Popis: A 28Gb/s NRZ wireline transceiver is implemented in 7nm FinFET. A transformer-based LC-PLL sends a single-phase differential clock to the voltage-mode transmitter and the receiver. Local multi-phase clocks are generated in each TX/RX lane to support digital phase interpolation. The receiver equalization consists of a single-stage CTLE that performs both high-frequency peaking and long-tail cancellation, a two-stage programmable gain amplifier, and a 15-tap DFE. The digital CDR achieves
