The PI6C49X0210-A is a high performance multi-voltage 10-outputs
CMOS Fanout Buffer with internal Crystal Oscillator. The XTAL
range is from 10MHz to 50MHz. The device has a wide range of
operating voltages of 2.5V and 3.3V. The device also provides user
selectable output VDD option, which provides excellent flexibilities
to users. This device is ideal for systems that need to distribute low
jitter clock signals to multiple destinations.
