Features

a low voltage PECL input, in addition to its LVCMOS/LVTTL inputs, to allow it to be incorporated into larger clock trees which utilize low skew PECL devices (see the MC100LVE111 data sheet) in the lower branches of the tree. The fifteen outputs were designed and optimized to drive 50Ω series or parallel terminated transmission lines. With output to output skews of 300ps the MPC949 is an ideal clock distribution chip for synchronous systems www. DataSheet4U. com which need a tight level of skew fro.
