Tunable linear ReDrivers support high levels of signal integrity

Diodes Incorporated has reinforced its large linear ReDriver IC portfolio through the introduction of two new 3.3V-rated multi-lane active demux devices. These advanced ReDrivers meet the demux demands now being set by the more graphically intense functions of mobile workstations, gaming PCs, and display dongles while also still fully optimised for the newest industrial computers and embedded systems hardware.

Supporting 13.5Gbps data rates, the four-lane PI3DPX8112 is applicable to DisplayPort 2.0 implementations (as well as earlier generations of the protocol). Besides this is the four-lane PI3HDX12212, which has 12Gbps performance capabilities that indicate it can manage HDMI 2.1, HDMI 2.0, HDMI 1.2, and HDMI 1.4 transmission modes.

Both ReDrivers provide pin strap adjustable eight-level receive equaliser settings on each of their two output paths, plus four settings for the adjusting of output flat gain and output swing parameters. Through these adjustments, it is feasible for the signal integrity to be tuned by specific application demands. Channel losses can then be compensated for, and ISI removed to aid in extending channel reach. These devices can take lower supply voltages than those attainable by the competition. They are protocol agnostic, transparent to channel link training and achieve ultra-low latency operation.

The devices are supplied in 32-pin TQFN packages (with 3mm x 6mm dimensions) that are extremely fitting for inclusion into space-limited environments. Both devices support a working temperature range of -40C to +85C.
