LTC6990HS6#WTRPBF

Programmable Timers And Oscillators Overview

The LTC6990HS6#WTRPBF is an automotive-grade precision silicon oscillator from the TimerBlox family, manufactured by Analog Devices Inc. It operates as a fixed-frequency or voltage-controlled oscillator (VCO) with a programmable frequency range of 488Hz to 2MHz. The device features a CMOS logic output capable of sourcing and sinking 20mA. Frequency is programmed via a single resistor at the SET pin and an internal divider (NDIV) selectable from 1 to 128 through the DIV pin. It includes an enable function for glitch-free operation and is specified for temperatures ranging from -40°C to 125°C.

Programmable Timers And Oscillators Feature Summary

• Automotive qualified (AEC-Q100) with extended temperature range (-40°C to 125°C)
• Programmable frequency range from 488Hz to 2MHz using a single resistor
• CMOS output sources/sinks 20mA with selectable low or high-impedance disable states
• Voltage-controlled operation capability with linear frequency modulation

Programmable Timers And Oscillators Applications

• Voltage-Controlled Oscillator circuits
• Replacement for fixed crystal and ceramic oscillators in high vibration environments
• Portable and battery-powered equipment requiring low power consumption

Programmable Timers And Oscillators Procurement Notes

Verify that the #W suffix indicates automotive grade qualification. Confirm the S6 package designation corresponds to the 6-lead plastic TSOT-23 form factor. Ensure the HS6 temperature grade matches the required -40°C to 125°C operating range for the specific application environment.

Programmable Timers And Oscillators Selection Notes

Select this part when automotive reliability and wide temperature operation are required. Choose between fixed-frequency or VCO modes based on whether a second resistor is added to the SET pin. Use Table 1 in the datasheet to determine the correct resistor values for the desired NDIV setting and Hi-Z behavior upon disable.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6990 TimerBlox family of versatile silicon timing devices. The HS6 variant specifically denotes the high-temperature grade housed in the S6 (TSOT-23) package. The #W suffix identifies it as an automotive product with controlled manufacturing processes.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements within the same family include LTC6990IS6#WTRMPBF for commercial temperature grades. Non-automotive equivalents like LTC6990HS6#TRMPBF lack the #W automotive qualification suffix.
