DSC1123CI2-125.0000

DSC1123CI2-125.0000 is a DSC1123 series low-jitter precision LVDS oscillator. It is a high-performance oscillator that 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. It has a standby feature allowing it to completely power down when the EN pin is pulled low; whereas for DSC1123, only the outputs are disabled when EN is low. It is used in applications such as storage area networks, SATA, SAS, fibre channels, passive optical networks, EPON, 10G-EPON, GPON, 10G-PON, ethernet, 1G, 10GBASE-T/KR/LR/SR, and FCoE, HD/SD/SDI video & surveillance, PCI express: Gen 1 & Gen 2, display port.
