CM3107  
2 Amp Source/ Sink Bus Termination Regulator  
for DDR Memory and Front Side Bus Applications  
Features  
Product Description  
Ideal for Intel 865 Front Side Bus V and DDR  
The CM3107 is a sinking and sourcing regulator specif-  
ically designed for series-parallel bus termination for  
high-speed chip set busses as well as DDR memory  
systems. It can source and sink current up to 2.0A with

Lead-free versions available  
FSB mode, FSBSEL controls whether V is 1.225V or  
1.45V. This allows the same chip to be used in two dif-  
ferent circuits on an Intel 865-based motherboard.  
TT  
Applications  
The CM3107 provides over current and over tempera-  
ture protection, which protect the chip from excessive  
heating due to high current and high temperature. A  
shutdown capability using an external transistor  
reduces power consumption and provides a high  
impedance output.  
Intel 865/845 Front Side Bus termination  
Single and dual DDR memory termination  
Active termination buses  
Graphics card DDR memory termination  
The CM3107 is housed in 8-lead SOIC and PSOP  
packages and is available with optional lead-free finish-  
ing.
