Details

[Mega Chip]DescriptionThe STDP4020 is a DisplayPort receiver IC for the reception of secure, high-bandwidth uncompressed digital audio-video signals targeted for applications such as DTV, LCD monitor, projector, and other types of display systems. STDP4020 is a VESA DP 1.1a and eDP compliant device, implementing a single link DisplayPort input port comprising four main lanes, auxiliary channel, and HPD. In addition to the standard HBR (2.7 Gbps) and RBR (1.62 Gbps) speeds, this device supports turbo speed of 3.24 Gbps per lane with a total link bandwidth of 12.96 Gbps. The higher bandwidth provides unique benefits to users over other commercial DP receivers for embedded applications by offering additional margin to support higher color depth, resolution, and refresh rate. For example, STDP4020 supports FHD nonreduced blanking video (1080p 30-bit color per pixel) at 120 Hz, plus 7.1 Ch audio for two-box TV applications.The advanced equalizer built in this device offers guaranteed performance over long reach cables. The auxiliary channel in STDP4020 acts as a bidirectional communication link, supporting application-specific protocols such as MCCS, DDC, UART, IR, as well as the dedicated DisplayPort link training and device management functions.Features• Enhanced DisplayPort® (DP) receiver – DP 1.1a compliant – Embedded DisplayPort (eDP) compliant – 1, 2, or 4 lanes• Higher bandwidth “Turbo mode” (3.24 Gbps per lane), supports: – 1920 x 1080 (FHD) 120 Hz/10-bit color video standard timings and 7.1 Ch audio – 2560 x 1600 (WQXGA), 2560 x 2048 (QSXGA) 60 Hz/10-bit color graphics and 7.1 Ch audio• Interface compatibility with wide range of display controller ICs – LVTTL (60 wide) and LVDS (quad bus) video interface – 8-Ch I2S and SPDIF audio interface• Robust AUX channel – Link service, maintenance – I2C-over-AUX (MCCS, DDC) – IR, full duplex UART protocol• Configurable through I2C host interface• Supports HDCP 1.3 with on-chip keys• HDCP repeater capability – Acts as upstream receiver• AUX to I2C bridge for EDID, MCCS pass through• Spread spectrum on DisplayPort, LVDS, and TTL interfaces for EMI reduction• Supports deep color and color format conversion – RGB/YUV (4:4:4) – 10-bit color – YUV (4:2:2/4:2:0) – 12-bit color – RGB (4:4:4) to YUV (4:4:4) conversion and vice-versa• Supports HBR/“Turbo” speed over HBR/RBR rated long cables (15 m and more)• Package – 164 LFBGA (12 x 12 mm / 0.8 mm)• Power supply voltages – 3.3 V I/O; 1.2 V coreApplications• Digital TV, LCD monitor, mobile display, projector, etc

FAQs

What is STDP8028?

The STDP8028 is a displayport dual-mode (DP++) switch designed by STMicroelectronics. It is suitable for applications requiring seamless connectivity between DisplayPort and HDMI interfaces, such as laptop docking stations, monitors, and multimedia devices.

How Does STDP8028 Work?

The STDP8028 functions as a dual-mode switch that supports both DisplayPort and HDMI signals. It enables automatic or manual selection between input ports, allowing flexible connection options for different devices. The switch maintains signal integrity and quality during the transition between DisplayPort and HDMI modes.

How Many Pins does STDP8028 have and What are the Functions of the Pinout Configuration?

The STDP8028 is housed in a 64-pin LQFP (Low-Profile Quad Flat Package) package. The pinout configuration includes:

  • IN1 to IN4: Input ports for DisplayPort or HDMI signals.
  • OUT: Output port for the selected input signal.
  • HPD: Hot Plug Detect pin for detecting connected devices.
  • EN: Enable pin for switching control.
  • DDC_SCL, DDC_SDA: Display Data Channel interface pins.
  • 5V: Power supply pin.
