MICROCHIP DSC557-0344FL1T Clock Generator IC, 100MHz, 2 Outputs, 3.6V, QFN-EP-14, -40°C to 105°C

DSC557-0344FL1T is a ±50ppm, two output PCIe clock generator for automotive. It uses a proven silicon MEMS technology to provide 100MHz differential output clocks with 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. Application includes Ethernet, 1G, 10GBASE-T/KR/LR/SR, and FcoE, routers and switches, gateways, VoIP, Wireless APs, passive optical networks (communications/networking), SAN, NAS, SSD, JBOD (storage), industrial, medical, and avionics, security systems and office automation, digital signage, POS, and others (embedded applications), smart TV, Blu-Ray, STB (consumer electronics).
