IT9500 ccHDtv trasmitter
- IT9500 is a series of highly integrated transmitter for ccHDtv camera
- The core of IT9500 is a DVB-T COFDM modulator.
- forward error correction coding
- digital modulation
- D/A IQ converter
- embedded USB 2.0 interface, and serial/parallel TS interface input/output with built-in de-multiplexer
- compliant to the non-hierarchical transmission specified in DVB-T (ETSI EN 300 744)

- digital video port (DVP) parallel output interface
IT9130: ccHDtv Receiver
- ccHDtv single-chip receiver consisting of high quality RF tuner front-end and COFDM demodulator
- It does not require external SAW filter, LNA, or Balun. IT9130 requires only one power regulator and one crystal to further simplify the system design and reduce the system cost
