LTC6930CDCB-5.00#TRPBF

Programmable Timers And Oscillators Overview

The LTC6930CDCB-5.00#TRPBF is a precision silicon oscillator from Analog Devices, operating within the 32.768kHz to 8.192MHz range. It features a factory-set master frequency of 5.000000MHz with internal dividers selectable via DIVA, DIVB, and DIVC pins. The device operates on a single 1.7V to 5.5V supply, consuming typically 307µA at 3V for the base frequency. It offers a maximum frequency error of less than 0.09% at 25°C and a start-up time under 110µs. Packaged in an 8-lead 2mm × 3mm DFN, it requires no external components other than bypass capacitors.

• Fast start-up time (<110µs) suitable for battery-powered applications

Programmable Timers And Oscillators Applications

• Microprocessor clock generation
• Power supply clock monitoring
• Portable and battery-operated devices

Programmable Timers And Oscillators Procurement Notes

Verify the specific temperature grade 'C' (0°C to 70°C) against application requirements, as other grades like 'I' or 'H' are available. Confirm the package type is the 8-lead DFN and the suffix '#TRPBF' indicates tape and reel packaging. Ensure the master frequency matches the system design needs, as custom frequencies require minimum order quantities.

Programmable Timers And Oscillators Selection Notes

Select this part when a fixed 5MHz master source is required with digital divide control. Consider the 0°C to 70°C operating range; if wider temperatures are needed, choose the IDCB or HDCB variants. Evaluate supply current impact based on load capacitance, as driving larger capacitive loads increases power dissipation significantly above the specified 5pF test condition.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930 family of µPower oscillators. The 'CDCB' designation identifies the commercial temperature grade (0°C to 70°C) and the DCB plastic DFN package. The '5.00' specifies the 5.000000MHz master oscillator frequency. The '#TRPBF' suffix denotes lead-free finish and tape and reel shipping format.
