Abstract
It briefly introduced The MPC92433 as a dual output LVPECL clock synthesizer is function, internal structure, pin array, programming mode and electronic performance. The MPC92433 is a 3.3V compatible, PLL based clock synthesizer targeted for high performance clock generation in mid-range to high-performance telecom, networking, and computing applications. With output frequencies from 42.50 MHZ to 1428 MHZ and the support of two differential PECL output signals, the device meets the needs of the most demanding.....
