FAQ

What video compression standards does the ASC8850ET/M2,551 support?

The ASC8850ET/M2,551 supports H.264 (Baseline, Main, and High Profiles with CABAC/CAVLC), MPEG-4 Simple Profile, and MJPEG Baseline. It achieves up to 1080p @ 45 fps H.264 encoding, 720p @ 30 fps MPEG-4, and 1080p @ 40 fps MJPEG - all with hardware acceleration to offload the ARM926EJ-S CPU. The ASC8850ET/M2,551 also enables SVC-T for temporal scalability and ROI encoding for bandwidth-efficient streaming.

Does the ASC8850ET/M2,551 include an integrated Ethernet PHY?

No, the ASC8850ET/M2,551 integrates only a 10/100/1000 Ethernet MAC with MII/GMII/RGMII interfaces; an external PHY is required for physical layer connectivity. This architecture allows designers to select PHYs with specific features such as Power over Ethernet (PoE) classification, extended temperature range, or low EMI emissions. The ASC8850ET/M2,551's MAC is fully compliant with IEEE 802.3 standards and supports standard MDIO/MDC management.

What is the maximum supported memory configuration for the ASC8850ET/M2,551?

The ASC8850ET/M2,551 supports two independent 16-bit DDR-II or DDR-III memory channels, each configurable up to 1 GB DDR-III @ 400 MHz or 512 MB DDR-II @ 333 MHz, for a total capacity of up to 2 GB. This dual-channel architecture delivers ≥6.4 GB/s peak bandwidth - sufficient for concurrent 1080p video encoding, image processing, and Linux OS operation. The ASC8850ET/M2,551 requires matched DIMMs or discrete chips with strict timing compliance per JEDEC specifications.

Can the ASC8850ET/M2,551 interface directly with CMOS image sensors?

Yes, the ASC8850ET/M2,551 supports direct connection to parallel-output CMOS image sensors via its 16-bit raw data interface (Bayer/CMYG) with pixel clock up to 180 MHz. It accepts 12–16-bit data widths and includes programmable sync signals (HSYNC/VSYNC), pixel clock gating, and data alignment logic. For CCD sensors, an external analog front-end is required. The ASC8850ET/M2,551 also supports BT.656, BT.1120, and HDMI input through dedicated video decoder interfaces.

Is the ASC8850ET/M2,551 pin-compatible with other members of the ASC885x family?

Yes, the ASC8850ET/M2,551 is pin-to-pin compatible with ASC8851ET/M2,551 and shares the same TFBGA-484 package and signal mapping. This allows hardware reuse across performance tiers - for example, upgrading from ASC8850ET/M2,551 to ASC8851ET/M2,551 requires only firmware and thermal design adjustments. However, ASC8850ET/M2,551 is not pin-compatible with ASC884x devices due to differences in memory bus width and peripheral signal allocation.
