Low-Voltage 1:10 Differential ECL/PECL/HSTL Clock Driver
The XC100EP111 is a low skew 1-to-10 differential driver, designed with clock distribution in mind. It accepts two clock sources into an input multiplexer. The ECL/PECL input signals can be either differential or single-ended if the VBB output is used. HSTL inputs can be used when the EP111 is operating under PECL conditions. The selected signal is fanned out to 10 identical differential outputs. * * * * * * * * 100ps Part-to-Part Skew 35ps Output-to-Output Skew Differential Design VBB Output Low Voltage VEE Range of -2.375 to -3.8V for ECL Low Voltage VCC Range of +2.375 to +3.8V for PECL and HSTL 75k Input Pulldown Resistors ECL/PECL Outputs

LOW-VOLTAGE 1:10 DIFFERENTIAL ECL/PECL/HSTL CLOCK DRIVER
The EP111 is specifically designed, modeled and produced with low skew as the key goal. Optimal design and layout serve to minimize gate-to-gate skew within a device, and empirical modeling is used to determine process control limits that ensure consistent tpd distributions 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 50, even if only one side is being used. In most applications, all ten differential pairs will be used and therefore terminated. In the case where fewer than ten 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 XC100EP111, as with most other ECL devices, can be operated from a positive VCC supply in PECL mode. This allows the EP111 to be used for high performance clock distribution in +3.3V or +2.5V systems. Designers can take advantage of the EP111'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 more information on using PECL, designers should refer to Motorola Application Note AN1406/D.
