... With the select input pulled HIGH, the TTL_CLK1 input will be selected. All of the control inputs are LVCMOS/LVTTL compatible. The MPC947 provides a synchronous output enable control to allow for starting and stopping of the output clocks. A logic high on the Sync_OE pin will enable all of the outputs. Because this control is synchronized to the input clock, potential output glitching or runt pulse generation is eliminated ...
