Key Features

The LTC6902CMS#TRPBF is a precision, low-power oscillator that provides multiphase outputs in a compact package. Its frequency is set by a single external resistor, simplifying design and reducing component count. The device supports 2-, 3-, or 4-phase outputs, offering flexibility for various applications. Additionally, it features optional spread spectrum frequency modulation (SSFM), which can be activated and controlled by an additional external resistor. This SSFM capability modulates the oscillator’s frequency with a pseudorandom noise signal, effectively spreading the oscillator’s energy over a wide frequency band. Consequently, this reduces peak electromagnetic radiation levels and improves electromagnetic compatibility (EMC) performance. The oscillator operates over a wide frequency range from 5 kHz to 20 MHz and maintains high accuracy and stability across its operating range.

Applications

Switching power supply clock reference
Portable and battery-powered equipment
PDAs
Cell phones
Clocking switched capacitor filters
