Description
The factory programmable Si51219 is a low power, small 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 3 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. A separate VDDO supply pin supports
clock output at a different voltage level.
