This frequency is a common reference for 10 Gigabit Ethernet, Fibre Channel, and high-speed serial transceivers where LVPECL's differential swing provides noise immunity over long board traces. ## Supply voltage flexibility and temperature grade Operating from a 2.25V to 3.63V supply, this oscillator runs directly off a 3.3V or 2.5V rail without an intermediate regulator. Housed in a 6-VDFN package measuring 3.20mm x 2.50mm with a seated height of 0.90mm, the device occupies minimal PCB area.","metaTitle":"DSC1222CI2-156M2935T MEMS XO 156.2935 MHz LVPECL - Microchip","metaDescription":"Active MEMS oscillator, 156.2935 MHz LVPECL output, ±25 ppm stability, -40°C to 85°C, 6-VDFN.
