Programmable Timers And Oscillators Procurement Notes

Verify the specific package variant, as the HDCB designation indicates an 8-lead DFN package. Confirm that the fixed frequency suffix '-4.19' corresponds to the required 4.194304 MHz output. Check manufacturer documentation for any minimum order quantity requirements associated with factory-set frequencies, as custom frequencies may have different procurement constraints.

Programmable Timers And Oscillators Selection Notes

Select this part when a precise, low-jitter clock source is needed without external tuning components. Ensure the application voltage falls within the 1.7V to 5.5V range. Consider the 105µA to 490µA current consumption profile against battery life requirements. Verify that the 4.194304 MHz frequency meets system timing needs, as other divider options are available in the same series.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930 family of µPower Oscillators. It utilizes a proprietary control architecture to maintain accuracy while minimizing power consumption. The device integrates internal frequency dividers between 1 and 128 based on a fixed master oscillator, eliminating the need for external resistors or capacitors for frequency setting.

Programmable Timers And Oscillators Replacement Considerations

Other variants in the LTC6930 series offer different fixed frequencies such as 32.768kHz, 5.00MHz, 7.3728MHz, 8.00MHz, and 8.192MHz. These share identical pinouts and electrical characteristics except for the output frequency. Package alternatives like the MSOP-8 (LTC6930IMS8) are also available.
