Synchronous output enables
Industrial Temperature range: –40°C to +85°C
1.8V, 2.5V and 3.3V operation
– Mixed 3.3V core/2.5V output, 3.3V core/1.8V output, and
2.5V core/1.8V output operating voltages
• 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 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-topart skew makes the device ideal for low voltage, low power, high
frequency single ended applications; such as networking

Notes:
All parameters measured at ƒ=f MAX using a crystal input unless noted otherwise.
Outputs are terminated at 50Ω to VDDO /2.
1. XTAL_IN can be overdriven relatively to a signal a crystal provides.
2. Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at VDDO /2.
3. These parameters are guaranteed, but not tested.
4. This parameter is defined in accordance with JEDEC Standard 65.

crystal, it is suggested to use C1=15pF, C2=15pF. C1 and C2 can be adjusted to fine tune to the target ppm of
crystal oscillator according to different board layouts. R1 is not recommended.
