Application-specific integrated circuit (asic) for use in transmission devices of a digital network

摘要

The present invention relates to an application-specific integrated circuit (1) (application specific integrated circuit - asic) for use in transmission devices of a digital network, in which a data signal to be transmitted are divided into transmission frame. In order to prevent such a semiconductor circuit (1) in such a way that on external shown for function testing of the semiconductor circuit (1) can be dispensed with, the invention proposes that the semiconductor circuit (1) a circuit (4) to the embodiment of the asic - functions and a data test circuit (3) comprising first means (5) for generating a test signal, which is divided into transmission frame (6) and with second means (7) for the detection of bits - errors in a received test signal (8) comprises.
