2.5V / 3.3V ECL ÷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 V
generated voltage supply, is available to this device only. For
single−ended input conditions, the unused differential input is
connected to V
rebias AC coupled inputs. When used, decouple V
0.01 mF capacitor and limit current sourcing or sinking to 0.5 mA.
When not used, V
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.
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 V
−3.0 V in NECL mode.
