Key Features

  • to aid in system debug and test. The PECL reference input pins can be interfaced to a test signal and the PLL can be bypassed to allow the designer to drive the MPC992 outputs directly. This allows for single stepping in a system functional debug mode. In addition an overriding reset is provided which will force all of the Q outputs LOW upon assertion. The MPC992 is packaged in a 32.
  • lead TQFP package to optimize both performance and board density. MPC992 LOGIC.
