MAX3797
10.3Gbps, Low-Power Transimpedance Amplifier
for 10GBASE-SR Applications
General Description
The MAX3797 is a low-power transimpedance amplifier
designed for optical transmission systems at data rates
up to 10.3125Gbps and for use with PIN diodes.
The MAX3797 incorporates an automatic gain control
(AGC) architecture providing nominal small-signal trans-
impedance of 5.5kω. The input-referred noise is typi-
cally 1.25µARMS, which reflects a theoretical sensitivity
of –14.8dBm OMA at a bit error rate (BER) of 10-12 for a
PIN (þ = 0.55, re = 3) photo detector.
The small die size of 1mm x 0.76mm enables an opti-
cal subassembly using a TO-46 or TO-56 package. The
MAX3797 supports low-cost ROSAs by offering stable
operation with no capacitors required in the ROSA. The
MAX3797’s sensitivity is stable over temperature and
supply.
