The INAP560T / INAP590T is a high-speed digital multi-channel SerDes transmitter for infotainment applications. The highly scalable physical layer is APIX2 compatible and based on the APIX3 technology providing forward compatibility accordingly. It establishes a DC-balanced, AC coupled, low latency, point-to-point link over Star Quad (STQ) cables.

The INAP560T / INAP590T supports popular automotive displays with HD (High Definition) video resolutions up to 24 bit color depth. The device offers an HDMI 1.4 compliant video interface. Leveraging the HDMI 3D functionality, the device is able to receive and distinguish 2 independent video streams for transmission over the APIX2 link in point-to-point or daisy-chain applications.
The product version INAP590T supports High-bandwidth Digital Content Protection according to HDCP 1.4. It incorporates the encryption mechanisms as well as the required keys to transmit two independent streams of HDCP 1.4 encoded video and audio content over the APIX2 link.

In addition to the video transmission, the INAP560T / INAP590T provides independent full-duplex data communication channels. Using Inova's proprietary AShell protocol, secure data transfers are provided by error detection and automatic retransmission mechanisms. With its Media Independent Interfaces (MII/RMII), the INAP560T / INAP590T can directly connect to standard 100Mbit-Ethernet Media Access Controllers. Additionally, the link is optimized to carry low latency GPIO signals for reset or synchronization purposes. The built-in audio path allows synchronous TDM transmission of up to 8 audio channels, with accurate clock regeneration at the receiver for demanding infotainment applications. The high-speed serial driver can be pre-configured to adjust the characteristics of the physical layer to the transmission link and its specific PCB layout, cables and connectors.
