LTC6995HDCB-1#TRPBF

Programmable Timers And Oscillators Overview

The LTC6995HDCB-1#TRPBF is a silicon oscillator from the TimerBlox family, designed for long duration timing events. It features a programmable period range of 1.024ms to 9.54 hours (29.1µHz to 977Hz). The internal master oscillator frequency is programmed via a single resistor, RSET, connected between the SET and GND pins. The output clock period is determined by this master oscillator and an internal frequency divider, NDIV, which offers eight selectable settings from 1 to 2^21. The device generates a 50% duty cycle square wave output and includes a reset function to stop oscillation and clear dividers. It operates on a single supply voltage ranging from 2.25V to 5.5V.

Programmable Timers And Oscillators Procurement Notes

Verify the component matches the Analog Devices part number LTC6995HDCB-1#TRPBF. Confirm the package is the 6-lead DFN (2mm x 3mm) and the temperature grade is H (-40°C to 125°C). Ensure the suffix #TRPBF indicates tape and reel packaging. Check for authenticity through authorized distributors as supply status may vary.

Programmable Timers And Oscillators Selection Notes

Select the LTC6995-1 version when an active-high reset signal is required; the LTC6995-2 uses active-low. Choose the HDCB package for surface mount applications requiring the DFN form factor. Verify that the operating temperature range of -40°C to 125°C meets system requirements. Use Table 1 in the datasheet to determine the correct resistor values for the DIV pin to set the desired divider ratio and output polarity.

Programmable Timers And Oscillators Part Context

This part belongs to the LTC6995 series within the TimerBlox family of silicon timing devices. The 'H' designation indicates the industrial/high-temperature grade (-40°C to 125°C), while 'DCB' specifies the 6-lead plastic DFN package. The '-1' suffix denotes the LTC6995-1 variant with an active-high reset input. Other variants include the LTC6995-2 with active-low reset and different temperature grades like C or I.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements must match the active-high reset logic of the LTC6995-1. Consider other parts in the TimerBlox family such as the LTC6992 or LTC6993 if different timing functions are needed, but verify pin compatibility and electrical specifications. No direct cross-model substitutes are explicitly listed in the provided documentation.
