Description
Pericom Semiconductor’s PI6C10806 is a low skew six output
crystal oscillator driver. Crystal oscillator input range is from
10MHz to 40MHz. If XTAL_IN is driven with a signal source,
then the input frequency can be as high as 250MHz. PI6C10806,
the outputs are confi gured into 2 groups: a fi ve output and a single
output; each with independent output enable.
PI6C10806 has a wide range of operating voltages: 1.8V and 2.5V.
This feature paired with the low output-to-output and part-to-part
skew makes the device ideal for low voltage, low power, high
frequency single ended applications; such as networking
