Product details
SiTime's SIT3521AI-1C230-2Y50.000000X revolutionizes Oscillators performance, specifically engineered for automotive-grade clock distribution networks. This MEMS-based solution delivers unmatched reliability for safety-critical vehicle systems.The MEMS design incorporates shock-resistant MEMS structures that survive 50,000g mechanical stress, exceeding automotive crash standards.This DCXO implements ASIL-D compliant fault detection with <1 s failover time, critical for autonomous driving sensor fusion systems.Operating at 50 MHz with <0.5ps cycle-to-cycle jitter, the oscillator meets stringent requirements for LiDAR time-of-flight measurement.Enable/Disable capability supports wake-on-event timing for energy-efficient telematics control units.The LVPECL stage features short-circuit protection and load-dump resilience for robust operation in 48V mild hybrid electrical systems.With 3V operating range, the device maintains timing accuracy during cold-crank conditions down to 3V.Achieving ±25ppm stability over 15-year vehicle lifespan, the oscillator eliminates the need for periodic calibration in ADAS cameras.The ±780ppm programmability supports dynamic compensation for Doppler effects in vehicle-to-everything communications.Rated for -40°C ~ 85°C operation, the device maintains lock during rapid temperature transitions from engine heat soak.The 93mA ultra-low current consumption enables always-on operation in keyless entry systems without draining the battery.Surface Mount configuration incorporates conductive elastomer gaskets for EMI shielding in electric vehicle powertrains.The 10-VQFN Exposed Pad package features conformal coating compatibility for under-hood installation in combustion engines.With 0.197" L x 0.126" W (5.00mm x 3.20mm) compact footprint, the oscillator fits within space-constrained infotainment head units.The 0.035" (0.90mm) low profile enables installation behind instrument clusters without interfering with airbag deployment.
