BW9972 is a 20Gbps 4-lane linear redriver. It is compliant with UHBR20 (DP2.1 20Gbps), UHBR13.5 (DP2.1 13.5Gbps), UHBR10 (DP2.1 10Gbps), HBR3 (DP1.4 8.1Gbps), HBR2 (DP1.2 5.4Gbps), HBR (DP1.1 2.7Gbps) and RBR (DP1.0 1.62Gbps) and eDP 1.5 specification. BW9972 provides adjustable equalizer, flat gain controller to compensate for the channel loss, and extends the length and enables the systems to pass DisplayPort compliance. The device optimizes performance when DisplayPort signals travel across PCB and cables, signal integrity degrades due to loss and inter-symbol interference.
BW9972 offers single supply voltage 3.3V with ultra-low power consumption. Each channel operates independently. The advanced power management of BW9972 can consume ultra-low power when the channel is in low power state.
