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 an.
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 will provide near zero delay through the device. The PLL_En, Ref_Sel and the Test_Clk input pins provide a means of bypassing the PLL and driving the output buffers directly. This allows the user to single step a design during system debug. Note that the Test_Clk input is routed through the dividers s.
