Signal Name:
Signal Description:
Signal Type:
Updated on the rising edge of TCLKO with the bipolar data out of the transmit-side formatter. Can be programmed
to source NRZ data by the output data format (IOCR1.0) control bit. This pin is normally connected to TPOSI.
Signal Name:
Signal Description:
Signal Type:
Updated on the rising edge of TCLKO with the bipolar data out of the transmit-side formatter. This pin is normally
connected to TNEGI.
Signal Name:
Signal Description:
Signal Type:
Buffered clock that is used to clock data through the transmit-side formatter (i.e., either TCLK or RCLKI). This pin
is normally connected to TCLKI.
Signal Name:
Signal Description:
Signal Type:
Sampled on the falling edge of TCLKI for data to be transmitted out onto the T1 line. Can be internally connected
to TPOSO by connecting the LIUC pin high. TPOSI and TNEGI can be connected together in NRZ applications.
