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.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.

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.
