The SY10/100E111AE/LE are low skew 1-to-9 differential drivers designed for clock distribution in mind. The SY10/ 100E111AE/LE's function and performance are similar to the popular SY10/100E111, with the improvement of lower jitter and the added feature of low voltage operation. It accepts one signal input, which can be either differential or single-ended if the VBB output is used. The signal is fanned out to 9 identical differential outputs. An enable input is also provided such that a logic HIGH disables the device by forcing all Q outputs LOW and all Q outputs HIGH. The E111AE/LE 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 50Ω, 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.
