LTC6930CDCB-8.19#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6930CDCB-8.19#TRMPBF is a precision silicon oscillator from the TimerBlox family, manufactured by Analog Devices Inc. It operates on a single 1.7V to 5.5V supply and provides a factory-set master frequency of 8.192MHz. The device includes an internal binary divider controlled by three digital inputs (DIVA, DIVB, DIVC), allowing output frequencies ranging from 8.192MHz down to 64kHz. It features a maximum initial frequency error of 0.09% at 25°C and typical RMS period jitter below 0.8ns peak-to-peak. The component is housed in an 8-lead 2mm × 3mm plastic DFN package with an exposed pad.

Programmable Timers And Oscillators Feature Summary

• Factory-programmed 8.192MHz master oscillator with internal divide-by-N capability (N=1 to 128)
• High accuracy with frequency error less than 0.09% maximum at 25°C
• Ultra-low power consumption: typically 500µA at 8.192MHz and 3V supply
• Fast start-up time of approximately 110µs with glitch-free output during initialization

Programmable Timers And Oscillators Applications

• Microprocessor clock generation
• Power supply timing references
• Portable and battery-operated devices requiring low power
• Digitally controlled oscillator applications

Programmable Timers And Oscillators Procurement Notes

Verify that the specified temperature range meets design requirements, as the 'C' grade is guaranteed for operation between 0°C and 70°C. Confirm the package type matches the PCB footprint, specifically noting the requirement to solder the exposed pad (Pin 9) to ground. Ensure the order suffix '#TRMPBF' corresponds to the Mini Tape and Reel packaging format containing 500 pieces.

Programmable Timers And Oscillators Selection Notes

Select this part when a fixed 8.192MHz base frequency is required with programmable division ratios. The CDCB variant is suitable for commercial applications operating within 0°C to 70°C. For wider industrial or military temperature ranges, consider the IDCB (-40°C to 85°C) or HDCB (-40°C to 125°C) variants. Verify that the load capacitance does not exceed 50pF to maintain current specifications.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930 series of µPower oscillators, which offers five master frequency options: 4.194304MHz, 5.000000MHz, 7.372800MHz, 8.000000MHz, and 8.192000MHz. The specific model LTC6930CDCB-8.19 utilizes the 8.192MHz master oscillator option. The series is characterized by its proprietary control architecture that maintains accuracy while minimizing power consumption.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements include other temperature grades of the same frequency, such as LTC6930IDCB-8.19#TRMPBF or LTC6930HDCB-8.19#TRMPBF. Different master frequencies require changing the base model number (e.g., LTC6930CDCB-8.00). MSOP packages like LTC6930CMS8-8.19 are pin-compatible but have different physical dimensions.
