LTC6908HS6-2#WTRMPBF

LTC®6908 is an easy-to-use precision oscillator. The oscillator frequency is programmed by a single external resistor (RSET) and spread spectrum frequency modulation (SSFM) can be activated for improved electromagnetic compatibility (EMC) performance. The LTC6908 operates with a single 2.7V to 5.5V supply and provides rail-to-rail, 50% duty cycle square wave outputs. A single resistor from 10K to 2M is used to select an oscillator frequency from 50KHz to 10MHz (5V supply). The oscillator can be easily programmed using the simple formula: fOUT =10MHz*10K/RSET. The LTC6908’s SSFM capability modulates the output frequency by a pseudorandom noise (PRN) signal to decrease the peak electromagnetic radiation level and improve EMC performance. The amount of frequency spreading is fixed at ±10% of the centre frequency. Applications include switching power supply clock reference, portable and battery-powered equipment, precision programmable oscillator and charge pump driver.
