Low-Voltage Dual Differential ECL/PECL Clock Driver
MC100EP210 skew 1-to-5 dual differential driver, designed with clock distribution mind. input signals either differential single-ended output used. signal fanned identical differential outputs. 150ps Part-to-Part Skew typical 35ps Output-to-Output Skew typical Differential Design Output Voltage Temperature Compensated Outputs Voltage Range -2.25 -3.8V Input Pulldown Resistors EP210 specifically designed, modeled produced with skew goal. Optimal design layout serve minimize gate-to-gate skew within device, empirical modeling used determine process control limits that ensure consistent distributions from lot. result dependable, guaranteed skew device. ensure that tight skew specification necessary that both sides differential output terminated into even only side being used. most applications, differential pairs will used therefore terminated. case where fewer than pairs used, necessary terminate least output pairs same package side pair(s) being used that side, order maintain minimum skew. Failure this will result small degradations propagation delay order 10-20ps) output(s) being used which, while being catastrophic most designs, will mean loss skew margin.

LOW-VOLTAGE DUAL DIFFERENTIAL ECL/PECL CLOCK DRIVER
SUFFIX 32-LEAD LQFP PACKAGE CASE 873A-02
MC100EP210, with most other devices, operated from positive supply PECL mode. This allows EP210 used high performance clock distribution +3.3V +2.5V systems. Designers take advantage EP210's performance distribute skew clocks across backplane board. PECL environment, series Thevenin line terminations typically used they require additional power supplies. more information using PECL, designers should refer Motorola Application Note AN1406/D. MC100EP210 driven single-endedly utilizing bias output with CLKA CLKB input. single-ended signal used, should connected CLKA CLKB input bypassed ground 0.01 capacitor. output only source/sink 0.3mA; therefore, should used switching reference MC100EP210 only. Part-to-Part Skew specifications guaranteed when driving MC100EP210 single-endedly.
