At 148.35 MHz, that matters because the rise time is short enough that a single-ended clock would radiate into adjacent traces. The supply voltage range of 2.25V to 3.63V lets it run from a 2.5V or 3.3V rail without an extra regulator, and the Enable/Disable function lets you gate the clock for power-saving modes — the disable current drops to 22 mA max from 32 mA max. ## Active lifecycle — no last-time-buy panic The 6-SMD No Lead Exposed Pad package (7.00mm x 5.00mm) is a common footprint shared with other DSC1123 frequency variants, so a BOM swap to a different frequency in the same series is a direct drop-in.","metaTitle":"DSC1123AI5-148.3500 MEMS XO – LVDS, 148.35 MHz, AEC-Q100","metaDescription":"Microchip DSC1123AI5-148.3500: MEMS-based XO, LVDS output at 148.35 MHz, ±10 ppm stability, AEC-Q100 qualified, active lifecycle.
