MEMS oscillator at 409.375 MHz with LVDS output
Supply voltage spans 2.25V to 3.63V, so it runs on a 2.5V or 3.3V rail without a separate LDO — the Enable/Disable pin lets the system shut the oscillator off, dropping supply current from 32 mA max to 22 mA max.
Automotive-grade timing for harsh environments
Rated AEC-Q100 — this is the automotive IC qualification covering temperature cycling, ESD, and PPAP documentation. Package is 6-SMD no-lead, 3.20 mm x 2.50 mm — a standard 3.2x2.5 mm footprint that matches many quartz oscillator pads, but the MEMS die has different decoupling needs: place a 100 nF ceramic within 2 mm of the supply pin to keep the internal PLL clean.
Active production — no redesign pressure
The DSC1123 series is an ongoing Microchip line; the DSC1123CI5-409.3750T can be designed in today and sourced for the full production run.
