The MEMS die is sealed at wafer level, which gives the part better shock and vibration immunity than a quartz-based XO – relevant for an automotive ECU that sees 30 g on the engine block. The Enable/Disable function lets a downstream processor gate the clock during low-power sleep modes; the disable current max is 22 mA, versus 32 mA max when enabled. AEC-Q100 qualification means this oscillator passed the automotive stress tests: temperature cycling, ESD, latch-up, and extended high-temperature operating life. The operating temperature range is -20°C to 70°C, which covers cabin and infotainment domains but not the full under-hood band – verify the ambient profile of your ECU location against this range. Frequency stability is ±50 ppm over the full temperature and supply range. For a 156.25 MHz SerDes reference, that translates to a maximum frequency error of ±78 kHz – well within the typical ±100 ppm budget for a 10 GbE PHY. ## Active production – quoted to order Product status is Active. Package is 6-SMD with no lead exposed pad, 7.00 mm x 5.00 mm body, 0.90 mm seated height.","metaTitle":"DSC1123AE1-156.2500T – 156.25 MHz LVDS MEMS Oscillator","metaDescription":"Microchip DSC1123AE1-156.2500T: 156.25 MHz LVDS XO, MEMS resonator, AEC-Q100 qualified, 2.25V–3.63V supply, 6-SMD package.
