The MAS7838 is a single chip duplex synchronous to asynchronous converter. It converts asynchronous start stop characters to synchronous character format, with stop bit deletion when required as defined in the CCITT remendation V.14 (V.22). On the receiver channel the MAS7838 converts the ining synchronous data to asynchronous start stop character format with stop bit insertion when required as defined in the CCITT remendation V.14 (V.22).The MAS7838 implements the data modes for the synchronous interface as specified in the V.14 (V.22). The device can be configured to operate at any frequency to maximum device speed within the above mentioned modes.
