DS8627/DS8628 130/225 MHz Low Power Prescalers  
General Description  
The DS8627 and DS8628 are low power fixed ratio prescal-  
ers which divide by 24 and 20, respectively. The inputs can  
be driven either single or double-ended and they are buff-  
ered, providing 40/100 mVrms input sensitivity. The output  
provided is open-collector and is capable of interfacing with  
TTL and CMOS.  
separately or in conjunction with a phase-locked loop, and it  
can extend the useful range of many inexpensive frequency  
counters to 225 MHz.  
Features  
Y
Input frequency: 130 MHz (-4, -3); 225 mHz (-2, std)  
The device can be used in phase-locked loop applications  
such as FM radio or other communications bands to pre-  
scale the input frequency down to a more usable level. A  
digital frequency display system can also be derived  
Y
Low power: 10 mA (-4, -2); 7 mA (-3, std)  
Y
Input sensitivity: 100 mVrms (-4, -3); 40 mVrms (-2, std)
