SY100EL14V  
FEATURES  
DESCRIPTION  
The SY100EL14V 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 EL14V is  
suitable for operation in systems operating from 3.3V to  
5.0V supplies. 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 0.01µF capacitor. The VBB  
output is designed to act as the switching reference for  
the input of the EL14V under single-ended input  
conditions, as a result this pin can only source/sink up to  
0.5mA of current.  
3.3V and 5V power supply options  
Typical 30ps output-to-output skew  
Max. 50ps output-to-output skew  
Synchronous enable/disable  
Multiplexed clock input  
75Kinternal input pull-down resistors  
Available in 20-pin SOIC package  
The EL14V 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 pull-down 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.  
When both differential inputs are left open, CLK input  
will pull down to VEE and CLK input will bias around  
VCC/2.
