MaxLinear has released a dual-channel linear coherent transimpedance amplifier (TIA) for 100G/200G dense wave division multiplexing (DWDM) coherent systems.

The MxL9105 has a per-channel data rate of 32 Gbaud. Programmable channel bandwidth allows the receiver sensitivity to be optimized with photo detectors from a wide range of manufacturers. Ultra-low input referred noise density and extremely low power consumption make it ideal for the entire range of 32 GBd intradyne coherent receiver (ICR) module designs, including type 1, type 2 and the latest micro-ICR.

The TIA also has low total harmonic distortion (THD), channel crosstalk and high channel bandwidth and supports the low differential output swings required for next-generation low-power coherent DSPs. The high transimpedance gain is well-suited for metro networks that have greater signal loss, due to the prevalence of older fiber and multiple interconnects.

To minimize customer re-design and re-qualification efforts, the MxL9105's pin-out and functionality are compatible with legacy 32 GBd coherent TIAs.

Samples of the MxL9105 are available now. For more information, contact sales@maxlinear.com.
