“…Recently, VI Systems demonstrated a single lane 200 Gbps high speed data transmission experiment with their fiber coupled test 850 nm VCSEL module over a distance of up to 100 meter [14]. Furthermore, to increase data rates to 224 Gbps, the use of a discrete multitone (DMT) transceiver is proposed [15]. VCSEL revenues for datacom are expected to exceed 2 BUSD in 2027 [16].…”

“…• Contribution 4: Publication of this research in order to further the state-of-the art, including a conference publication [3], a journal submission [4], and several patent submissions [5,6,7] Contribution 1 were described in Chapters 3 and 4, where time domain impulse response model was created from measured s-parameters of a sample transmission line, and used to simulate various SERDES and DMT systems. The transmission line model was used to simulate DMT systems to determine its theoretical validity, and determine an appropriate channel correction model.…”

High Data Rate DMT SERDES Design

The research presented in this thesis involves implementing a high data rate wireline communication system using Discrete Multitone (DMT) transmission. A theoretical analysis of the model of channels typically used for serializer/deserializer SERDES chip-to-chip communication is done, showing the benefits of DMT through improved spectral efficiency, and simplified transceiver design due to the pseudo-narrowband characteristics of DMT. Simulations results demonstrate this benefit by being able to achieve higher data rates than conventionally used non-return-to-zero (NRZ) and pulse-amplitude modulation (PAM) typically used, even with typical channel correction circuitry such as continuous-time linear equalizers (fs) and decision-feedback equalizers (DFEs). Furthermore, a combined bit-loading/power allocation and transmit side equalization algorithm is presented that can improve the data rate of the system and decrease its bit error rate. Measurement results are demonstrated using a digital-to-analog-converter (DAC) and analog-to-digital converter (ADC) test bed in realistic conditions for chip-to-chip communications with a data rate over 250 GB/s with a sufficient overhead for forward-error-correction (FEC) coding needed to reduce the bit-error rate (BER).
