NB4L52  
2.5 V/3.3 V/5.0 V Differential  
Data/Clock D Flip−Flop  
with Reset  
MultiLevel Inputs to LVPECL Translator  
w/ Internal Termination  
http://onsemi.com  
The NB4L52 is a differential Data and Clock D flipflop with a  
differential asynchronous Reset. The differential inputs incorporate  
internal 50 W termination resistors and will accept PECL, LVPECL,  
LVCMOS, LVTTL, CML, or LVDS logic levels. When Clock  
transitions from Low to High, Data will be transferred to the  
differential LVPECL outputs. The differential Clock inputs allow the  
NB4L52 to also be used as a negative edge triggered device. The  
device is housed in a small 3x3 mm 16 pin QFN package.
