Features and Applications
The MC100E111 is a low skew 1-to-9 differential driver, designed with clock distribution in mind. It accepts one signal input, which can be either differential or else single-ended if the VBB output is used. The signal is fanned out to 9 identical differential outputs. An enable input is also provided. A HIGH disables the device by forcing all Q outputs LOW and all Q outputs HIGH.
The device 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-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.
The lowest TPD delay time results from terminating only one output pair, and the greatest TPD delay time results from terminating all the output pairs. This shift is about 10 – 20 pS in TPD. The skew between any two output pairs within a device is typically about 25 nS. If other output pairs are not terminated, the lowest TPD delay time results from both output pairs and the skew is typically 25 nS. When all outputs are terminated, the greatest TPD (delay time) occurs and all outputs display about the same 10 – 20 pS increase in TPD, so the relative skew between any two output pairs remains about 25 nS. The VBB pin, an internally generated voltage supply, is available to this device only. For single-ended input conditions, the unused differential input is connected to VBB as a switching reference voltage. VBB may also rebias AC coupled inputs. When used, decouple VBB and VCC via a 0.01 µF capacitor and limit current sourcing or sinking to 0.5 mA. When not used, VBB should be left open. The 100 Series contains temperature compensation.
