PI6C10806B  
1.8V/2.5V/3.3V, 100MHz, Low Skew 1:6 Crystal to LVCMOS Clock Buffer  
Features  
Description  
• Six low skew outputs: < 80ps  
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.  
• Crystal oscillator input: 10MHz to 50MHz  
• Switching frequency up to 100 MHz  
• Fast output rise/fall time: < 800ps  
• 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)  
PI6C10806Bhasawiderangeofoperatingvoltages: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

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.

Application Notes  
Crystal circuit connection  
The following diagram shows PI6C10806B crystal circuit connection with a parallel crystal. For the C =18pF  
L
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.
