DisplayPort specialist, Parade Technologies, has two two new chips that expand options for video transport demultiplexing/multiplexing and signal conditioning for Dual-Mode DisplayPort 1.4 in personal computers, workstations, and other high-resolution video device applications. The PS8461 is a multiplexing, or “mux”, chip that allows the selection between one of two dual mode DisplayPort inputs that are jitter-cleaned and repeated at the output. The PS8469 is a demultiplexing, or “demux”, chip that allows a single Dual-Mode DisplayPort 1.4 input to be outputted either as a Dual-Mode DisplayPort 1.4 output or an HDMI 2.0b output, each being jitter-cleaned. Both devices support DisplayPort 1.4 HBR3 8.1Gbps and HDMI 2.0b 6Gbps data rates.
For systems supporting DisplayPort 1.4, the new PS8461 and PS8469 provide the platform designer a means to address the increasingly common need for multiple GPUs and/or additional video display and external connection options. The PS8461 2:1 mux is ideal for personal computer systems that utilize multiple GPUs, as it can be used to select which GPU will drive a video output connector or embedded display. The PS8461 can also be applied in displays or docking stations to select alternate video inputs.
The PS8469 is ideal for video devices that require both a DisplayPort output, including DisplayPort 1.4 with Dual-Mode support, and an HDMI 2.0b output. Example application video devices include personal computers and docking stations. The PS8469 accepts a single Dual-Mode DisplayPort 1.4 input and can provide either a repeated, jitter-cleaned, Dual Mode DisplayPort 1.4 compliant output from one output port, or a jitter-cleaned, level-shifted, HDMI 2.0b compliant output from another port.
The PS8461 and PS8469 implement configurable and automatic input equalizers to compensate for channel losses. The devices have a very low standby power consumption of less than 50 micro-watts.
The PS8461 and PS8469 devices are packaged in a 5x10mm 66-pin QFN which is RoHS compliant and halogen-free.
