Abstract
A 32Gb/s/lane NRZ wireline transceiver for the cellular mobile interface has been implemented. The maximum data bandwidth is 64Gb/s downlink and 32Gb/s uplink which meets the bandwidth requirement of the next FR2 standard. The master-slave LDO regulation is used to supply the stable power at each transmitter and receiver that operates independently. The dedicated clock correction and the channel adaptation have been performed to satisfy the time margin of 0.28UI at bit error rate (BER) of 10−12.
