PMP6577 is a complete power solution for the Xilinx 7-series GTX / GTH transceivers when mated to Xilinx MGT characterization boards. The AVCC at 1V up to 12A: AVTT at 1.2V up to 8A and AVCCAUX 1.8V at up to 2.6A (powered off 5V) are provided. For each output a TPS40400 controller with a dual NexFET is used. TPS40400 has PMBus interface to allow output voltage to be adjusted and current output to be monitored along with other functions. TLC555 timer used to synchronize all outputs to about 480kHz.
