Voltage ECL/PECL 1:15 Clock Driver
MC100EP222 voltage, skew 1:15 differential ECL/PECL clock distribution buffer. MC100EP222 been designed optimized 2.5V 3.3V systems. Target applications this clock driver high performance clock distribution systems computer, networking telecommunication systems. Features: differential outputs output banks) selectable differential inputs Selectable frequency outputs device-to-device skew pin-to-pin skew Operates from -2.5, -3.3V (ECL) 2.5, 3.3V (PECL) power supply Extended temperature operating range information thermal characteristics impact operating life time refer AN1545, "Thermal data clock drivers" SUFFIX MC100EP222 device characteristics allows low-skew clock 52-LEAD LQFP PACKAGE distribution differential single-ended LVECL/LVPECL signals. Typical CASE 848D-03 applications MC100EP222 primary clock distribution systems telecommunication systems. MC100EP222 operated from 3.3V 2.5V positive supply (PECL mode) without requirement negative supply line. Each four output banks two, three, four differential clock output pairs independently configured distribute input frequency input frequency. FSELA, FSELB, FSELC, FSELD CLK_SEL asychronous control inputs. changes control inputs require pulse resynchronization outputs. functionality control input, "Timing Diagram" page Each CLK0, CLK1 inputs used differential single-ended. single-ended signals, connect bypassed output reference unused input pair. MC100EP222 guarantees output-to-output skew device-to-device skew max. ensure skew clock signals application, both sides differential output pair need terminated identically, even only side used. When fewer than fifteen pairs used, identical termination output pairs same package side recommended. outputs side used, recommended leave these outputs open unterminated. This will maintain minimum output skew.
