1:5 Clock Distribution Chip

The MC100LVEL/100EL14 is a low skew 1:5 clock distribution chip

designed explicitly for low skew clock distribution applications. The
device can be driven by either a differential or single-ended ECL or, if
positive power supplies are used, PECL input signal. The LVEL14 is
functionally and pin compatible with the EL14 but is designed to operate
in ECL or PECL mode for a voltage supply range of 3.0V to 3.8V ( or
3.0V to 3.8V). If a single-ended input is to be used the VBB output should
be connected to the CLK input and bypassed to ground via a 0.01

capacitor. The VBB output is designed to act as the switching reference
for the input of the LVEL14 under single-ended input conditions, as a
result this pin can only source/sink up to 0.5mA of current.

The LVEL14 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.

1. This table replaces the three tables traditionally seen in ECL 100K data books. The same DC parameter values at VEE = 4.5V now apply across

the full VEE range of 3.0V to 5.5V. Outputs are terminated through a 50

resistor to 2.0V except where otherwise specified on the individual

data sheets.

1. Skews are specified for identical LOW-to-HIGH or HIGH-to-LOW transitions.
2. The CMR 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 1V. The lower end of the CMR range varies 1:1 with VEE. The

numbers in the spec table assume a nominal VEE = 3.3V. Note for PECL operation, the VCMR(min) will be fixed at 3.3V |VCMR(min)|.
