Description

The DSC1105 & DSC1125 series of low jitter automotive oscillators utilizes a proven silicon MEMS technology to provide excellent jitter and stability over a wide range of supply voltages and temperatures. By eliminating the need for quartz or SAW technology, MEMS oscillators significantly enhance reliability and accelerate product development, while meeting stringent clock performance criteria for a variety of communications, storage, and networking applications. DSC1105 and DSA1125 are programmed with lowest output drive strength for reduced EMI. DSC1105 has a standby feature allowing it to completely power-down when EN pin is pulled low; whereas for DSC1125, only the outputs are disabled when EN is low. Both oscillators are available in industry standard packages, including the smallest 2.5mm x 2.0mm, and are "drop-in" replacements for standard 4-pin CMOS quartz crystal oscillators.
