PI6C10806

1.8V/2.5V, 250MHz, Low Skew 1:6 Crystal to LVCMOS Clock Buffer

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 configured into 2 groups: a five 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

Features

• Six low skew outputs: < 80ps

• Crystal oscillator input: 10MHz to 40MHz

• Switching frequency up to 250 MHz

• Fast output rise/fall time: < 800ps

• Synchronous output enables

• Industrial Temperature range: –40°C to +85°C

• 1.8V and 2.5V operation

• Packaging (Pb-free & Green available):

– 16-pin 173-mil wide TSSOP (L)
