LTC6908CS6-1#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6908CS6-1#TRMPBF is a precision silicon oscillator in a 6-lead TSOT-23 package, manufactured by Analog Devices Inc. It provides two complementary outputs shifted by 180 degrees. The oscillation frequency is set by a single external resistor (RSET) connected between the SET and V+ pins, covering a range from 50kHz to 10MHz at a 5V supply. The device operates on a single 2.7V to 5.5V supply with a typical supply current of 400µA at 50kHz. It features optional spread spectrum frequency modulation (SSFM) to improve electromagnetic compatibility, with a fixed ±10% frequency spreading capability.

Programmable Timers And Oscillators Feature Summary

• Dual complementary outputs (LTC6908-1) with 180-degree phase shift
• Frequency programming via single external resistor (RSET)
• Spread spectrum frequency modulation (SSFM) for EMC improvement
• Operates on single 2.7V to 5.5V supply

Programmable Timers And Oscillators Applications

• Switching power supply clock reference
• Portable and battery-powered equipment
• Precision programmable oscillator
• Charge pump driver

Programmable Timers And Oscillators Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a tape and reel configuration with a minimum quantity of 500 pieces. Confirm the temperature grade 'C' corresponds to the specified commercial operating range. Ensure the component matches the exact pinout and package dimensions required for the target PCB layout.

Programmable Timers And Oscillators Selection Notes

Select this variant for applications requiring complementary outputs rather than quadrature. The CS6 designation specifies the commercial temperature range (0°C to 70°C). For wider temperature ranges, consider the IS6 or HS6 variants. Ensure the RSET value falls within the recommended 20k to 400k range for optimal accuracy.

Programmable Timers And Oscillators Part Context

This part belongs to the LTC6908 family of resistor-set silicon oscillators. The -1 suffix denotes the version with complementary (0°/180°) outputs, distinct from the -2 version which provides quadrature (0°/90°) outputs. The S6 package refers to the 6-lead plastic TSOT-23 form factor.
