The AN8918 is a highly integrated low power PAM4 DSP SoC, supporting 400GbE applications. It has eight lanes high-speed electrical interface to the host ASIC via a module connector, and also has eight lanes high-speed optical interface to fiber via optical components.

Equipped with re-timer and equalizer functions, the AN8918 retimes and equalizes a 53.125Gbps PAM4 and 26.5626/10.3125Gbps NRZ host side signal for 400GbE application, into corresponding line side signal.

For cost-effective and compact assemblies, the AN8918 has an optional embedded VCSEL driver with single-ended output to drive VCSEL directly for MMF link, it also supports differential output to interface with external laser diode driver.

With on-chip clock synthesis feature, the AN8918 can generate 156.25MHz clock internally for 400GbE applications by single 50MHz crystal oscillator.

This chipset is in a compact 11mmx11mm package footprint, suitable for next generation optical module applications.
