LTC6905CS5-80#TRMPBF

Programmable Timers And Oscillators Overview

The Analog Devices LTC6905CS5-80#TRMPBF is a fixed-frequency silicon oscillator in a 5-lead ThinSOT package. It provides three output frequencies: 80MHz, 40MHz, and 20MHz, selected via the DIV pin. The device operates on a single 2.7V to 5.5V supply with typical current consumption of 11mA at 80MHz (÷1). Key specifications include ±0.5% frequency accuracy at 25°C, ±20ppm/°C temperature stability, and <0.8% timing jitter. It features an Output Enable (OE) pin for synchronous control and CMOS outputs capable of driving loads up to 600Ω.

Programmable Timers And Oscillators Feature Summary

• Factory-programmed fixed frequencies: 80MHz, 40MHz, and 20MHz
• High frequency accuracy: ±0.5% typical at 25°C
• Low temperature drift: ±20ppm/°C
• Fast start-up time: 100µs typical

Programmable Timers And Oscillators Applications

• Data clocks for high reliability applications
• Replacement for fixed crystal and ceramic oscillators
• High vibration and high acceleration environments

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRMPBF against official documentation to confirm tape and reel packaging and lead-free status. Ensure the 'C' grade designation matches the required operating temperature range of 0°C to 70°C for the application environment.

Programmable Timers And Oscillators Selection Notes

Select this part when board space is limited and no external trim components are desired. Choose the LTC6905CS5-80 variant specifically for 80MHz master clock requirements. Consider the LTC6905IS5-80 if operation below 0°C is required, as the 'C' grade is specified for 0°C to 70°C.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6905-XXX series of precision fixed-frequency silicon oscillators. The family includes variants for 133MHz, 100MHz, 96MHz, and 80MHz master clocks. All share the same 5-lead ThinSOT package and functional architecture, differing primarily in factory-set frequency and temperature grade.
