TP2857: The Next-Generation Automotive Quad HD Video Decoder.

1. Product Specifications
    Video Input: Supports 4-channel HD-TVI / CVBS / HD Analog video decoding, enabling a single chip to process full-surround imaging for the entire vehicle.
    Resolution Support: Supports up to 1080p @ 25/30fps, ensuring high-definition visual presentation.
    Output Interfaces:
    Equipped with a 4-lane MIPI-CSI2 output, supporting multi-channel Virtual ID transmission.
    Simultaneously supports DVP (Digital Video Port) parallel output, increasing flexibility for backend system integration.
    Package Size: QFN 68-pin  (8*8mm), offering a more compact footprint than the previous generation.

2. Applications
    Surround View Monitoring (SVM): 360-degree panoramic video decoding and seamless stitching applications.
    Advanced Driver Assistance Systems (ADAS): Rear-view or side-view blind spot detection video input.
    Mobile Digital Video Recorders (MDVR): High-definition multi-channel video recording for commercial vehicles, buses, or fleet management.
    Rear-view and Side-view Camera Modules: Replaces traditional analog video to enhance vehicle reversing and driving safety.

3. Key Advantages
    Built-in Diagnostics for Enhanced Safety:
    The TP2857 features unique STB (Short to Battery) and STG (Short to Ground) detection. It provides real-time monitoring for harness damage or abnormalities, which is critical for long-term stability in automotive environments, effectively preventing hardware damage and improving maintenance efficiency.
    Extreme Miniaturization and Cost-Effective Layout:
    Compared to its predecessor, the TP2857 reduces the package area and eliminates the 1.8V power requirement. This allows engineers to complete designs on smaller PCBs and reduces the cost of peripheral inductors and capacitors, making it ideal for space-constrained automotive cameras or head units.
    Superior Long-Distance Transmission and Noise Immunity:
    Featuring Techpoint’s leading Adaptive Equalizer (EQ) technology, the TP2857 maintains stable HD image quality even when using lower-cost thin coaxial cables or complex vehicle wiring. It effectively overcomes common automotive challenges such as electromagnetic interference (EMI) and signal attenuation.
