BCM7218X数据手册Broadcom中文资料规格书

描述 Description

The BCM7218X is the world’s first single-chip, Ultra High-Definition TV (UHDTV) SoC with AV1 support and integrated Wi-Fi 6 (IEEE 802.11ax), designed for satellite, cable and IPTV set-top box (STB) applications. The SoC incorporates full HDR 10-bit native decode and display, Broadcom's industry-leading advanced programmable luminance mapping (PLM) system, highest-performance advanced graphics processing, and leading 1-Gbit+ Wi-Fi 6 connectivity for wired and wireless networks.
The integrated Wi-Fi 6 WLAN subsystem (802.11 MAC/baseband/radio) can operate in both 2.4-GHz and 5-GHz modes. The SoC also includes an integrated Bluetooth 5 core supporting 2X longer range and 4X higher data throughput. The multi-codec decode and display systems enable the BCM7218X to support a 4K×2Kp60 client/PVR STB with  unique multi stream concurrent picture-in-picture (PIP). The PLM system allows for seamless and highest video quality SDR-to-HDR and HDR-to-SDR video conversion with the concurrent blending of graphics.
