LTC6930CMS8-8.00#PBF

Programmable Timers And Oscillators Overview

The LTC6930CMS8-8.00#PBF 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 8.000000MHz 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 between 105µA at 32kHz and 490µA at 8MHz (at V+ = 3V). Key electrical characteristics include a maximum frequency error of less than 0.09% at 25°C, start-up time under 110µs, and RMS period jitter below 0.15%. It is housed in an 8-lead MSOP package.

Programmable Timers And Oscillators Procurement Notes

Verify the suffix CMS8 indicates the commercial temperature grade (0°C to 70°C) and MSOP package. Confirm the #PBF designation ensures lead-free finish compliance. Cross-reference the specific part marking LTCLD against the datasheet order information table to ensure authenticity and correct factory configuration.

Programmable Timers And Oscillators Selection Notes

Select this variant when a fixed 8MHz base frequency is required with digital divide control. Ensure the application environment stays within the 0°C to 70°C commercial range; otherwise, consider IMS8 or HMS8 variants for wider temperature coverage. Verify that the output load capacitance does not exceed 50pF to maintain specified current and jitter performance.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930 family of µPower Oscillators. The 'CMS8' identifier specifies the Commercial grade (-40°C to 85°C functional, 0°C to 70°C guaranteed), MSOP-8 package, and Lead-Free finish. The '-8.00' denotes the specific 8.000000MHz master oscillator option within the series.

Programmable Timers And Oscillators Replacement Considerations

LTC6930IMS8-8.00#PBF offers the same electrical specifications but with an extended industrial temperature range (-40°C to 85°C). LTC6930HMS8-8.00#PBF provides an extended high-temperature range (-40°C to 125°C). Both are pin-compatible replacements if thermal requirements exceed the commercial grade limits.
