DS21455/DS21458 Quad T1/E1/J1 Transceivers
25.6 CMI (Code Mark Inversion) Option
The DS21455/DS21458 provide a CMI interface for connection to optical transports. This interface is a
unipolar 1T2B type of signal. Ones are encoded as either a logical one or zero level for the full duration
of the clock period. Zeros are encoded as a zero-to-one transition at the middle of the clock period.

DATA
CMI
Transmit and receive CMI is enabled via LIC4.7. When this register bit is set, the TTIP pin will output
CMI-coded data at normal levels. This signal can be used to directly drive an optical interface. When
CMI is enabled, the user can also use HDB3/B8ZS coding. When this register bit is set, the RTIP pin will
become a unipolar CMI input. The CMI signal will be processed to extract and align the clock with data.
