LTC6995CDCB-2#TRPBF

Programmable Timers And Oscillators Overview

The LTC6995CDCB-2#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 output clock period is determined by an internal master oscillator and a programmable frequency divider (NDIV) with eight settings from 1 to 221. A single resistor, RSET, programs the internal master oscillator frequency. The device includes a reset function to stop the oscillator and clear dividers, with active-low reset polarity specific to the -2 version. It operates on a single supply voltage of 2.25V to 5.5V.

Programmable Timers And Oscillators Procurement Notes

Verify the specified temperature range of 0°C to 70°C for the 'C' grade against application requirements. Confirm the DCB package (6-Lead 2mm x 3mm Plastic DFN) compatibility with PCB layout constraints. Ensure the #TRPBF suffix indicates tape and reel packaging suitable for automated assembly processes.

Programmable Timers And Oscillators Selection Notes

Select the LTC6995-2 variant when an active-low reset signal is required. Use Table 1 in the datasheet to determine the correct resistor divider values for the DIV pin to set the desired NDIV and output polarity. Calculate RSET based on the target frequency, ensuring the resistor tolerance and temperature coefficient meet the required accuracy specifications.
