Product details
Designed for mission-critical timing applications, SiTime's SIT5156AECFA-33E0-19.440000 redefines performance standards in the Oscillators market segment. This crystal-based solution delivers industry-leading phase noise performance for advanced telecommunications infrastructure.The MEMS 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.Enable/Disable capability supports clock gating architecture in AI accelerator chips, reducing dynamic power consumption by 15%.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 ±1ppm stability with 0.01ppb/day aging rate, the oscillator serves as primary reference in atomic clock systems.With -40°C ~ 105°C operational range, the device maintains frequency lock during rapid thermal cycling in semiconductor test handlers.Surface Mount configuration features reinforced solder joints that survive 5,000 thermal cycles in solar inverter applications.The 10-SMD, No Lead package integrates a copper heat spreader for optimal thermal management in compact mmWave radios.0.197" L x 0.126" W (5.00mm x 3.20mm) dimensions comply with IEEE 1588 boundary clock implementation guidelines for power substation automation.The 0.042" (1.06mm) low-profile design enables stacking in high-density server timing cards.
