TC9590XBG(EL)

Overview

The TC9590XBG is an automotive-grade CMOS digital integrated circuit functioning as a bridge device that converts HDMI streams to MIPI CSI-2 TX. Designed for modern automotive application processors lacking native video streaming inputs, it accepts HDMI input and outputs a CSI-2 stream compatible with camcorder interfaces. The device supports HDMI 1.4a video formats up to 1080P @60fps and includes features such as HDCP support, EDID management, and audio processing via I2S or TDM interfaces.

Feature Summary

• HDMI-RX Interface: Supports HDMI 1.4a, video formats up to 1080P @60fps (RGB/YCbCr), internal Audio PLL, 3D support, and optional HDCP.
• CSI-2 TX Interface: MIPI CSI-2 compliant (Version 1.01), supporting up to 4 data lanes at 1 Gbps per lane for video, audio, and InfoFrame data.
• Audio Output: Multiplexed pins for either I2S (stereo) or TDM (8-channel) audio interfaces, supporting 16/18/20/24-bit data in Master Clock mode.
• System Control: Includes I2C slave interface (up to 2 MHz Ultra Fast-mode), NEC IR protocol support, and dual power domains (VDDC1 always on, VDDC2 shut-off in deep sleep).

Applications

• Automotive infotainment systems requiring HDMI-to-CSI-2 conversion
• Vehicle camera input modules utilizing Application Processors with CSI-2-only ports
• Digital cockpit displays integrating external HDMI sources

Procurement Notes

Verify the specific ordering suffix 'EL' against Toshiba Semiconductor and Storage documentation to confirm packaging details, as datasheets may not explicitly define suffix variations. Ensure compliance with AEC-Q100 Grade 3 qualification requirements (-40°C to 85°C ambient operating temperature) for automotive integration.

Selection Notes

Select this component when the target Application Processor lacks an HDMI input but provides a MIPI CSI-2 receiver. Confirm power supply compatibility with the required domains: 1.2V for core/MIPI D-PHY, 1.8V or 3.3V for I/O, 3.3V for HDMI, and 2.5V for APLL. Verify that the host system can accommodate the 64-LFBGA (7x7 mm) package dimensions.

Part Context

The TC9590XBG belongs to Toshiba's Automotive Peripheral Devices series. It addresses the architectural shift in automotive SoCs where dedicated video decoder ports are replaced by standard MIPI CSI-2 interfaces originally intended for camera sensors. This allows legacy HDMI sources to be processed by modern high-performance computing platforms.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative bridge devices based on MIPI CSI-2 output compatibility and HDMI 1.4a support if sourcing constraints exist.

FAQ

Does the TC9590XBG support Audio Return Channel (ARC)?

No, the device does not support Audio Return Path or HDMI Ethernet Channels.

What is the maximum video resolution supported?

The device supports video formats up to 1080P @60fps, including RGB and YCbCr444/422 at 24-bpp.

How is the audio data transmitted?

Audio is transmitted via multiplexed pins configured as either an I2S interface (single lane for stereo) or a TDM interface (fixed 8 channels). Both modes operate in Master Clock mode only.
