MEMS oscillator with LVDS output for automotive clock trees
The DSC1123DE2-054.0000 is a 54 MHz MEMS-based XO (Standard) producing an LVDS output — a differential signal that rejects common-mode noise over long PCB traces, making it a fit for high-speed clock distribution in automotive ECUs and sensor fusion modules. AEC-Q100 qualification means this oscillator passed the automotive stress tests: temperature cycling, ESD, and latch-up. It is rated for the -20°C to +70°C operating range, suitable for cabin and some chassis-level electronics where the ambient stays within that band. The MEMS resonator replaces a quartz crystal — no mechanical resonance modes to trim, faster start-up, and better immunity to board-level vibration. The 6-SMD no-lead package measures 2.50 mm × 2.00 mm, a compact footprint that fits tight automotive module layouts.
Supply voltage and enable/disable function
Supply voltage range is 2.25 V to 3.63 V, covering 2.5 V and 3.3 V rails commonly found in automotive power domains. The Enable/Disable pin lets a system controller gate the clock — when disabled, supply current drops to 22 mA max from the 32 mA max operating current. Frequency stability is ±25 ppm across the full voltage and temperature range — tight enough for a CAN-FD or 100BASE-T1 reference clock without external trimming.
Active lifecycle — no end-of-life risk
This is a production-grade part suitable for new designs and volume builds.
