LTC6905IS5-100

Silicon Oscillator 100MHz/ 50MHz/ 25MHz CMOS Automotive 5Pin TSOT-23

DESCRIPTION

The LTC® 6905-XXX series of parts are precision, fixed frequency, silicon oscillators designed to minimize board space while maximizing accuracy and ease of use. Programmed at the factory to a fixed frequency, the LTC6905-XXX series of parts need no external trim components. An internal three-state divider allows for division of the master clock by 1, 2 or 4, providing 3 frequencies

for each device.

The LTC6905-XXX series operate with a single 2.7V to 5.5V power supply and provide a rail-to-rail, 50% duty cycle, square wave output. The OE pin will disable the output when brought low and synchronously enable the output when brought high, avoiding pulse slivers.
