Analog Devices Inc. LTC6908IS6-2#TRPBF: Precision Resistor Set Oscillator with Spread Spectrum Modulation

The LTC6908IS6-2#TRPBF is a high-performance, silicon oscillator from Analog Devices Inc., designed to offer a versatile clock generation solution with spread spectrum frequency modulation capability. This precision oscillator is a part of the LTC6908 series and is packaged in a compact, surface-mount, 6-lead TSOT-23 package, making it ideal for space-constrained applications where electromagnetic interference (EMI) must be minimized.

The LTC6908IS6-2#TRPBF operates over a single supply voltage range of 2.7V to 5.5V, providing a wide range of frequency options that can be easily programmed using external resistors. This feature simplifies design and reduces component count, as no external capacitors or inductors are required. The device can generate frequencies from 50kHz to 10MHz, which are divided down to produce two outputs. These outputs are 180 degrees out of phase with each other, further enhancing the EMI reduction capabilities of the device.

One of the key features of the LTC6908IS6-2#TRPBF is its spread spectrum frequency modulation, which helps to significantly reduce peak EMI emissions. By modulating the frequency of the output clock, the energy is spread over a wider bandwidth, thus lowering the peak amplitude of the spectral components. This makes the LTC6908IS6-2#TRPBF an excellent choice for sensitive applications where EMI compliance is critical, such as in automotive, industrial, and telecommunications equipment.

The device also boasts a high level of integration and functionality, with an onboard power-down feature that reduces the supply current to less than 20µA, providing power savings in applications where the clock signal is not needed continuously. Additionally, the LTC6908IS6-2#TRPBF is characterized for operation from -40°C to 125°C, ensuring reliable performance across a broad range of temperature conditions.

In summary, the LTC6908IS6-2#TRPBF from Analog Devices Inc. is a versatile, easy-to-use oscillator that provides precise frequency generation with the added benefit of spread spectrum modulation for EMI reduction. Its compact footprint, low power consumption, and temperature resilience make it an excellent choice for a diverse array of electronic applications.
