Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — the compact footprint suits space-constrained designs like SFP modules or PCIe add-in cards, though the no-lead construction requires a reflow profile compatible with the MEMS die inside.","metaTitle":"DSC1121CE1-133.3333 – 133.3333 MHz MEMS XO, CMOS","metaDescription":"DSC1121CE1-133.3333: 133.3333 MHz MEMS oscillator, CMOS output, 2.25-3.6V supply, ±50 ppm stability, -20 to 70°C.
