Silicon oscillator offers up to 8 outputs

Offering spread spectrum frequency modulation, the LTC6909 precision silicon oscillator reduces peak radiated EMI and improves control of switching regulators in multiphase power supplies. The part has eight separate outputs — providing up to eight rail-to-rail 50% duty cycle clock signals — which can be used to enable or disable and phase-synchronize multiple switching regulators.

A single resistor selects the output frequency from 12.5 kHz to 6.67 MHz. Additional features include a supply current of 600 μA typical, a supply voltage from 2.7 to 5.5 V, a start-up time of 260 μs, and a frequency spreading of ±10%. Housed in a 16-lead MSOP package, the part operates from –40° to 125°C. (From $2.46 ea/1,000 — available now.)
