The following is the circuit diagram of the **LTC6909 package structure and application circuit**.
The **LTC6909** is a user-friendly, high-precision oscillator that delivers 1 to 8 synchronized phase outputs. It also features **Spread Spectrum Frequency Modulation (SSFM)**, which helps improve electromagnetic compatibility (EMC) performance in your design.
This device is ideal for applications requiring multiple clock signals with precise timing control. The LTC6909 offers up to eight independent, rail-to-rail, 50% duty cycle clock outputs. These outputs can be configured using three logic inputs to set the phase separation between 45° and 120°, corresponding to 3 to 8 phases. Additionally, the clock output can be set to low or high impedance mode based on your requirements.
A single resistor, combined with the phase configuration, determines the output frequency according to the formula:
**fOUT = 20MHz × 10k / (RSET × PH)**
Where **PH** can be set to 3, 4, 5, 6, 7, or 8 depending on the desired number of output phases.
The LTC6909 is available in an **MS-16** package, making it suitable for a wide range of industrial and communication applications.
Here’s a look at the **LTC6909 package** and its **typical application circuit**:
Whether you're designing a complex system requiring multiple synchronized clocks or looking to enhance your board's EMC performance, the LTC6909 provides a flexible and reliable solution.
