+3.3V, 2.5Gbps Quad Transimpedance Amplifier  
for System Interconnects  
General Description  
Features  
The MAX3825 is a quad transimpedance amplifier (TIA)  
intended for 2.5Gbps system interconnect applications.  
Each of the four channels converts a small photodiode  
current to a measurable differential voltage with a tran-  
simpedance gain of 3.7k. The circuit features  
o Single +3.3V Supply  
o 93mW per Channel Power Dissipation  
o 460nA Input-Referred Noise  
RMS  
o 20ps Deterministic Jitter  
460nA  
of input-referred noise per channel corre-  
RMS  
o 2.4GHz Small-Signal Bandwidth  
o No External Compensation  
sponding to an optical input sensitivity of -22.3dBm  
(BER 1 × 10-14). The quad transimpedance amplifier  
has 20ps of deterministic jitter and a 2.4GHz small-sig-  
nal bandwidth. The MAX3825 is optimized for use with  
a quad PIN photodetector array with a standard fiber  
pitch of 250µm.  
o 40dB Power-Supply Rejection Ratio  
o Compact Die with 250µm Channel Pitch  
o 100Differential Output Impedance  
The MAX3825 operates from a single +3.3V supply  
over a 0°C to +85°C temperature range. With a +3.3V  
supply, each channel dissipates 93mW of power. A DC  
cancellation circuit on each channel provides a true dif-  
ferential output swing over a wide range of input cur-  
rents.
