8. ributions from lot to lot The net result is a dependable guaranteed low skew device To ensure that the tight skew specification is met it is necessary that both sides of the differential output are terminated into 50Q even if only one side is being used In most applications all nine differential pairs will be used and therefore terminated In the case where fewer that nine pairs are used it is necessary to terminate at least the output pairs on the same package side as the pair s being used on that side in order to maintain minimum skew Failure to do this will result in small degradations of propagation delay on the order of 10 20ps of the output s being used which while not being catastrophic to most designs will mean a loss of skew margin The E111AE LE as with most other ECL devices can be operated from a positive Vcc supply in PECL mode This allows the E111AE LE to be used for high performance clock distribution in 5V 3 3V systems Designers can take advantage of the E111AE LE s performance to distribute low skew clocks across the backplane or the board In a PECL environment series or Thevenin line terminations are typically used as they require no additional power supplies For systems incorporating GTL parallel termination offers the lowest power by taking advantage of the 1 2V supply as terminating voltage Rev D Rev Date Amendment 0 October 1998 ClockWorks SY10E111AE LE Micrel SY100E111AE LE P
