A novel high-speed transceiver based on 7 bit correlated non-return-to-zero(CNRZ-7) with high-bandwidth-density(bandwidth per unit length) and low-power for Die-to-Die(D2D) communication is proposed. In order to further improve the SNR and the bandwidth of the CNRZ-5 in D2D communication, a CNRZ-7 based transmitter matrix and receiver matrix are proposed firstly, which are derived from Walsh Hadamard(W-H) transform and inverse transformation. In addition, to reduce the power consumption of the transmitter, the encoding driver based on CNRZ-7 transmitter matrix is designed with source series terminated drivers(SST). To further improve the SNR of the receiver, the decoding circuit based on CNRZ-7 receiver matrix is designed with a special multi-input comparators(MIC), which contain equalizer circuits. This transceiver is designed with a 28nm CMOS technology and the core area is 0.66mm2. The post-simulation results show that this transceiver can operate at 280 Gb/s, and the data rate is 35 Gb/s/wire. The worst width of the receiver’s eye-diagrams is 0.45UI when the transceiver operates at a 50 mm PCB channel with a 10dB@20GHz insertion loss, and the total BER is less than 1E-15. The power consumption is 1.1pJ/b under a normal corner. |
