The ESX uses an advanced FPGA (Field Programmable Gate Array) that provides increased input/output channels, GPIO (General Purpose Input Output) control functions and signal processing capabilities. This "soft core" architecture allows each implementation to be tailored for a particular product, and lowers parts costs by enabling the ESX module to perform product-specific functions.
The ESX is based on a Xilinx Spartan(TM) 3 FPGA. In addition to its EtherSound duties, the Spartan 3 has an embedded microcontroller. The chip can be programmed via firmware to perform EQ, mixing and other audio processing. It provides scalable input/output schemes of up to 64 channels. Its extensive GPIO capabilities can be used for user interface and control of external circuits. An Asynchronous Serial I/O port receives serial control data over Ethernet.
As an Authorized Implementer, Lab X is qualified not only to sell the ESX Network I/O Module, but to provide engineering support to manufacturers who are seeking to develop new products or to migrate existing products to EtherSound.
