Description
Pericom Semiconductor’s PI6C10806B is a low skew six output
crystal oscillator driver. Crystal oscillator input range is from
10MHz to 50MHz. If XTAL_IN is driven with a signal source,
then the input frequency can be as high as 100MHz. PI6C10806B,
the outputs are configured into 2 groups: a five output and a single
output; each with independent output enable.
PI6C10806B has a wide range of operating voltages: 1.8V, 2.5V, and
3.3V. 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
