LTC6930CDCB-8.00#TRPBF

Programmable Timers And Oscillators Overview

The LTC6930CDCB-8.00#TRPBF is a precision silicon oscillator from the TimerBlox family, manufactured by Analog Devices Inc. It operates on a single 1.7V to 5.5V supply and requires no external components other than bypass capacitors. The device features a factory-set master frequency of 8.000000MHz with an internal divider selectable via DIVA, DIVB, and DIVC pins, providing output frequencies ranging from 32.768kHz to 8.192MHz. Key electrical characteristics include a maximum frequency error of less than 0.09% at 25°C, a typical start-up time under 110µs, and low power consumption of 491µA typical at 3V with divide-by-1. It is housed in an 8-lead 2mm × 3mm plastic DFN package.

• Ultra-low power operation: 491µA typical at 3V, 8MHz; 198µA typical at 3V, 62.5kHz
• Fast start-up time <110µs with glitch-free output during power-on

Programmable Timers And Oscillators Applications

• Microprocessor clock generation
• Power supply monitoring clocks
• Portable and battery-operated devices requiring frequent power cycles

Programmable Timers And Oscillators Procurement Notes

Verify the ordering suffix #TRPBF indicates Tape and Reel packaging with a standard quantity of 500 pieces. Confirm the 'C' grade designation corresponds to the commercial temperature range of 0°C to 70°C. Ensure the DCB package type matches the required 2mm × 3mm DFN footprint for PCB layout compatibility.

Programmable Timers And Oscillators Selection Notes

Select this part when a fixed 8MHz master frequency is required. Use the DIV pins to achieve specific output frequencies listed in Table 1 of the datasheet. For applications requiring wider temperature ranges, consider the IDCB (–40°C to 85°C) or HDCB (–40°C to 125°C) variants. Ensure load capacitance is managed, as supply current increases significantly with higher capacitive loads.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930 series of µPower Oscillators. The 'CDCB' identifier specifies the Commercial temperature grade (0°C to 70°C) and the 8-lead DCB plastic DFN package. The '8.00' suffix denotes the 8.000000MHz master oscillator frequency. Other options in the series include 4.19, 5.00, 7.37, and 8.19 MHz masters.

Programmable Timers And Oscillators Replacement Considerations

Publicly confirmed substitute part numbers include LTC6930IDCB-8.00#TRPBF for extended industrial temperature range and LTC6930HDCB-8.00#TRPBF for extended high-temperature range. Both maintain identical pinouts and electrical specifications within their respective operating temperature limits.
