GTM is a high performance transceiver that supports PAM4 and NRZ modulations. GTM supports non- continuous data rates as given below.
- NRZ: 9.5 Gb/s to 29 Gb/s
- PAM4: 19 Gb/s to 112 Gb/s
Similar to GTY, Versal Adaptive SoC transceiver wizard supports 16 user configuration per lane for GTM.

Similar to GTY/GTYP, power is reported for any specific configuration depending on
CH*_TXRATE and CH*_RXRATE port connections. If
CH*_TXRATE and CH*_RXRATE are connected to some
logic other than GND/VCC, the configuration with worst case power among all
configurations is reported.
