Timers And Oscillators Selection Notes

Select based on required output frequency derived from the 7.3728MHz master oscillator using the DIV pin settings. Consider power consumption differences across voltage levels; current increases significantly at higher frequencies and voltages. Verify that the load capacitance does not exceed 50pF to maintain stability and manage power dissipation spikes during signal transitions.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930 family of micro-power oscillators. The 'CMS8' designation identifies the commercial temperature grade and MSOP package. The '7.37' indicates the specific master oscillator frequency variant. Other variants in the series include masters at 4.19MHz, 5.00MHz, 8.00MHz, and 8.19MHz.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements within the same family include LTC6930IMS8-7.37#TRPBF (Industrial grade) and LTC6930HMS8-7.37#TRPBF (Extended grade). These share identical electrical characteristics but differ in specified operating temperature ranges.
