All functions required for ISDB-T demodulation and error correction are built into the TC90517.
The input signals to be supported are a low IF (intermediate frequency) signal and direct IF signal.
Baseband IQ signals can also be input.
The output signal is an MPEG-2 transport stream (TS) in serial format. Note that a TS in parallel format
can be output by setting registers.

Service Adjustments
CAUTION !
Do not attempt to adjust service adjustments not listed below otherwise it may cause loss of performance
and for correct operation.
rSetting the Initial data
This adjustment is controlled by the CPU (IC5501) through the IIC Bus Data Line in the chassis, and those
adjustment data are memorized the memory IC (IC5601, IC5602). Therefore, Main board or the memory
IC (IC5601, IC5602) is replaced, these data will be disappeared. Readjust should be made. Initial data is
provided in the CPU ROM, when the memory IC (IC5601, IC5602) is replaced with new one. CPU ROM
data is loaded into the memory. Initial data is provided to operating the monitor basically. For operating the
monitor quality performance, further adjustment is required following chassis electrical adjustment.
1. Enter the Service Mode, and select NVM Initial.
Enter the Service Mode.
Select "SPECIAL SET" by pressing ▲ or ▼ button, then press ENTER button to enter SPECIAL SET
menu.
With the menu, press ▲▼ buttons to select NVM Initial, then press ENTER button,
after NVM initial operation is finished, please exit the menu. Disconnect the AC power supply and reconnect
it, then all the data will return to factory default settings.
(Note: After executed reset function, ADC ADJUST and W/B ADJUST should be readjusted. Please
enter Service Mode to adjust data.)
2. Enter the Service Mode, and select ADC ADJUST / W/B ADJUST to adjust the data according
"Service Adjustment Data Table" on page 10.
rHow to enter the Service Mode. Please refer to page 9.
