MAX24101 15Gbps Octal Linear Equalizer General Description Benefits and Features The MAX24101 restores high-frequency signal level at 1Gbps to 15Gbps Linear EQ the decision-feedback equalizer (DFE) receiver for high- Increases High-Frequency Signal Level To Help Rx loss backplane and cable channels. This permits the DFE DFE Achieve BER Goals receiver to meet BER goals. At 15Gbps, the MAX24101 Lowe r Power, Lower Cost, And Smaller Board can operate in channels with FR4 and cable HF loss more Footprint Than CDR Solutions of than 30dB at 7.5GHz. The linear transfer function is transparent to Adaptive DFE equalizers, permitting DFE Transparent-to-Link Training, OOB And Idle adaptation to track temperature and changing channel Plug and PlaySet Control Pins (All Channels Set conditions. the Same) or Independent Control of Each Channel 2 Together with the DFE, integrated into Serializer/ through I C Bus Deserializer (SERDES), the device adds increased mar- 2 I C Daisy Chain For Addressing Up to 63 ICs gin rather than full signal regeneration.
