PAM4 clearly offers power, footprint and cost advantages because of the reduced number of transceivers compared to an identical NRZ solution (1/2 the number of TX/ RX).
In this paper, we propose the design of a track and hold (T&H) integrated circuit that is able to sample an incoming high-speed PAM4 signal and feed it to an analog to digital converter
Four-level pulse amplitude modulation (PAM4) uses four different signal levels for signal transmission, doubling the signal transmission efficiency compared with the traditional non-return-to

The PAM4 modulation format reduces the signal band- width by half and doubles spectral efficiency in com- parison to OOK signals. Therefore, PAM4 is expected to be an economical and efficient
PAM4 signaling has been widely adopted due to below described advantages: 1) Transistor and process node can be scaled to PAM4 baud rate; 2) Better SNR performance when the SERDES can support
We need to explore more efficient point-to-point transmission schemes, which can be used in fiber transmission and chip-level transmission. One of the
Building on the 50G PAM4 per lane technology, 400GE/200GE/ 50GE interfaces can meet the cost and performance requirements of 5G mobile networks to construct an optimal solution covering the
