LTC6930CDCB-4.19#TRPBF

Programmable Timers And Oscillators Overview

The LTC6930CDCB-4.19#TRPBF is a precision silicon oscillator from Analog Devices, operating within a frequency range of 32.768kHz to 8.192MHz. It features a maximum frequency error of less than 0.09% at 25°C and supports a single supply voltage between 1.7V and 5.5V. The device draws typical supply currents ranging from 105µA at 32kHz to 490µA at 8MHz when powered by 3V. It utilizes an internal master oscillator with digital dividers controlled via DIVA, DIVB, and DIVC pins to select one of eight frequencies. The component is housed in an 8-lead (2mm × 3mm) plastic DFN package and operates over a commercial temperature range of 0°C to 70°C.

Programmable Timers And Oscillators Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging for this part number. Confirm that the 'C' grade designation corresponds to the 0°C to 70°C operating temperature range required for the application environment. Ensure compatibility with the 8-lead DFN footprint during PCB layout.

Programmable Timers And Oscillators Selection Notes

Select this model for applications requiring a factory-set 4.194304MHz base frequency with digital division capabilities up to ÷128. Choose the DCB package for compact board space requirements. Consider the H or MP grades if operation outside the 0°C to 70°C commercial range is necessary.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930 series of µPower oscillators. It shares the same core architecture and pinout as other variants like the LTC6930IDCB and LTC6930HDCB, differing primarily in temperature rating and base frequency options. The DCB package is a tiny 2mm × 3mm DFN suitable for space-constrained designs.

Programmable Timers And Oscillators FAQ

How is the output frequency determined?

The output frequency is derived from a fixed master oscillator (4.194304MHz for this part) divided by an integer N (1 to 128), selected by the logic states of the DIVA, DIVB, and DIVC pins.

What is the start-up time specification?

The start-up time is typically less than 110µs from power application to the first accurate output cycle, with the output held low for the first 50µs to prevent glitches.

Does the device require external components for frequency setting?

No, the LTC6930 requires no external components other than power supply bypass capacitors to set the frequency; it is configured entirely via digital input pins.
