The Metrodata LV2000 is designed to enable the transmission of LAN frames over an EIA-644/LVDS connection. The LV2000 will operate with satellite modems offering LVDS interfaces, providing a low cost alternative to HSSI for operation at up to 52Mbps. The LV2000 will also operate with the latest generation of high speed crypto units which offer LVDS interfaces for operation at up to 52Mbps. The LV2000 offers an automatic transmit crypto resync function that will generate a resync request to the crypto if th LV2000 senses the data stream has lost synchronisation.

The LAN port of the LV2000 is a 10/100BaseT auto-sensing interface supporting an auto crossover connection and presented on an RJ45 connector. The unit’s operating mode is configured by setting bit-switches mounted on its base.

The LV2000 LVDS interface is presented as DTE and will operate at data rates up to 52Mbps maximum. The LV2000 will operate in a standard bi-directional, symmetric mode as well as uni-directional or asymmetric applications. The LVDS port complies with the electrical specification EIA-644.

To give maximum flexibility for connection to crypto units, the resync request signal may be active high or active low, and be presented as a balanced LVDS or unbalanced LVTTL signal
