Samsung Electronics 6-24
7.SII169CT100 (IC601) – TMDS RECEIVER <<>> Check when the input mode is DVI
(1) Verify that the proper power is supplied (3.3V)
(2) Validate that the POWER DOWN is HIGH (Pin 2).
(3) Validate that DVI input is normal.
(4) Validate that data output is normal.
R, G, B digital data outputs (RA601 ~ RA606), DVI_HSYNC (Pin 48), DVI_VSYNC (Pin 47), DVI_CLK
(Pin 44) and DVI_DE (Pin 46)
8. ASI510(IC803) – SCALER
(1) Verify that the proper power is supplied (3.3V, 1.8V) – Since it is a BGA IC, measure the power input
terminal, eitherR or C.
(2) Verify that the input/output between ASI510 and the MEMORY (IC801 & IC802) is normal.
(3) Verify that the output from FLI2310, AD9883 and SII169CT100 is delivered to ASI510 normally.
(Digital R, G, B, HSYNC, VSYNC, and CLK)
(4) Validate that data output is normal.
R, G, B digital data outputs (RA801 ~ RA806), SNI_HSYNC, SNI_VSYNC, and SNI_CLK

DNIe2 (IC1003) – PICTURE ENHANCER
(1) Verify that the proper power is supplied (3.3V, 1.8V).
(2) Validate that the pin RESET is LOW (Pin 74).
(3) Validate the output of I2C-BUS (Pins 1 & 2).
(4) Verify that the output from ASI510 is delivered to the DNIe normally.
(Digital R, G, B, HSYNC, VSYNC, and CLK)
(5) Validate that data output is normal.
R, G, B digital data outputs, OUT_HSYNC (Pin 10), OUT_VSYNC (Pin 9), and OUT_CLK (Pin 12)
10. DS90C385(IC1004) - LVDS TRANSMITTER
(1) Verify that the proper power is supplied (3.3V).
(2) Validate that the POWER DOWN pin (Pin 32) is HIGH.
(3) Verify that the output from the DNIe is delivered to DS90C385 normally.
(Digital R, G, B, HSYNC, VSYNC, and CLK)
(4) Validate that LVDS data output is normal.
