JEDEC JESD8-30A

This standard defines the DC and AC single-ended (data) and differential (clock) operating conditions, I/O impedances, and the termination and calibration scheme for 1.25 V Pseudo Open Drain I/Os. The 1.25 V Pseudo Open Drain interface, also known as POD125, is primarily used to communicate with GDDR6 SGRAM devices.
