The 6-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a standard MEMS oscillator footprint that fits most high-speed clock sockets without layout changes. ## Supply voltage range and power budget Maximum supply current is 42 mA; with the output disabled, it drops to 22 mA.","metaTitle":"DSC1124CI5-156.2578T MEMS XO 156.2578 MHz HCSL ±10 ppm -","metaDescription":"DSC1124CI5-156.2578T XO (Standard) from Microchip Technology. 156.2578 MHz HCSL output, ±10 ppm stability, -40°C to 85°C, enable/disable.
