LTC6909IMS#TRPBF

LTC6909 is a easy to use precision oscillator that can provide 1-, 2-, 3-, 4-, 5-, 6-, 7- or 8-phase synchronized outputs. It also offers spread spectrum frequency modulation (SSFM), which can be enabled to improve electromagnetic compatibility (EMC) performance. Eight separate outputs provide up to eight rail-to-rail, 50% duty cycle clock signals. Using three logic inputs, the outputs are configured for phase separation, ranging from 45° to 120° (three to eight phases). It can be used in applications requiring only one or two output phases. It is used in applications such as synchronizing multiple switching power supplies.

• Optional spread spectrum frequency for improved EMI performance
• ±10% frequency spreading, outputs can be held low or floated (Hi-Z)
• Operating voltage range from 2.7V to 5.5V
• Fast start-up time, first cycle accurate
• Outputs are high impedance until frequency settles
• Output rise time is 1.6ns typical at (V+ = 5V, TA = 25°C)
• Output fall time is 1.6ns typical at (V+ = 5V, TA = 25°C)
• Duty cycle is 50% typical at (TA = 25°C)
• Operating temperature is -40°C to 85°C
• Package style is 16-lead plastic MSOP
