MC100SX1230 Features

* ide, a PLL is required to synthesize the 2X coder clock and a conditioning circuit is needed at the output of the coder to generate the appropriate signal to drive the cable. Device Operation The circuit contains a complete CMI coder and decoder as well as the support circuitry necessary to perform
