The LVDS output swings 350 mV typical into a 100-Ω differential termination, which mates directly with standard LVDS receivers on FPGAs, ASICs, or PHYs without external level translation. The MEMS resonator eliminates the quartz aging and shock sensitivity that can pull a crystal oscillator off frequency in a high-vibration environment like an engine bay or a factory-floor drive. ## AEC-Q100 qualification and supply voltage flexibility Rated AEC-Q100, this oscillator is qualified for automotive stress conditions including temperature cycling, ESD, and latch-up — suitable for under-hood or cabin-domain ECUs that must survive 85°C ambient and cold-crank transients. The supply voltage spans 2.25 V to 3.63 V, covering 2.5 V and 3.3 V rails commonly found in automotive and industrial systems. Maximum supply current is 32 mA when enabled and 22 mA when disabled via the Enable/Disable pin — the disable function lets a system power down the clock tree in sleep mode without a separate load switch. ## Active lifecycle — design-in ready Sourced through independent distribution; quoted to order against the BOM quantity. Housed in a 6-SMD no-lead package measuring 3.20 mm × 2.50 mm with a seated height of 0.90 mm. The 0.50 mm pitch pads require a standard 6-pin land pattern — no via-in-pad needed. The MEMS die is encapsulated, so no special handling beyond standard MSL precautions.","metaTitle":"DSC1123CI2-148.5000T – 148.5 MHz LVDS MEMS XO, AEC-Q100","metaDescription":"Microchip DSC1123CI2-148.5000T: 148.5 MHz LVDS MEMS oscillator, ±25 ppm stability, -40°C to 85°C, AEC-Q100 qualified.
