Conserves Space and Power While Extending Reach in Channels Up to 15Gbps
The MAX24101 restores high-frequency signal level at decision-feedback equalizer (DFE) receiver for high-loss backplane and cable channels. This permits the DFE receiver to meet BER goals. At 15Gbps, the MAX24101 can operate in channels with FR4 and cable HF loss more of than 30dB at 7.5GHz. The linear transfer function is transparent to Adaptive DFE equalizers, permitting DFE adaptation to track temperature and changing channel conditions. Together with the DFE, integrated into Serializer/Deserializer (SERDES), the device adds increased margin rather than full signal regeneration. Unlike conventional equalizers with limiting output stages, the device preserves the linear channel characteristics, allowing the DFE to linearly operate over the entire channel. This permits extending total channel reach and/or improving signal-to-noise ratio (SNR). The device typically compensates for up to 19dB of the total loss in a long channel, effectively reducing the channel length seen by the DFE receiver. The device has 8 channels and is packaged in a space-saving, 4mm x 13mm, FCLGA package.
