MaxLinear Introduces new transimpedance amplifier

MaxLinear Inc. (NYSE: MXL), a provider of radio frequency (RF), has introduced the MxL9162, a 64Gbaud linear coherent transimpedance amplifier (TIA) for next-generation 400Gbps/600Gbps dense wave division multiplexing (DWDM) coherent systems, the company said.

The MxL9162 features best-in-class RF system performance including over 40GHz channel bandwidth, low total harmonic distortion (THD), input referred noise density, power dissipation and channel crosstalk. The device exceeds the high-performance requirements of next-generation 64Gbaud high bandwidth (HB) micro-intradyne coherent receiver (ICR) designs for long-haul, metro and datacenter interconnect applications.

The MxL9162 is a dual-channel TIA with a per-channel data rate of 64Gbaud. Its excellent THD and optimal channel signal-to-noise-ratio enable a higher order of signal modulation such as 64-QAM that is required to support 400Gbps/600Gbps single wavelength data rates. An integrated photo detector bias and SPI interface with integrated high-resolution DAC/ADC greatly simplifies the peripheral circuit design, reduces module bill-of-material cost and minimizes substrate real estate. Ultra-low input referred noise density and low power consumption make it the best option for next-generation HB micro-ICR designs.
