LTC6930HDCB-5.00#TRPBF

Programmable Timers And Oscillators Overview

The LTC6930HDCB-5.00#TRPBF is a precision silicon oscillator from Analog Devices, operating within the –40°C to 125°C temperature range. It provides a fixed master frequency of 5.000000MHz with an initial accuracy of less than 0.09% at 25°C. The device utilizes internal dividers (1 to 128) selectable via DIVA, DIVB, and DIVC pins to generate output frequencies ranging from 32.768kHz to 8.192MHz. It operates on a single 1.7V to 5.5V supply, consuming typically 307µA at 3V for the ÷1 setting. Packaged in an 8-lead 2mm × 3mm DFN, it requires no external components other than bypass capacitors.

Programmable Timers And Oscillators Feature Summary

• Frequency error <0.09% max at 25°C
• Start-up time <110µs at all frequencies
• Single 1.7V to 5.5V supply operation
• Typical RMS period jitter <0.15% at V+ = 3V

Programmable Timers And Oscillators Applications

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

Programmable Timers And Oscillators Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging for the HDCB variant. Confirm the 'H' grade designation corresponds to the –40°C to 125°C extended temperature range required for the specific application environment. Ensure the DCB package dimensions match the PCB footprint constraints.

Programmable Timers And Oscillators Selection Notes

Select this part when a factory-set 5MHz master oscillator is needed with high accuracy over industrial temperatures. Choose based on the required output frequency derived from the 5MHz base divided by integers 1–128. Verify that the supply voltage range of 1.7V to 5.5V aligns with the system power rails and that the DFN package size fits the layout.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930 series of µPower oscillators. The 'H' suffix denotes the industrial temperature grade (–40°C to 125°C), while 'DCB' specifies the 8-lead plastic DFN package. The '#TRPBF' suffix indicates lead-free finish and tape and reel shipping format. Other variants include CDCB (commercial) and IDCB (industrial) packages.

Programmable Timers And Oscillators Replacement Considerations

Publicly confirmed substitutes include LTC6930IDCB-5.00#TRPBF for the same temperature range but potentially different manufacturing lot characteristics, or LTC6930CDCB-5.00#TRPBF if only commercial temperature range (0°C to 70°C) is sufficient. MSOP package equivalents like LTC6930HMS8-5.00#TRPBF require footprint changes.
