Method of Measurement of Electrical Characteristics

Video Block

2AGV1-4 video SW output level 1-4(CVBS1-4 input)

2AGVY1 video SW output level 1(Y input: Y/C)

2AGVY2 video SW output level 2(Y input: YCbCr)

1. Input SG.A to pin 46 (CVBS1), or pin 42 (CVBS2), or pin 38 (CVBS3), or pin 53 (CVBS4), or pin 51 (Y(Y/C)), or

pin 48 (Y(YCbCr)).

2. The amplitude (p-p) at pin 32 is measured.

* In order to select TV or external input, use the sub-addresses 0BH and 11H.

2AGVL1-4 video line SW output level 1-4(CVBS1-4 input)

2AGVYL1 video line SW output level 1(Y input: Y/C)

2AGVYL2 video line SW output level 2(Y input: YCbCr)

1. Input SG.A to pin 46 (CVBS1), or pin 42 (CVBS2), or pin 38 (CVBS3), or pin 53 (CVBS4), or pin 51 (Y(Y/C)), or

pin 48 (Y(YCbCr)).

2. The amplitude (p-p) at pin 60 is measured.

* In order to select TV or external input, use the sub-addresses 0BH, 11H, and 1F.

Y max maximum video output

1. Input SG.A to pin 46.

2. Measure the amplitude (p-p) other than the blanking part of the output of pins 14, 15, 16.

FBY video frequency characteristic

1. Input SG.B (800kHz, 5 MHz) to pin 46.

2. Measure the amplitude (p-p) other than the blanking part of the output of pins 14, 15, 16, take the results at 800 kHz

and 5 MHz as Vr1 and Vr2 respectively.

3. FBY is defined as follows.

CRF1 chroma trap attenuation 1 (normal R/G/B output)

TRF maximum chroma trap attenuation

1. Input SG.C to pin 46, measure the 3.58 MHz frequency level with TRAP ON/OFF (07H D3) DATA 1, take the

results to be N

2. Also measure the level with TRAP ON/OFF (07H D3) DATA 0.

3. CRF1 is defined as follows.

4. Take the minimum value of CRF1 when the I

2C BUS data of the TRAP fine ADJ (1DH D0/D1) is adjusted to be

TRF.
