[embodiment]
Below in conjunction with drawings and Examples panel TV set of the present invention is described further.
The signal flow graph of a kind of panel TV set provided by the invention as shown in Figure 3.The tuner that this panel TV set connects successively, sound table, UOCIII circuit, MST51X circuit and LCD/PDP screen.
This panel TV set operation principle is as follows:
TV signal is exported intermediate frequency by tuner, and through the sound table, the intermediate frequency amplifying unit that enters the UOCIII circuit carries out intermediate frequency and amplifies, video decode then, AV, S-VIDEO signal then are directly inputted to and carry out video decode in the UOCIII circuit, export rgb signal behind the video decode.

2(KCS) agreement is than traditional I for KCL, KDA for C
2C communication is reliable more, effective, makes UOCIII circuit and MST51X circuit constitute an organic system.
The KKLINK protocol of I
2Some features of C control bus:
Require the three-bus circuit: the sheet of serial data line KDA, a serial time clock line KCL and a serial selects KCS, and 8 one-way data transmission bit rate of serial can reach 400kbit/s under mode standard.One of characteristics of KKLINK agreement are unidirectional I
2The C bus, promptly UOCIII is main, MST51X is passive controlled.KDA, KCL and KCS are connected to positive supply voltage by a current source or pull-up resistor, and KDA, KCL were high level when bus was idle, and KCS is a low level.
1. initial conditions:
KCS is switched to high level by low level when KCL is high level, and KDA data direction position R/W (0) expression transmission is write (1) expression request msg and read, and this situation represents it is initial conditions.
2. stop condition:
When KCL was low level, KCS was switched to low level by high level, and the KDA line is switched to high level by low level, at this moment KCL also low level switch the expression stop condition to high level.
3. read and write data:
Data on the KDA line must be that high level period keeps stablizing at KCL and KCS, and the high or low level state of data wire only could change when the clock signal of KCL line is low level.
4. reply data:
Transfer of data must be with reply data, and transmitter discharges the KDA line during the clock pulse of replying, and receiver must drag down the KDA line and make it keep stable low level between the high period of this clock pulse.
