4.4.2
The analog transmitter transforms the unipolar bit stream to ternary (alternate bipolar)
return to zero signals of the appropriate programmable shape. The unipolar data is
provided by the digital transmitter.

Similar to the receive line interface three different data types are supported:
• Ternary Signal
• Dual-rail data PCM(+), PCM(–) at multifunction ports XDOP/XDON with 50% or 100%
• Unipolar data on port XOID is transmitted either in NRZ (Non Return to Zero) with

This value refers to an ideal transformer without any parasitics. Any transformer resistance or other parasitic
resistances have to be taken into account when calculating the final value of the output serial resistors.
Single-rail data is converted into a ternary signal which is output on pins XL1 and XL2.
The HDB3 and AMI line code is employed. Selected by FMR0.XC1/0 and

ternary interface mode. Selected by FMR0.XC1/0 and LIM1.DRS = 1.

without (FMR3.CMI) preprocessed HDB3 coding to a fiber-optical interface. Clocking
off data is done with the rising edge of the transmit clock XCLK (2048 kHz) and with
a programmable polarity. Selection is done by FMR0.XC1 = 0 and LIM1.DRS = 1.
