LTC6930CDCB-8.19

Programmable Timers And Oscillators Overview

The LTC6930CDCB-8.19 is a precision silicon oscillator from Analog Devices Inc., designed for low-power applications. It operates on a single supply voltage ranging from 1.7V to 5.5V, enabling functionality with a single Li-Ion cell or two AA alkaline cells. The device features a frequency error of less than 0.09% maximum at 25°C and an exceptionally fast startup time of under 110µs at all frequencies. Typical supply current is 105µA at 32kHz with a 3V supply and 490µA at 8MHz with a 3V supply. It requires no external components other than power supply bypass capacitors.

Programmable Timers And Oscillators Procurement Notes

Verify the specific package type (DCB) and operating temperature range (C for Commercial) against the target design requirements. Confirm that the fixed output frequency of 8.192MHz aligns with system timing needs, as custom frequencies require minimum order sizes. Check RoHS compliance status and ensure proper handling for surface-mount assembly.

Programmable Timers And Oscillators Selection Notes

Select this component when a fixed 8.192MHz clock source is required with minimal external circuitry. Ensure the application supports the 1.7V to 5.5V input range. Consider the typical RMS period jitter specification of less than 0.15% at 3V if signal integrity is critical. Verify that the commercial temperature range meets environmental constraints.

Programmable Timers And Oscillators Part Context

This part belongs to the LTC6930 series of precision µPower oscillators. The suffix CDCB indicates the specific frequency option (8.192MHz), the commercial temperature grade, and the 8-lead DFN package. It is distinct from other variants like the IMS8 package or different frequency options within the same family.

Programmable Timers And Oscillators Replacement Considerations

Direct substitutes include other LTC6930 variants with different frequencies or packages, such as LTC6930CMS8-8.00, provided the frequency difference is acceptable. Cross-family replacements are not directly supported by verified public data.
