Description
The VT8225 is a universal clock generator for motherboard design. The product at a glimpse:
1. Generates all kinds of required clocks for CPU and bus operation from 6 Mhz to 80 Mhz.
2. Eliminates at least two oscillators, which are oscillators for CPU and 14.318MHz oscillator.
3. Simplifies inventory: VT8225 covers required main clock for the motherboard design.
4. Provides a reliable clock for the PLL design.
5. Is pin-to-pin compatible to oscillator.
