MPC990 (MPC990 / MPC991) LOW VOLTAGE PLL CLOCK DRIVER

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Low Voltage PLL Clock Driver The MPC990/991 is a 3.3V compatible, PLL based ECL/PECL clock driver. The fully differential design ensures optimum skew and PLL jitter performance. The performance of the MPC990/991 makes the device ideal for Workstation, Mainframe Computer and Telecommunication applications. The MPC990 and MPC991 devices are identical except in the interface to the reference clock for the PLL. The MPC990 offers an on board crystal osc.

MPC990 Features

* an external differential ECL/PECL feedback to the PLL. This external feedback feature allows for the MPC991’s use as a “zero” delay buffer. The propagation delay between the input reference and the output is dependent on the input reference frequency. The selection of higher reference frequencies wi
