LTC6930HDCB-7.37#TRPBF

Programmable Timers And Oscillators Overview

The LTC6930HDCB-7.37#TRPBF is a precision silicon oscillator from Analog Devices, operating within the –40°C to 125°C temperature range. It provides a nominal master frequency of 7.3728MHz with a maximum initial frequency error of 0.09% at 25°C. The device supports eight selectable output frequencies ranging from 32.768kHz to 8.192MHz via internal dividers controlled by DIVA, DIVB, and DIVC pins. Powered by a single 1.7V to 5.5V supply, it consumes typical currents between 183µA at 32kHz and 660µA at 8MHz (V+ = 3V). Packaged in an 8-lead 2mm × 3mm DFN, it features fast start-up times under 110µs and low jitter specifications.

Programmable Timers And Oscillators Procurement Notes

Verify the ordering suffix #TRPBF indicates Tape and Reel packaging for this specific part number. Confirm the 'H' grade designation corresponds to the –40°C to 125°C extended temperature range required for the application environment. Ensure the DCB package dimensions align with the PCB footprint layout guidelines provided in the datasheet.

Programmable Timers And Oscillators Selection Notes

Select the LTC6930HDCB-7.37 variant when an industrial temperature range up to 125°C is necessary. The base frequency of 7.3728MHz allows division down to standard baud rates like 57.6kHz or up to 7.3728MHz. Compare against the IDCB grade if only –40°C to 85°C coverage is sufficient, as it may offer different availability or cost structures while maintaining similar electrical performance.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930 series of µPower oscillators manufactured by Analog Devices. The 'H' suffix denotes the high-temperature industrial grade, while 'DCB' specifies the 8-lead plastic DFN package. The '#TRPBF' suffix confirms lead-free finish and tape-and-reel shipping format. This family utilizes a proprietary control architecture to maintain accuracy without external tuning components.

Programmable Timers And Oscillators Replacement Considerations

LTC6930IDCB-7.37#TRPBF offers identical electrical characteristics but is rated for –40°C to 85°C instead of –40°C to 125°C.
