1Gbps to 12.5Gbps  
Passive Equalizer for Backplanes and Cables  
MAX387  
General Description  
Features  
The MAX3787 is a 1Gbps to 12.5Gbps equalization  
network that compensates for transmission medium loss-  
es encountered with FR4 and cables. The equalization  
network is composed entirely of passive components  
and functions equally well for 8b/10b or scrambled sig-  
nals. It is packaged in a small 1.5mm x 1.5mm chip-  
scale package (UCSP™) that can be placed anywhere  
along the transmission medium to increase jitter margin  
for high-speed interconnects. Roughly the size of two  
0603 components, the MAX3787 easily provides place-  
ment and routing flexibility.

Coding Independent, 8b/10b or Scrambled  
Ordering Information  
At 8.5Gbps, the MAX3787 compensates for spans up to  
18in of FR4 and 7m of cable. At 12.5Gbps, the MAX3787  
compensates for spans up to 12in of FR4 and 3m of  
cable. Input and output impedance is 100Ω differential.  
The MAX3787 requires no power and operates over a  
-40°C to +125°C temperature range.
