Silicon Oscillator with Fixed Frequencies
Mon, 02/02/2004 - 8:04am
Maxim introduces the MAX7375 silicon oscillator. Available in 3-pin SC70 and SOT23 packages, this device is an integrated oscillator with fixed frequencies that requires no additional components for setting or adjusting the frequency. With a fast 5 microseconds startup time, the oscillator frequency is generated directly without use of a phase-locked loop (PLL). The MAX7375 replaces ceramic resonators, crystals, and crystal oscillator modules as the clock source for microcontrollers and UARTs. This device resists vibration and EMI under both manufacturing and operating conditions. High-output drive current (± 10 mA) and the absence of high-impedance nodes make the MAX7375 resistant to dirty or humid operating conditions. The MAX7375 is guaranteed for operation over the 55°C to +135°C temperature range and is specified over the automotive temperature range (㫀°C to +125°C). Initial accuracy is 2% (max) and temperature performance is 50 ppm/°C (typical) and 325 ppm/°C (maximum). At a supply voltage of 2.7 V, the supply current is 1 mA for the 8 MHz frequency device.
