DESCRIPTION  
The DS2174 enhanced bit error rate tester (EBERT) is a software-programmable test-pattern generator,  
receiver, and analyzer capable of meeting the most stringent error-performance requirements of digital  
transmission facilities. It features bit-serial, nibble-parallel, and byte-parallel data interfaces, and  
generates and uniquely synchronizes to pseudorandom patterns of the form 2n - 1, where n can take on  
values from 1 to 32, and user-defined repetitive patterns of any length up to 512 octets.  
Note: Some revisions of this device may incorporate deviations from published specifications known as errata. Multiple  
revisions of any device may be simultaneously available through various sales channels. For information about device errata,
