The factory programmable Si51210 is industry’s lowest power, smallest  
footprint and frequency flexible programmable clock generator targeting  
low power, low cost and high volume consumer and embedded  
applications. The device operates from a single crystal or an external  
clock source and generates 1 to 2 outputs up to 200 MHz. They are  
factory programmed to provide customized output frequencies, control  
inputs and ac parameter tuning like output drive strength that are  
optimized for customer board condition and application requirements.
