Product details
Abracon LLC's AST3TQ-T-19.440MHZ-50-SW revolutionizes Oscillators performance, specifically engineered for automotive-grade clock distribution networks. This MEMS-based solution delivers unmatched reliability for safety-critical vehicle systems.The Crystal design incorporates shock-resistant MEMS structures that survive 50,000g mechanical stress, exceeding automotive crash standards.This TCXO implements ASIL-D compliant fault detection with <1 s failover time, critical for autonomous driving sensor fusion systems.Operating at 19.44 MHz with <0.5ps cycle-to-cycle jitter, the oscillator meets stringent requirements for LiDAR time-of-flight measurement.The Clipped Sine Wave stage features short-circuit protection and load-dump resilience for robust operation in 48V mild hybrid electrical systems.With 3.3V operating range, the device maintains timing accuracy during cold-crank conditions down to 3V.Achieving ±50ppb stability over 15-year vehicle lifespan, the oscillator eliminates the need for periodic calibration in ADAS cameras.Rated for -40°C ~ 85°C operation, the device maintains lock during rapid temperature transitions from engine heat soak.The 7mA 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 4-SMD, No Lead package features conformal coating compatibility for under-hood installation in combustion engines.With 0.276" L x 0.197" W (7.00mm x 5.00mm) compact footprint, the oscillator fits within space-constrained infotainment head units.The 0.079" (2.00mm) low profile enables installation behind instrument clusters without interfering with airbag deployment.
