STDP2530 HDMI to Mobility DisplayPort (MyDP) converter

The STDP2530 is a Mobility DisplayPort transmitter with an HDMI input that facilitates streaming FHD 60 Hz video and audio from MyDP enabled smart phones and tablets over a standard 5-pin connector. The STDP2530 is a VESA Mobility DisplayPort (MyDP) standard compliant device, implementing a single lane DisplayPort output and AUX_HPD signal. The input comprises an HDMI port with four differential signal pairs, CEC, 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 STDP2530 uses ST's latest generation DisplayPort transmitter technology that supports a single AV stream at HBR2 speed, a data rate of 5.4 Gbps per lane. The HDMI 1.4 receiver in STDP2530 is based on advanced high-speed TMDS technology supporting link rate up to 2.97 Gbps and the stereo 3D formats. In mobile applications, this device can receive up to 1080p 60 Hz video at 24 bits per pixel color and audio up to 8-channel at 192 Kb sample rate from the Application Processor Engine (APE) and converts into MyDP output over one lane for external display. This device also complies with the HDCP 1.3 content protection scheme with an embedded key option for secure transmission of premium digital AV content.

The AUX_HPD is a single-ended sideband channel used for low-speed data exchange with the MyDP converters or MyDP compliant sinks. The AUX_HPD data transfer rate is 1 Mbps, which is quite adequate for handling I²C and CEC protocols from the downstream sink. The AUX_HPD channel is also used for monitoring sink requests and DPCD read-write access.

The AUX-to-I²C translator in the STDP2530 bridges I²C communication between APE with the external display. Similarly, the AUX-to-CEC translator handles CEC message transfer from the sink to the APE. This device has an on-chip microcontroller with SPI and I²C host interfaces for system configuration purposes. The STDP2530 implements a sink detection and monitoring feature that automatically puts the device into low power operation whenever the sink is disconnected
