LTC6990HS6#WTRMPBF

Programmable Timers And Oscillators Overview

The LTC6990HS6#WTRMPBF is an automotive-grade precision silicon oscillator from the TimerBlox family, manufactured by Analog Devices Inc. It operates within a programmable frequency range of 488Hz to 2MHz and supports both fixed-frequency and voltage-controlled oscillator (VCO) modes. The device features a CMOS logic output capable of sourcing or sinking 20mA with a 50% duty cycle square wave. Key electrical parameters include a supply voltage range of 2.25V to 5.5V, a typical supply current of 137µA at 5.5V with NDIV=128, and a frequency accuracy of ±1.5% over the recommended resistor range. It is housed in a 6-lead Plastic TSOT-23 package.

Programmable Timers And Oscillators Feature Summary

• Automotive qualified (AEC-Q100) with specified temperature range of –40°C to 125°C
• Programmable frequency divider (NDIV) with eight settings from 1 to 128 via DIV pin
• Voltage-controlled operation using SET pin current for linear frequency modulation
• Output enable function with selectable low or high-impedance disabled states

Programmable Timers And Oscillators Applications

• Voltage-controlled oscillators requiring wide tuning ranges
• Replacement for fixed crystal and ceramic oscillators in portable equipment
• High vibration and high acceleration environments
• Battery-powered devices requiring low power consumption

Programmable Timers And Oscillators Procurement Notes

Verify that the #W suffix confirms AEC-Q100 qualification for automotive applications. Confirm the HS6 designation corresponds to the –40°C to 125°C operating temperature range and the S6 package type. Ensure the TRMPBF suffix indicates tape and reel packaging with lead-free finish. Cross-reference the specific lot traceability requirements if mandated by the target automotive assembly process.

Programmable Timers And Oscillators Selection Notes

Select this variant when automotive reliability standards are required alongside extended industrial temperature performance. The HS6 grade guarantees performance from –40°C to 125°C, distinguishing it from the CS6 (commercial) and IS6 (industrial) grades. Choose based on the need for the TSOT-23 package form factor. Verify that the internal master oscillator frequency and divider settings meet the specific timing jitter and settling time constraints of the system design.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6990 TimerBlox family of versatile silicon timing devices. It serves as a low-cost, precision programmable oscillator alternative to traditional discrete timing circuits. The HS6#WTRMPBF specifically denotes the high-temperature, automotive-qualified version in a mini-reel tape and reel format, designed for automated surface-mount assembly processes.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements within the same family include LTC6990IS6#WTRMPBF for standard industrial temperature ranges or LTC6990MPS6#TRMPBF for military-grade specifications. Non-automotive equivalents such as LTC6990HS6#TRMPBF lack the controlled manufacturing for automotive use. Ensure substitute parts match the 6-lead TSOT-23 package and voltage/current drive capabilities.
