MC100LVEP34 2.5V / 3.3VECL ÷2, ÷4, ÷8 Clock Generation Chip The MC100LVEP34 is a low skew ÷2, ÷4, ÷8 clock generation chip designed explicitly for low skew clock generation applications. The internal dividers are synchronous to each other, therefore, the common output edges are all precisely aligned. 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 mF capacitor and limit current sourcing or sinking to 0.5 mA. When not used, VBB should be left open. The common enable (EN) is synchronous so that the internal dividers will only be enabled/disabled when the internal clock is already in the LOW state. This avoids any chance of generating a runt clock pulse on the internal clock when the device is enabled/disabled as can happen with an asynchronous control. An internal runt pulse could lead to losing synchronization between the internal divider stages. The internal enable flip−flop is clocked on the falling edge of the input clock; therefore, all associated specification limits are referenced to the negative edge of the clock input. Upon start−up, the internal flip−flops will attain a random state; the master reset (MR) input allows for the synchronization of the internal dividers, as well as multiple LVEP34s in a system. Single−ended CLK input operation is limited to a VCC ≥ 3.0 V in PECL mode, or VEE ≤ −3.0 V in NECL mode.

Internal Clock Disabled Internal Clock Enabled MR CLK Q0 Q1 Q2 EN CASE 2: If the MR is de−asserted (H−L), after the Clock has transitioned low, the outputs will follow the third ensuing clock rising edge. Figure 2. Timing Diagrams The EN signal will “freeze” the internal divider flip−flops on the first falling edge of CLK after its assertion. The internal divider flip−flops will maintain their state during the freeze. When EN is deasserted (LOW), and after the next falling edge of CLK, then the internal divider flip−flops will “unfreeze” and continue to their next state count with proper phase relationships.
