LTC6930CMS8-4.19#PBF

Programmable Timers And Oscillators Overview

The LTC6930CMS8-4.19#PBF is a precision silicon oscillator from the LTC6930 series, housed in an 8-lead plastic MSOP package. It operates on a single 1.7V to 5.5V supply and provides a base master frequency of 4.194304MHz. Internal binary dividers ranging from 1 to 128 allow output frequencies between 32.768kHz and 8.192MHz. The device features a maximum frequency error of less than 0.09% at 25°C and typical RMS period jitter below 0.15%. Supply current ranges from 105µA at 32kHz to 490µA at 8MHz with a 3V supply. It requires no external components for frequency setting other than bypass capacitors.

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #PBF indicates lead-free finish and tube packaging for the MS8 variant. Confirm the operating temperature range corresponds to the 'C' grade, which is specified from 0°C to 70°C. Ensure the order information matches the requested base frequency of 4.194304MHz.

Programmable Timers And Oscillators Selection Notes

Select this part when a fixed master frequency of 4.194304MHz is required. Use DIV pins to achieve target frequencies via division by 1, 2, 4, 8, 16, 32, 64, or 128. Choose the CMS8 package for surface mount applications requiring the commercial temperature range. Consider power consumption implications if driving heavy capacitive loads.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930 family of µPower Oscillators. The 'CMS8' designation identifies the Commercial temperature grade (-40°C to 85°C functional, 0°C to 70°C guaranteed) and the 8-lead MSOP package. The '-4.19' suffix specifies the factory-programmed master oscillator frequency of 4.194304MHz.
