Abracon ABB0205
The ABB0205 is a high performance, low skew, low jitter zero delay buffer designed to distribute high speed clocks and is available in 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.FEATURES

● Frequency range 25 ~ 60MHz. 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.

In that instance, a full power-up reset is required in order to reactivate the output clocks.
DESCRIPTION
Since the skew between the input and output is less than ± 350 ps, the device acts as a zero delay buffer. BLOCK DIAGRAM REF PLL CLKOUT CLK1 CLK2 CLK3 CLK4 30332 Esperanza., Rancho Santa Margarita, Ca 92688 Ph: 949-546-8000 Fax: 949-5...
