General Description
The MAX3945 is a +3.3V, multirate, low-power limiting amplifier optimized for
Fibre Channel and Ethernet transmission systems at data rates up to 11.3Gbps.
The high sensitivity limiting amplifier limits the signal generated by a
transimpedance amplifier into a CML-level differential output signal. All
differential inputs and outputs (I/O) are optimally back terminated for 50I
transmission line PCB design. The MAX3945’s dual-path limiting amplifier has
programmable filtering to optimize sensitivity for different data rates and to
suppress relaxation oscillations that could occur in some optical systems. The
MAX3945 incorporates two loss-of-signal (LOS) circuits and a programmable time
mask for the LOS output. A 3-wire digital interface reduces the pin count and
enables control of LOS threshold, LOS polarity, LOS mode, CML output level,
input offset correction, receive (Rx) polarity, Rx input filter, and Rx
deemphasis without the need for external components.
The MAX3945 is packaged in a 3mm x 3mm, 16-pin TQFN package.
