LTC6930CMS8-8.00#TRPBF

Programmable Timers And Oscillators Overview

The LTC6930CMS8-8.00#TRPBF is a precision silicon oscillator operating from a single 1.7V to 5.5V supply. It provides an 8MHz nominal master frequency with internal dividers ranging from 1 to 128, selectable via DIVA, DIVB, and DIVC pins. The device features a frequency error of less than 0.09% at 25°C and typical RMS period jitter under 0.15%. Supply current ranges from 105µA at 32kHz to 490µA at 8MHz (V+ = 3V). It operates within a commercial temperature range of 0°C to 70°C and utilizes an 8-lead MSOP package.

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging for the MSOP variant. Confirm the 'C' grade corresponds to the 0°C to 70°C operating range required for the application environment. Ensure the ordering part number matches the exact frequency division requirements derived from the 8MHz master oscillator.

Programmable Timers And Oscillators Selection Notes

Select this component when a fixed 8MHz master source with programmable division is needed. The CMS8 package limits operation to 0°C to 70°C; use IMS8 or HMS8 variants for wider industrial or extended temperature ranges. Verify that the load capacitance on the OUT pin does not exceed specifications to maintain current and jitter performance.

Programmable Timers And Oscillators Part Context

This part belongs to the LTC6930 family of micropower oscillators. The '8.00' designation specifies an 8MHz master frequency. The 'CMS8' indicates the commercial temperature grade and MSOP package. The '#TRPBF' suffix denotes lead-free finish and tape and reel shipping format.

Programmable Timers And Oscillators FAQ

How is the output frequency determined?

The output frequency is the master frequency (8MHz) divided by an integer from 1 to 128. The divider value is set by the logic states of the DIVA, DIVB, and DIVC pins.

What is the maximum capacitive load supported?

The device can drive up to 50pF capacitive load. Exceeding this may increase supply current significantly and affect performance.

Does the output have glitches during startup?

No. The output is held low for approximately 50µs after power-on to prevent glitches, runt pulses, or invalid frequencies before the oscillator stabilizes.
