ZestETM1低成本高性能千兆以太网TOE模块，板子支持 IPv4, UDP and TCP
ZestETM1 Gigabit Ethernet Module
The ZestETM1 is a low cost, compact module enabling high speed Gigabit Ethernet network connectivity in embedded devices. It acts as a bridge between a standard network port and familiar parallel and serial interfaces, offloading all networking tasks and allowing devices to communicate with the outside world without the need for spe***t knowledge of complex protocols.
Orange Tree&＃39;s proprietary GigExpedite chip ("GigEx") is a TCP/IP Offload Engine (TOE) that handles all the Ethernet communicati*** protocols. This le***es the user device completely free for the user&＃39;s application, and means the user doesn&＃39;t h***e to know anything about Ethernet protocols. With the main processing engine implemented in TOE ha***are, sustained data rates over 100MBytes/sec are achieved.
The module ***all form factor (30mm x 25mm), low power c***umption (less than 1.5W), and straightforward interfaces simplify integration into end user systems, while its high performance removes bottlenecks in transferring data to and from remote devices. Supporting sustained transfer rates of 100MBytes/second, it can be used both for high data rate applicati***, or simply as a convenient way to add connectivity to lower bandwidth systems.
Support for real-time applicati*** includes Precision Time Protocol (IEEE1588 PTP) and Synchronous Ethernet (SyncE). PTP synchronises networked devices together providing a high resolution &＃39;time of day&＃39; counter on each device. SyncE generates a synchronized 125MHz clock on all compatible devices.
The array of interfaces provided by ZestETM1 includes parallel registers, FIFO interfaces, SPI master and sl***e and UART ports, which simplifies connection to existing devices. A single power supply and low external component count minimise carrier board cost and area.
A breakout board is ***ailable to simplify evaluation of the module. The breakout board has an RJ45 connector and connects the user interface of the module to standard 0.1 inch connectors for easy connection to external devices.
