描述 Description

The MxL9364x is a highly integrated PAM4 DSP SoC that enables 400Gbps optical interconnects using 100Gbps over a single optical wavelength (100G/λ).

The device has a high-speed electrical interface with eight transmit (Tx) and receive (Rx) input/output (I/O) that connect electrically through a module connector to the host ASIC. The device also has a high-speed optical side interface that has four Tx and Rx I/O connecting through the optical components to optical fibers.

The electrical interface supports 106.25Gbps PAM4 signaling per lane over C2M host channels. The optical interface supports 106.25Gbps PAM4 signaling per wavelength for DR, FR, and LR applications.

The device supports DSP functions including Line-side Tx digital pre-distortion (DPD), transmit pre-emphasis (TX FIR), receiver feed forward equalization (FFE) and decision feedback equalization (DFE).

The MxL9364x, in a 12mm × 12mm package, includes integrated TOSA drivers with differential and single ended options for both SiPh and EML implementations. It offers exceptional signal integrity for 112G signals in a compact footprint suitable for next generation optical module form-factors such as QSFP-DD and OSFP.
