Fast output rise/fall time (down to 1.8V): < 800ps
Synchronous output enables
Industrial Temperature range: –40°C to +85°C
1.5V, 1.8V, 2.5V and 3.3V operation
Packaging (Pb-free & Green available):
– 16-pin 173-mil wide TSSOP (L)
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 160MHz. 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: 1.5V, 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
