LTC6930HDCB-8.00#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6930HDCB-8.00#TRMPBF is a precision silicon oscillator from the Analog Devices TimerBlox family, housed in an 8-lead 2mm × 3mm plastic DFN package. It provides a nominal master frequency of 8.000000MHz with a maximum initial frequency error of 0.09% at 25°C. The device operates on a single supply voltage ranging from 1.7V to 5.5V and supports output frequencies from 32.768kHz to 8.192MHz via internal dividers controlled by DIVA, DIVB, and DIVC pins. Typical supply current is 491µA at 3V with no division, and start-up time is under 110µs.

Programmable Timers And Oscillators Applications

• Digitally Controlled Oscillator
• Microprocessor Clock
• Power Supply Clock
• Portable and Battery Operated Devices

Programmable Timers And Oscillators Procurement Notes

Verify the part marking LCKX on the component body to confirm the specific 8.00MHz variant within the HDCB package. Ensure the exposed pad (Pin 9) is soldered to a ground plane for proper thermal dissipation and electrical connection. Confirm the temperature grade H corresponds to the required –40°C to 125°C operating range for the application environment.

Programmable Timers And Oscillators Selection Notes

Select this part when a fixed 8MHz master clock is needed with high accuracy and low power consumption. The output frequency can be divided by integers from 1 to 128 using the digital DIV inputs. For applications requiring lower power at reduced frequencies, utilize the divide settings to scale down the 8MHz master oscillator while maintaining jitter specifications.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930 series of µPower oscillators. The 'H' suffix denotes the extended industrial temperature range of –40°C to 125°C. The 'DCB' indicates the 8-lead 2mm × 3mm DFN package. The '#TRMPBF' suffix specifies the lead-free finish, tape and reel mini packaging containing 500 pieces.
