LTC6930CDCB-5.00#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6930CDCB-5.00#TRMPBF is a precision silicon oscillator with a factory-set master frequency of 5.000000MHz. It operates on a single 1.7V to 5.5V supply and requires no external components other than bypass capacitors. The device provides eight selectable output frequencies ranging from 32.768kHz to 5.000MHz via internal dividers controlled by DIVA, DIVB, and DIVC pins. Key electrical characteristics include a maximum frequency error of 0.09% at 25°C, typical RMS period jitter below 0.15%, and a start-up time under 110µs. Typical supply current is 307µA at 3V for the ÷1 setting.

Programmable Timers And Oscillators Feature Summary

• Factory-programmed 5.000000MHz master oscillator with <0.09% frequency error

• Ultra-low power consumption: 307µA typical at 3V, ÷1 setting
• Fast start-up time (<110µs) suitable for battery-operated applications

Programmable Timers And Oscillators Applications

• Microprocessor clock generation
• Power supply clock sources
• Portable and battery-operated devices
• Digitally controlled oscillators

Programmable Timers And Oscillators Procurement Notes

Verify the specific temperature grade 'C' (0°C to 70°C) matches the design requirements, as other grades like 'I' or 'H' are available in the same package. Confirm the '#TRMPBF' suffix indicates Mini-Reel tape and reel packaging containing 500 pieces. Ensure the 8-lead DFN package dimensions align with the PCB footprint layout.

Programmable Timers And Oscillators Selection Notes

Select this part when a fixed 5MHz base frequency is required. Use the DIVA, DIVB, and DIVC pins to scale the output down to frequencies such as 2.5MHz (÷2), 1.25MHz (÷4), or standard baud rates like 39.0625kHz (÷128). Consider the 0.09% accuracy limit and 30ppm/√kHr long-term drift if high stability over time is critical.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930 series of µPower Oscillators. The 'CDCB' designation identifies it as the commercial grade ('C') in an 8-lead 2mm x 3mm Plastic DFN package. The '5.00' suffix specifies the 5.000000MHz master frequency option, distinguishing it from other variants like 4.19, 7.37, 8.00, or 8.19 MHz masters.

Programmable Timers And Oscillators Replacement Considerations

LTC6930IDCB-5.00#TRMPBF offers the same electrical specifications but with an extended industrial temperature range (-40°C to 85°C). LTC6930HDCB-5.00#TRMPBF provides an extended high-temperature range (-40°C to 125°C). Both maintain the identical pinout and package dimensions.
