The oscillator frequency is set by a single external resistor (RSET). In order to accommodate a wider output frequency range, a programmable divider (divide by 1, 10 or 100) is included. The LTC6902’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.
