LTC6990MPS6#TRPBF

Programmable Timers And Oscillators Overview

The LTC6990MPS6#TRPBF is a precision silicon oscillator from the TimerBlox family, manufactured by Analog Devices Inc. It supports programmable frequency ranges from 488Hz to 2MHz and operates as either a fixed-frequency or voltage-controlled oscillator (VCO). The device features a CMOS logic output capable of sourcing and sinking 20mA with a 50% duty cycle square wave. It includes an enable function synchronized with the master oscillator for glitch-free operation. The component is specified for an operating temperature range of –55°C to 125°C and is housed in a 6-lead Plastic TSOT-23 package.

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRPBF indicates Tape and Reel packaging. Confirm the MPS6 designation corresponds to the –55°C to 125°C extended temperature grade. Ensure compatibility with the 6-lead TSOT-23 package dimensions for PCB layout. Check for any automotive-specific reliability reports if required for the target application.

Programmable Timers And Oscillators Selection Notes

Select this part for applications requiring wide temperature stability down to –55°C. Use the TimerBlox design tool to calculate RSET and DIV resistor values for precise frequency settings. Consider the NDIV setting to balance between power consumption and start-up time. Ensure the supply voltage remains within the 2.25V to 5.5V range for optimal performance.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6990 TimerBlox family of versatile silicon timing devices. Other variants include the CS6, IS6, and HS6 packages with different temperature grades. The MPS6 variant specifically offers the widest industrial/automotive temperature range within the TSOT-23 form factor.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements within the same family include other LTC6990 variants with different temperature grades or packages, such as LTC6990HS6#TRPBF for –40°C to 125°C. Verify that the substitute part maintains the required temperature range and package footprint.
