Linear Technology Silicon Oscillator "LTC6909"
LTC6909 - Linear Technology
Eight clock outputs that can be set to eight phases.
**Overview** The LTC6909 features eight individual outputs, providing up to eight rail-to-rail 50% duty cycle clock signals. These outputs can be used to enable/disable multiple switching regulators or to achieve phase synchronization. Phase synchronization offers numerous design advantages, including improved EMI performance, reduced input and output ripple current, and enhanced load transient response. Additionally, by using three logic inputs, the phase relationship between these outputs can be set within a range of 45° to 120°, or the outputs can be set to logic "L" or high-impedance state. A single resistor is used to select the output frequency in the range of 12.5 kHz to 6.67 MHz. The LTC6909 also includes a Spectrum Spread Frequency Modulation (SSFM) feature, which is a technique for modulating the clock frequency with a pseudo-random signal. SSFM can be easily enabled and provides a method to reduce peak electromagnetic radiation. The amount of frequency spreading is fixed at ±10% of the center frequency, and the user can select one of three modulation rates.
