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 specialist knowledge of complex protocols.



Orange Tree's proprietary GigExpedite chip ("GigEx") is a TCP/IP Offload Engine (TOE) that handles all the Ethernet communications protocols. This leaves the user device completely free for the user's application, and means the user doesn't have to know anything about Ethernet protocols. With the main processing engine implemented in TOE hardware, sustained data rates over 100MBytes/sec are achieved. You can read more about GigEx here

The module's small form factor (30mm x 25mm), low power consumption (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 applications, or simply as a convenient way to add connectivity to lower bandwidth systems.

Support for real-time applications includes Precision Time Protocol (IEEE1588 PTP) and Synchronous Ethernet (SyncE). PTP synchronises networked devices together providing a high resolution 'time of day' 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 slave 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 available 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.
