MPC992

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 reference clock interface. All of the control signals to the MPC992 are LVTTL compatible inputs. MPC992 LOW VOLTAGE PLL CLOCK DRIVER Fully Integrated PLL Output Frequency of up to 400MHz PECL Clock Inputs and Outputs Operates from a 3.3V VCC Supply Output Frequency Configurable 32 TQFP Packaging ±25ps Cycle–Cycle Jitter FA SUFFIX PLASTIC TQFP PACKAGE CASE 873A-02 The MPC992 offers two banks of outputs which can be configured into four different relationships. The output banks can be configured into 2:1, 3:1, 3:2 and 5:2 ratios to provide a wide variety of potential frequency outputs. In addition to these two banks of outputs a synchronization output is also offered. The SYNC output will provide information as to the time when the two output banks will transition positively in phase. This information can be important when the odd ratios are used as it provides for a baseline point in the system timing. The SYNC output will pulse high for one Qa clock period, centered on the r...
