3-PLL Multi-Output Clock Generator

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 fre- quency of CLK3OUT CAN be switched, allowing unneeded Clocks within a system to be switched OFF thereby reducing current consumption. The master Clock supplied by high-stability crystal Oscillator external input, allows Clocks to be generated with high precision and low jitter and which require no frequency adjustment, making the SM8720AV ideal for digital still cameras and other applications which require multiple high-preci- sion Clocks By Nippon Precision Circuits Inc, (NPC)
