Benefits
■ Services digital televisions and displays, set top boxes,
multifunction printers, and a variety of consumer electronics
applications.
■ Saves PCB space due to small form factor.
■ Enables quick turnaround and flexibility and adaptability to
design changes through programmability.
■ Enables synthesis of highly accurate and stable output clock
frequencies with zero or low ppm error.
■ Enables fine tuning of output clock frequency by adjusting the
crystal load C_Load using programmable internal capacitors.
■ Lowers clock solution cost by pairing a high frequency PLL
programmability with a low cost, low frequency crystal.
■ Enables low power during the power down or output disable
function.
■ Provides flexibility for system applications through selectable
asynchronous or synchronous output enable and disable.
