Precision oscillator needs only one resistor
28 August 2002, Analogue, Mixed Signal, LSI
Linear Technology's LTC6900 is a SOT-23 packaged oscillator IC that generates any frequency from 1 kHz to 20 MHz. The frequency can be accurately set without the need of a crystal, ceramic resonator, capacitor or external reference clock to ±0,6% by adding only a single 0,1% resistor. Accuracy is maintained over all supply and temperature variations, shifting typically less than 0,05%/V and 0,004%/°C. The supply current for a 3 MHz output signal at 3 V is typically just 500 µA. The LTC6900 provides designers of portable or battery-powered equipment with an easy, small and robust clock signal, ideal for localised clocks. A localised clock on a PCB eliminates problems of routing centrally-generated clock signals all over the board. |
