LTC6930IDCB-4.19#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6930IDCB-4.19#TRMPBF is a precision silicon oscillator from Analog Devices, operating within the –40°C to 85°C temperature range. It provides a nominal master frequency of 4.194304MHz with a maximum initial frequency error of 0.09% at 25°C. The device supports output frequencies ranging from 32.768kHz to 8.192MHz via internal dividers (÷1 to ÷128) controlled by DIVA, DIVB, and DIVC pins. It operates on a single 1.7V to 5.5V supply, drawing typical currents between 105µA at 32kHz and 490µA at 8MHz (V+ = 3V). Key electrical characteristics include a start-up time under 110µs, RMS period jitter below 0.15%, and long-term stability of 30ppm/√kHr.

Programmable Timers And Oscillators Feature Summary

• Precision Frequency Accuracy: Maximum frequency error less than 0.09% at 25°C; drift over temperature is 0.001%/°C for DFN package.
• Low Power Consumption: Typical supply current is 105µA at 32kHz and 490µA at 8MHz with V+ = 3V.
• Fast Start-Up Time: Output stabilizes within 110µs after power application, holding low during initialization to prevent glitches.
• Flexible Frequency Selection: Factory-set master oscillators allow selection of 8 frequencies via digital DIV pins (÷1 to ÷128).

Programmable Timers And Oscillators Applications

• Digitally Controlled Oscillator
• Microprocessor Clock Generation
• Power Supply Clocking
• Portable and Battery Operated Devices

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRMPBF indicates Mini Tape & Reel packaging containing 500 pieces. Confirm the 'I' grade designation matches the required –40°C to 85°C operating temperature range for the target environment. Ensure compatibility with the 8-Lead (2mm × 3mm) Plastic DFN footprint and exposed pad soldering requirements.

Programmable Timers And Oscillators Selection Notes

Select this part when a fixed master frequency of 4.194304MHz is required. Use the DIV pins to achieve desired outputs such as 4.194304MHz (÷1), 2.097152MHz (÷2), or 32.768kHz (÷128). Compare against LTC6930CMS8 variants if industrial temperature range (–40°C to 85°C) is sufficient but MSOP packaging is preferred. Verify load capacitance requirements, as supply current increases significantly with capacitive loading above 5pF.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930-X.XX family of µPower Oscillators. The IDCB suffix denotes the Industrial temperature grade (-40°C to 85°C) and the DCB 8-lead DFN package. The -4.19 suffix specifies the factory-programmed master oscillator frequency of 4.194304MHz. Related parts in the series include variants with different master frequencies (e.g., 5.00, 7.37, 8.00, 8.19 MHz) and packages (MSOP).

Programmable Timers And Oscillators Replacement Considerations

LTC6930IDCB-4.19#TRPBF offers identical electrical specifications and temperature range but utilizes standard Tape & Reel packaging instead of Mini Tape & Reel.
