Normally, the GTY transceiver analog voltage supplies have local power supply regulators that provide a final stage of voltage regulation. Preferably these regulators are placed as close as is feasible to the GTY transceiver power supply pins. Minimizing the distance between the analog voltage regulators and the GTY transceiver power supply pins reduces the opportunity for noise coupling into the supply after the regulator and for noise generated by current transients caused by load dynamics.
