Low Skew Output Buffer
FEATURES
Frequency range 75 ~ 180MHz. Internal phase locked loop will allow spread spectrum modulation on reference clock to pass to the outputs (up to 100kHz SST modulation). Zero input - output delay. Less than 700 ps device - device skew. Less than 250 ps skew between outputs. Less than 150 ps cycle - cycle jitter. Output Enable function tri-state outputs. 3.3V operation. Available in 8-Pin 150mil SOIC GREEN package.

Remark
If REF clock is stopped for more than 10us after it has already been provided to the chip, and after power-up, the output clocks will disappear. In that instance, a full power-up reset is required in order to reactivate the output clocks.
DESCRIPTION
The PLL102-03 is a high performance, low skew, low jitter zero delay buffer designed to distribute high speed clocks and is available in an 8-pin SOIC package. It has four outputs that are synchronized with the input. The synchronization is established via CLKOUT feed back to the input of the PLL. Since the skew between the input and output is less than ± 350 ps, the device acts as a zero delay buffer.
