M21170英文资料下载

　　The M21170 is a high-performance， 288x288， asynchronous non-blocking crosspoint switch featuring 82，944 unique switching paths. It is ideally suited for high-speed data switching in datacom， telecom， and video applications. Each switching path can operate independently at any data rate of up to 3.2 Gbps， allowing for multi-rate routing and switching in one single device. The M21170 includes per lane， programmable， input equalization and output de-emphasis， enabling optimal compensation for board trace losses and making the device ideal for designs in very large systems. To alleviate the power consumption and heat dissipation challenges in such systems， the output swing level for each lane may be set individually， providing flexibility and optimization of power dissipation without compromised performance. All unused output drivers， in addition to all paths not exercised within the device， are automatically disabled for maximum power savings. The device is configurable through standard 2-wire （I2C compatible） and 4-wire serial interfaces， as well as a 9-bit parallel interface.
