5 V ECL 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 0.01ĂmF
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.

NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
board with maintained transverse airflow greater than 500 lfpm. Electrical parameters are guaranteed only over the declared
operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit
values are applied individually under normal operating conditions and not valid simultaneously.
1. Input and output parameters vary 1:1 with VCC. VEE can vary +0.8 V / −0.5 V.
2. Outputs are terminated through a 50ĂW resistor to VCC − 2.0 V.
3. VIHCMR min varies 1:1 with VEE, VIHCMR max varies 1:1 with VCC. The VIHCMR range is referenced to the most positive side of the differential input
signal. Normal operation is obtained if the HIGH level falls within the specified range and the peak-to-peak voltage lies between VPPmin and 1 V.
