Product Summary
The PNX7860E is a media processor for high-performance multimedia applications that deal with high-quality video and audio. These applications can range from low-cost, dedicated systems such as video phones, video editing, digital television, security systems or set-top boxes to reprogrammable, multipurpose plug-in cards for personal computers. The PNX7860E easily implements popular multimedia standards such as MPEG-1 and MPEG-2, but its orientation around a powerful general-purpose CPU (called the DSPCPU) makes it capable of implementing a variety of multimedia algorithms, both open and proprietary. The PNX7860E is also easily configured in multiple processor configurations for very high-end applications.
Parametrics
PNX7860E absolute maximum ratings: (1)2.5-V core supply voltage: -0.5 to 3.5 V; (2)3.3-V I/O supply voltage: -0.5 to 4.6 V; (3)DC input voltage on all 5-V pins: -0.5 to VX+0.5 V 1; (4)DC input voltage on all 3.3-V pins: -0.5 to VCC+0.3 V; (5)Storage temperature range: -65 to 150 Deg. C; (6)Maximum case temperature range: 0 to 120 Deg. C; (7)Human Body Model Electrostatic handling for all pins: CLASS 1C; (8)Machine Model Electrostatic handling for all pins: CLASS A.
Features
PNX7860E features: (1)Lower core voltage for PNX1311 (2.2V core voltage) and therefore lower power consumption; (2)DSPCPU speed of up to 200 MHz; (3)SDRAM speed of up to 183 MHz; (4)Support for 256 Mbit SDRAM organized in x16. The REFRESH counter must be changed. Refer for in Chapter 12, "SDRAM Memory System" for details; (5)Support for 16- and 32-bit Main Memory Interface; (6)Simplified power supplies sequencing (see Section 1.9.4); (7)Additional mode where VI_DATA[9:8] in message passing mode are not affected by the VI_DVALID signal.
