STDP2500 Mobility DisplayPort (MyDP) to DisplayPort converter

The STDP2500 is a Mobility DisplayPort to standard DisplayPort converter that facilitates streaming FHD 60 Hz video and audio from MyDP enabled smart phones and tablets to monitors and TVs with DisplayPort 1.1a compliant inputs. The STDP2500 is a VESA Mobility DisplayPort (MyDP) standard compliant device, implementing a single lane DisplayPort receiver and AUX_HPD. The output port comprises a standard DisplayPort 1.2 compliant transmitter with four main lanes, AUX channel, and HPD signal. The MyDP standard is a digital audio-video interconnect based on the VESA DisplayPort standard for a mobile source device capable of streaming uncompressed audio and video. It uses the existing standard 5-pin connector commonly used for charging the portable mobile devices to stream the audio-video to an external display.

The STDP2500 uses ST's latest generation DisplayPort receiver technology that supports a single AV stream at HBR2 speed, a data rate of 5.4 Gbps per lane. The DisplayPort output in STDP2500 is a four lane differential output capable of operating either at HBR2, HBR, or RBR data rate. This device can convert audio-video streams received from the MyDP source on a single lane input at HBR2 data rate (5.4 Gbps) into two lanes output at HBR rate (2.7 Gbps), or four lane output at RBR rate (1.62 Gbps). It can deliver 1080p 60 Hz video with a color depth of 24 bits per pixel and audio up to 8-channel at 192 Kb sample rate from a MyDP source to DisplayPort 1.1a based monitors. DisplayPort 1.2 compliant monitors are capable of receiving MyDP input directly through a passive cable. STDP2500 complies with the HDCP 1.3 content protection scheme with an embedded key option for secure transmission of premium digital AV content. It can also act as an HDCP repeater for the downstream sink when used in a dongle application.

The AUX_HPD is a single-ended sideband channel that assists in low-speed data exchange between the MyDP source and STDP2500. The AUX_HPD message handling is mapped to the corresponding AUX channel message and HPD signal at the output port for the downstream sink. The AUX_HPD data transfer rate is 1 Mbps, which is quite adequate for handling I²C and IR protocols. The MyDP source also uses the AUX_HPD channel for the DPCD read-write access.

This device has an on-chip microcontroller with SPI and I²C host interfaces for system configuration purposes. The STDP2500 implements a sink detection and monitoring feature that automatically puts the device into low power operation whenever the sink is disconnected.

The STDP2500 based accessory (dongle) is powered from the downstream sink. In addition, DisplayPort 1.2 compliant sinks in general are capable of charging the mobile source
