The 32 mA max supply current is the total draw including the output buffer. 6-SMD package with exposed pad, 7.00 mm x 5.00 mm body, 0.90 mm seated height — the exposed pad needs a thermal via pattern under the part for heat sinking; the pad is tied to ground on the PCB.","metaTitle":"DSC1123AI2-312.5000 MEMS XO, LVDS, 312.5 MHz, AEC-Q100","metaDescription":"Microchip DSC1123AI2-312.5000 MEMS XO, LVDS output at 312.5 MHz, ±25 ppm stability, AEC-Q100 qualified.
