The DisplayPort transmitter PHY version 1.4 can transmit data at rates between 1.62Gbps (RBR) to 5.4Gbps (HBR2). Common-mode biassing of the CDR bandwidth, the regulator voltage, the BGR voltage, and the terminator resistance are among the programmable analogue features. Other features include an integrated equaliser, 100 ohm termination resistors, and built-in equaliser. Support power supplies of 1.8V/0.9V for PLL testing and internal analogue signal monitoring.
