The LTC6909IMS#PBF is a Precision Oscillator offers spread spectrum frequency modulation (SSFM), which can be enabled to improve electromagnetic compatibility (EMC) performance. Eight separate outputs provide up to eight rail-to-rail, 50% duty cycle clock signals. Using three logic inputs, the outputs are configured for phase separation, ranging from 45 to 120° (three to eight phases). The clock outputs can also be held low or configured for Hi-Z. It can be used in applications requiring only one or two output phases. It can provide 1-, 2-, 3-, 4-, 5-, 6-, 7- or 8-phase synchronized outputs.
