The 18.432 MHz frequency is a common multiple for 10/100/1000BASE-T Ethernet, PCIe reference clocks, and serial transceiver PLLs. ## Supply voltage range and power budget The supply voltage spans 2.25V to 3.6V, covering 2.5V and 3.3V rails without an external regulator. ## Package and board layout notes The 6-SMD no-lead package measures 5.00 mm x 3.20 mm with a seated height of 0.90 mm. The 0.197\" x 0.126\" footprint matches industry-standard 5x3.2 mm oscillator pads.","metaTitle":"DSC1122BE2-018.4320T MEMS XO – 18.432 MHz LVPECL ±25 ppm","metaDescription":"Active Microchip DSC1122 series MEMS oscillator, 18.432 MHz, LVPECL output, ±25 ppm stability, 2.25V–3.6V supply, -20°C to 70°C.
