5 – 12

16.IC6951 (VHiYDA147SZ-1Y)

This is a digital amplifier. The 52” and 65” models are driven with 15W.

  AUDIO POWER AMPLIFIER

17.IC7103 (RH-iXC582WJQZQ)

This is an FPGA, which receives the 10-bit LVDS signal from IC6201, implements the color gamut conversion and skin color correction, and out-
puts via the 10-bit RGBs of LVTTL. Also, while the I2S signal is input from IC6102, it implements the audio delay processing for the delay of the
pictures generated on the LCD TCON+A3C and subsequent PWBs.

18.IC7502 (VHiTLVD1023-1Q)

This is an LVDS Tx, which converts the 10-bit RGBs of LVTTL from IC7103 into the LVDS signals.
