5V ECL 1:6 Differential Clock Distribution Chip

The MC100E211 MC10E211 is a low skew 1:6 fanout device designed explicitly for low skew Clock Distribution applications. The E211 features a multiplexed Clock input to allow for the distribution of a lower speed scan or test Clock along with the high speed system Clock When LOW (or left open in which case it will be pulled LOW by the input pulldown resistor) the SEL pin will select the differential Clock input. Both a common enable and individual output enables are provided. When asserted the positive output will go LOW on the next negative transition of the CLK (or SCLK) input. The enabling function is synchronous so that the outputs will only be enabled/disabled when the outputs are already in the LOW state. In this way the problem of runt pulse generation during the disable operation is avoided. Note that the internal flip flop is clocked on the falling edge of the input Clock edge, therefore all associated specifications are referenced to the negative edge of the CLK input. The output transitions of the E211 are faster than the standard ECLinPS edge rates. This feature provides a means of distributing higher frequency signals than capable with the E111 device. Because of these edge rates and the tight skew limits guaranteed in the specification, there are certain termination guidelines which must be followed. For more details on the recommended termination schemes please refer to the applications information section of this data heet. 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 F capacitor and limit current sourcing or sinking to 0.5 mA. When not used, VBB should be left open. The 100 Series contains temperature co
