LTC6905HS5-100#TRPBF

Programmable Timers And Oscillators Overview

The LTC6905HS5-100#TRPBF is a precision, fixed-frequency silicon oscillator from Analog Devices Inc., designed to minimize board space while maximizing accuracy. It operates with a single supply voltage ranging from 2.7V to 5.5V and provides a rail-to-rail CMOS output. The device features a typical frequency error of ±0.5% at 25°C and a temperature stability of ±20ppm/°C. Key electrical parameters include a typical power supply current of 8mA at 100MHz, a rise time of 0.5ns with a 5pF load, and timing jitter of less than 0.8%. The unit is housed in a low-profile 1mm ThinSOT package.

Programmable Timers And Oscillators Feature Summary

• Factory-programmed fixed frequency of 100MHz with no external components required for setting.
• Internal three-state divider allows selection of master clock division by 1, 2, or 4.
• Includes an Output Enable (OE) pin that synchronously enables the output to avoid pulse slivers.
• CMOS output drives loads up to 600Ω with a typical duty cycle of 50% ±2.5%.

Programmable Timers And Oscillators Applications

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

Programmable Timers And Oscillators Procurement Notes

Verify the suffix #TRPBF indicates Lead Free Tape and Reel packaging. Confirm the HS5 designation corresponds to the -40°C to 125°C operating temperature range. Ensure the specific part number matches the required 100MHz frequency setting before procurement.

Programmable Timers And Oscillators Selection Notes

Select this model for applications requiring a 100MHz fixed frequency source in harsh thermal environments up to 125°C. Consider the internal divider options if lower frequencies (50MHz or 25MHz) are needed without changing the component. Ensure the power supply noise does not contain content at fMO/64 (1.5625MHz) to maintain frequency accuracy.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6905-XXX series of fixed frequency silicon oscillators. Other variants in the family include the LTC6905-133, LTC6905-96, and LTC6905-80, which offer different base frequencies. The 'H' grade specifically denotes the extended industrial/high-temperature performance range compared to the 'C' and 'I' grades.
