Crystal Clock Oscillator
2725N Series
■ Application
● For notebook PC, mobile information terminal, and PC card
■ Features
● CMOS IC is directly driven.
● Product height : 1.0 mm. This is equivalent to height of slim IC
package(TSSOP,TVSOP).
● Current consumption during standby is 15 µA or less. (Max. 40MHz)
● Automatic mounting by taping and IR reflow (lead-free) are possible.
