GENERAL 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.
APPLICATIONS

PIN CONFIGURATION
FEATURES
§ Generates and detects digital patterns for
analyzing and trouble-shooting digital
communications systems
§ Programmable polynomial length and
feedback taps for generation of any
pseudorandom patterns up to 232 - 1; up to
32 taps can be used in the feedback path
§ Programmable, user-defined pattern
registers for long repetitive patterns up to
512 bytes in length
§ Large 48-bit count and bit error count
registers
§ Software-programmable bit error insertion
§ Fully independent transmit and receive
paths
§ 8-bit parallel-control port
§ Detects polynomial test patterns in the
presence of bit error rates up to 10-2
§ Programmable for serial, 4-bit parallel, or
8-bit parallel data interfaces
§ Serial mode clock rate is 155MHz; byte
mode is 80MHz for a net 622Mbps; OC-3
§ Available in 44-pin PLCC
