20S62(TDVCF2016)
Tuner U101 outputs the IF signal and U102 is the SAWF.
After U102, the IF signal is send to P78 and P79 of LA76834.
LA76834 outputs the television signal at P56. After ceramic trap X4.5M, the CVBS signal of TV mode is formed.
The CVBS signal is send to P43(TV in) of MM1492.
MM1492 is controlled by M37762 through IIC bus. At TV mode, MM1492 obtains TV CVBS signal at P43 and outputs the
TV CVBS signal at P37(TV out).
The CVBS signal is send to P12 of TDA9183P.
After decoding, TDA9183P will send out the Y signal at P14 to P52 of LA76834 and C signal at P16 to P54 of LA76834.
(IF there are not TDA9183P, the CVBS signal is send to P52 of LA76834 directly. At the same time, the data in I703
should be changed. The comparison of with and without TDA9183P is as follows )

Sys.
LA76834 outputs H.SYNC signal at P37 and V.SYNC signal at P36. M37762 receives the SYNC signal and according to
the signal, it sends out RGB signal of OSD at P64\63\62 to P12\13\14 of LA76834.
LA76834 will mix the picture RGB and OSD RGB together and then sends out RGB signal at P17\18\19.
H.DRIVE signal is send out at P30 of LA76834.
V.DRIVE signal is send out at P26 of LA76834.
LA76834 sends out SIF(second sound IF) signal at P67. At the same time, it will get the SIF signal in itself.
LA76834 outputs the mono sound signal at P75.
The signal is connected to P42/43 of MM1492.
