Features  
The PT7C4781 is low cost, multi-clock generator Phase  
Lock Loop (PLL).  
3.3V operation  
The PT7C4781 can generate three clocks from a 12MHz  
Low Jitter (Typ. 200ps). High accuracy outputs  
12MHz master clock inout  
reference input frequency.  
The device gives customers both cost and space  
3 kinds clock output: 27MHz, 24.576MHz and  
12.288MHz  
savings by eliminating external components and enables  
customers to achieve the very low jitter performance  
needed for high performance audio digital-to-analog  
converters (DAC) and/or analog-to-digital converters  
(ADC). The PT7C4781 is ideal for MPEG-2  
applications which use a 27MHz master clock such as  
DVD players, DVD add-on cards for multimedia PCs,  
digital HDTV systems, and set-top boxes.
