LTC6930CDCB-8.19#TRPBF

Programmable Timers And Oscillators Overview

The LTC6930CDCB-8.19#TRPBF is a precision silicon oscillator from Analog Devices, operating within the 32.768kHz to 8.192MHz range. It features a factory-set master frequency of 8.192MHz with internal dividers selectable via DIVA, DIVB, and DIVC pins. The device supports single-supply operation from 1.7V to 5.5V, drawing typical currents between 105µA at 32kHz and 500µA at 8.192MHz (V+ = 3V). Key specifications include a maximum frequency error of 0.09% at 25°C, start-up time under 110µs, and RMS period jitter below 0.15%. It utilizes an 8-lead 2mm × 3mm DFN package.

Programmable Timers And Oscillators Procurement Notes

Verify the specific temperature grade 'C' for commercial applications (0°C to 70°C) against system requirements. Confirm the tape and reel packaging format matches automated assembly needs. Ensure the exposed pad on the DFN package is properly soldered to ground for thermal and electrical performance.

Programmable Timers And Oscillators Selection Notes

Select this part when a fixed 8.192MHz master frequency with programmable division is required. Choose based on the necessary output frequency derived from Table 1 in the datasheet using DIV pin states. Consider the -40°C to 85°C 'I' grade or -40°C to 125°C 'H' grade if operating outside the commercial range.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930 family of µPower Oscillators. The 'CDCB' suffix indicates the Commercial temperature grade (-40°C to 85°C functional, 0°C to 70°C specified) and the DCB 8-lead DFN package. The '#TRPBF' suffix denotes lead-free finish and tape and reel packaging.
