The 5043 series offer high-stability clock oscillator ICs with built-in frequency adjustment functions to achieve better than ±15ppm frequency change over temperature and load. No extra external contacts; this design fit 4-pad ceramic package for plug-in compatibility.
Frequency adjustment functions are optimized by implementing a minimal adjustment process to improve frequency stability. The function writes frequency adjustment data to a built-in EEPROM over a 1-wire serial interface. Jitter and phase noise performance meet application requirement for WiMAX (Worldwide Interoperability for Microwave Access) and PLC (Power Line Communication) that require high frequency stability.
