5VECL 1:4 Clock
Distribution Chip
The MC10EL/100EL15 is a low skew 1:4 clock distribution chip
designed explicitly for low skew clock distribution applications. 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 EL15 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 and pulled LOW by the
input pulldown resistor) the SEL pin will select the differential clock
input.
The common enable (EN) is synchronous so that the outputs will
only be enabled/disabled when they are already in the LOW state. This
avoids any chance of generating a runt clock pulse when the device is
enabled/disabled as can happen with an asynchronous control. The
internal 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.
The 100 series contains temperature compensation.

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.
