Transmitter
NRZ data arrives on TPOS and TNEG on the transmit system side. The TPOS and TNEG data is sampled on the
falling edge of TCLK.
The data is encoded with HDB3 or B8ZS or AMI encoding when single-rail mode is selected (only TPOS as the
data source). When in single-rail mode only, BPV errors can be inserted for test purposes by register BEIR. Pre-
encoded data is expected when dual-rail mode is selected. The encoded data passes through a jitter attenuator if it
is enabled for the transmit path. A digital sequencer and DAC are used to generate transmit waveforms compliant
with T1.102 and G.703 pulse masks.
The line driver supports internal impedance matching for 75
, 100, 110, and 120 modes.
The DS26334 drivers have short and open circuit driver fail monitor detection. There is an OE pin that can high
impedance the transmitter outputs for protection switching when low. The individual transmitters are by default in
high impedance. The OE register is used to enable the transmitters individually when the OE pin is high. The
DS26334 has to have the transmitter’s enabled by setting the register and then pulling the OE pin high. The
registers that control the transmitter operation are shown in Table 5-2.
