The Data Rate in Transceiver mode is the same for both transmitter and receiver, unlike GTY which supports different Data rates for transmitter and receiver. GTM allows a PMA interface width of 64 bits for NRZ and 128 bit for PAM4 modulation. The supported data rates depend upon the speed grade. The maximum and minimum range are as follows:

  • Allowed data rates for PAM4 are 19.6 to 58.00 Gb/s
  • Allowed data rates for NRZ are 9.8 to 29.00 Gb/s

The GTM Transceiver Configuration Wizard can be used to create a GTM interface and the process of creating a GTM interface is similar to the process of creating the GTY and the GTH wizards.
