LTC6908IDCB-1#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6908IDCB-1#TRMPBF is a precision silicon oscillator from Analog Devices, housed in a 6-lead DFN package. It provides two complementary outputs shifted by 180 degrees. The frequency is set by a single external resistor (RSET) ranging from 10k to 2M ohms, covering an output range of 50kHz to 10MHz. Key electrical parameters include a supply voltage range of 2.7V to 5.5V, typical supply current of 400µA at 5V and 50kHz, and frequency accuracy within ±1.5% maximum at 25°C. It features optional spread spectrum frequency modulation (SSFM) with fixed ±10% spreading for improved EMC performance.

Programmable Timers And Oscillators Feature Summary

• Dual complementary outputs (0°/180° phase shift)
• Frequency programmable via single external resistor (50kHz to 10MHz)
• Spread spectrum frequency modulation (SSFM) with ±10% spreading
• Low power consumption: 400µA typical at 5V

Programmable Timers And Oscillators Applications

• Switching power supply clock reference
• Precision programmable oscillator circuits
• Charge pump driver applications

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRMPBF indicates a mini tape and reel packaging configuration containing 500 pieces. Confirm that the IDCB designation corresponds to the industrial temperature grade (-40°C to 85°C) and the DCB plastic DFN package type. Ensure compatibility with the required PCB footprint for the 6-lead DFN form factor.

Programmable Timers And Oscillators Selection Notes

Select the LTC6908IDCB-1 variant when complementary (180-degree phase-shifted) outputs are required for driving dual switching regulators or charge pumps. Choose this part over the -2 version if quadrature outputs are not needed. Ensure the RSET resistor value falls within the 20k to 400k range for optimal accuracy, though frequencies up to 10MHz are supported with appropriate supply voltages.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6908 family of resistor-set silicon oscillators. The 'IDCB' prefix denotes the industrial temperature range (-40°C to 85°C) and the DFN package. The '-1' suffix specifies the complementary output configuration, distinguishing it from the '-2' variant which provides quadrature outputs. It is designed for low-profile surface-mount applications.
