www.DataSheet4U.com SM8720AV 3-PLL Multi-Output Clock Generator OVERVIEW The SM8720AV is a clock generator IC with 3 built-in PLLs. It can simultaneously output a 27MHz master clock and three other clocks with different frequency (CLK1OUT, CLK2OUT, CLK3OUT) derived from the master clock. The 3 generated clocks can be independently turned ON/OFF using control pins and the frequency of CLK3OUT can be switched, allowing unneeded clocks within a system to be switched OFF thereby reducing current consumption.
