7.4.13 Demodulator
The MT5135AE provides a high performance DVB-T and
DVB-C demodulation function, the integrated CI+ controller
and interface also reduce the complexity of TS routing.
Overall Features:
• Integrated DVB-T and DVB-C demodulators.
• Integrated CI/CI+ controller and interface.
• On-chip integrated SAW filter function.
• 10-Bit ADC accepting IF or low-IF inputs.
• RSSI measurement.
• Independent RF and IF AGC controls.
• One parallel or serial TS interface accepting output.

7.4.16 GAMMA
IC U7010 saves gamma data and V-COM data, the data
depends on the panel. The gamma data can be auto written
3 times by code initially. It is written via special tooling in the
factory via CN7000. V-COM data will be adjusted to nominal
values before shipping.
