LTC6902CMS#PBF

LTC6902 is a precision, low power and easy-to-use oscillator. It provides multiphase outputs in a small package. The oscillator frequency is set by a single external resistor (RSET). This device also provides an optional spread spectrum frequency modulation (SSFM) capability that can be activated and controlled by an additional external resistor (RMOD). This device's SSFM capability modulates the oscillator’s frequency by a pseudorandom noise (PRN) signal to spread the oscillator’s energy over a wide frequency band. This spreading decreases the peak electromagnetic radiation level and improves electromagnetic compatibility (EMC) performance. The amount of frequency spreading is programmable by a single additional external resistor (RMOD) and is disabled by grounding the MOD pin.
