MOTOROLA SEMICONDUCTOR TECHNICAL DATA Low Voltage PECL PLL Clock Driver The MPC992 is a 3.3V compatible, PLL based PECL clock generator and distributor.

The fully differential design ensures optimum skew and PLL jitter performance.

The performance of the device makes the MPC992 ideal for workstations, main frame computer, telecommunication and instrumentation applications.

The device offers a crystal oscillator or a differential PECL reference clock input to provide flexibility in the referenc

MPC992 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 whi
