5042

The 5042 series offer high-stability clock oscillator ICs with built-in frequency adjustment functions to achieve ±20ppm frequency change over temperature and load. Use standard 4-pad ceramic packages

Frequency adjustment functions are optimized to minimize the adjustment process, which is performed by writing frequency adjustment data to an onboard EEPROM over a 1-wire serial interface using the enable pin.

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.

The 5042 layout is for wirebond packaging. If you need Flipchip solution, the 5041 offer identical performance and Flipchip layout.
