100 MHz LVDS timing for automotive and industrial
The DSC1123AI5-100.0000 is a 100 MHz LVDS-output MEMS oscillator from Microchip's DSC1123 series, built on a silicon MEMS resonator rather than a quartz crystal. AEC-Q100 qualification (Grade 2 implied by the temperature range) means this part has passed automotive-grade reliability stress tests — temperature cycling, ESD, latch-up — and is suitable for under-hood or cabin electronics where a standard quartz oscillator would risk failure from vibration or thermal shock.
Supply voltage and power budget
The wide supply range of 2.25V to 3.63V lets it run directly off a 2.5V or 3.3V rail without an extra LDO, simplifying the power tree. Max supply current is 32 mA when enabled, dropping to 22 mA when the Enable/Disable pin is pulled low — useful for power-cycling the clock in sleep modes.
Package and board layout
Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm, this is a standard 7x5 mm oscillator footprint. The exposed pad on the underside should be soldered to a ground plane for thermal dissipation and mechanical stability, especially in automotive environments with wide temperature swings.
Active lifecycle — no end-of-life risk
This part is suitable for both new designs and ongoing production without an imminent obsolescence risk.
