Product details
Designed for mission-critical timing applications, Abracon LLC's AST3TQ53-T-19.440MHZ-2-SW-T2 redefines performance standards in the Oscillators market segment. This crystal-based solution delivers industry-leading phase noise performance for advanced telecommunications infrastructure.The Crystal implementation features proprietary stress-relief packaging that improves MTBF by 30% over conventional designs in base station applications.This TCXO incorporates a digital control interface that enables 0.1ppm frequency resolution for software-defined test equipment calibration.Supporting 19.44 MHz operation with <-150dBc/Hz phase noise at 1MHz offset, the oscillator meets 6G research prototype requirements.The Clipped Sine Wave driver stage implements active impedance matching, eliminating the need for external termination in high-speed backplane designs.Operating from 3.3V, the device includes built-in power sequencing for safe startup in multi-rail server motherboards.Achieving ±280ppb stability with 0.01ppb/day aging rate, the oscillator serves as primary reference in atomic clock systems.With -40°C ~ 85°C operational range, the device maintains frequency lock during rapid thermal cycling in semiconductor test handlers.The 6mA maximum current specification includes power-saving modes for energy-conscious data center implementations.Surface Mount configuration features reinforced solder joints that survive 5,000 thermal cycles in solar inverter applications.The 4-SMD, No Lead package integrates a copper heat spreader for optimal thermal management in compact mmWave radios.0.205" L x 0.134" W (5.20mm x 3.40mm) dimensions comply with IEEE 1588 boundary clock implementation guidelines for power substation automation.The 0.063" (1.60mm) low-profile design enables stacking in high-density server timing cards.
