... General Description The SL2305 is a low skew, low jitter Zero Delay Buffer with very low operating current. The product includes an on-chip high performance PLL that locks into the input reference clock and produces nine (9) output clock drivers tracking the input reference clock for systems requiring clock distribution ...
