PI6C10806B 1.5V/1.8V/2.5V/3.3V, 160MHz, Low Skew 1:6 Crystal to LVCMOS Clock Buffer Features • • • • • • • • Description Six low skew outputs: < 80ps Crystal oscillator input: 10MHz to 50MHz Switching frequency up to 160 MHz 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 Block Diagram Pin Configuration 5 XTAL_IN BCLK[0:4] XTAL_OUT ENABLE1 Sync BCLK5 ENABLE2 1 16 XTAL_IN ENABLE2 2 15 ENABLE1 GND 3 14 BCLK5 BCLK0 4 13 VDDO VDDO 5 12 BCLK4 BCLK1 6 11 GND GND 7 10 BCLK3 BCLK2 8 9 Sync VDD Truth Table(1) Pin Description Pin Name Description ENABLE1, ENABLE2 Active High Output Enable Inputs XTAL_IN Crystal interface XTAL_OUT Crystal interface BCLK[0:5] Clock Outputs GND Ground VDD Core Power VDDO Output Power 13-0010 XTAL_OUT Inputs Outputs ENABLE1 ENABLE2 BCLK[0:4] BCLK5 L L L L L H L Switching H L Switching L H H Switching Switching Note: 1.
