INDUSTRIAL TEMPERATURE RANGES
2.17.4 DUAL LOOPBACK
Dual Loopback mode is set by setting bit DLBn in register DLB and
bit RLBn in register RLB to ‘1’. In this configuration, after passing the
encoder, the data and clock to be transmitted are looped back to
decoder directly and output on RCLKn, RDn/RDPn and CVn/RDNn. The
recovered data from RTIPn and RRINGn are looped back to waveform
shaper through JA (if selected) and output on TTIPn and TRINGn. The
LOS Detector is still in use. Figure-18 shows the process.
2.17.5 TRANSMIT ALL ONES (TAOS)
In hardware mode, the TAOS mode is set by pulling pin TCLKn high
for more than 16 MCLK cycles. In host mode, TAOS mode is set by
programming register TAO. In addition, automatic TAOS signals are
inserted by setting register ATAO when Loss of Signal occurs. Note that
the TAOS generator adopts MCLK as a timing reference. In order to
assure that the output frequency is within specified limits, MCLK must
have the applicable stability.
The TAOS mode, the TAOS mode with Digital Loopback and the
TAOS mode with Analog Loopback are shown in Figure-19, Figure-20
