  VME Interface Card ECL to LVDS
VME Interface Card ECL to RS422/LVDS



  Unique product for VME users. Multi-function card provides many features.

The VME Interface Card provides two sets of interfaces and can generate test patterns, which can be substituted for normal interface throughput. All I/O is handled through the front panel:

1. Differential (RS422 or RS644 [LVDS]), serial Data and Clock inputs are converted to AMI serial data.

2. (9) differential ECL inputs are output as (9) differential data lines at ECL, PECL, RS422 or RS644 levels. Front panel LED's indicate signal activity on each input as well as verification of the status of the power supply voltages. All selectable parameters and characteristics are programmed by user applied jumpers configured at board level. An on board test generator, with user configurable data rate and data pattern provides verification of the operation of the output drivers and also allows the unit to function as a test signal source.
