5 Gbps至6.4 Gbps收发器由并行12通道发射器（Tx）、12通道接收器（Rx）、基于LC-VCO PLL的时钟发生器和时钟恢复单元组成。Tx具有5抽头预加重滤波器，Rx具有带符号间干扰（ISI）监视器的均衡器。监视ISI使得能够对损耗补偿进行微调。Tx中的预加重滤波器和Rx中的均衡器可以分别补偿高达20 dB和15 dB的传输损耗（6.4 Gbps）。Tx和Rx通道（包括PLL）的面积均为3.92 mm/sup 2/。当补偿20 dB的损耗时，发射机在6.4 Gbps时消耗150 mW/信道，当补偿15 dB损耗时，接收机消耗90 mW/信道。
A 5 Gbps to 6.4 Gbps transceiver consists of a parallel 12-channel transmitter (Tx), 12-channel receiver (Rx), clock generators based on LC-VCO PLLs, and a clock recovery unit. The Tx has a 5-tap pre-emphasis filter, and the Rx has an equalizer with intersymbol interference (ISI) monitor. Monitoring the ISI enables a fine adjustment of the loss compensation. The pre-emphasis filter in the Tx and the equalizer in the Rx can compensate for a transmission loss of up to 20 dB and 15 dB at 6.4 Gbps, respectively. The areas of the Tx and Rx channels including the PLLs are both 3.92 mm/sup 2/. The transmitter dissipates 150 mW/channel at 6.4 Gbps when compensating for a loss of 20 dB, the receiver 90 mW/channel when compensating for 15 dB loss.
