(the threshold of pin 23: 8.7 V = DEF VCC - 0.3 V) When Double Scan Mode, function of Pin 38 and 40 are changed. * Normal Scan (internal CP) Mode: Pin 41 H-out The function of Pin 40 is curve correction input, that of Pin 38 is FBP (flay back pulse) input. The input signals of Y2, U/I and V/I inputs (pin 1, 2 and 3), Analog OSD inputs (pin 18, 19 and 20), Analog RGB inputs (pin 22, 24 and 25) are clamped of the internal CP based on the Y1/Sync input (pin 52). * Double Scan (external CP input) Mode: Pin 41 H-out The function of Pin 40 is EXT/BPP (Note 2) input, that of Pin 38 is H/V BLK (blanking) input. The input signals of Y2, U/I and V/I inputs (pin 1, 78 and 80), Analog OSD inputs (pin 18, 19 and 20), Analog RGB inputs (pin 22, 24 and 25) are clamped of the external CP based on Pin 40.

After using the preset values to transmit the BUS control data, set ACB operation switching to ACB off (01). Ensure the composite signal is always input to pin 52 (Y1/sync input). Set the BUS control data to the preset value. Connect pin 78 to an external power supply (PS) and observe pin 2. Turn the Y mute off (1), turn the black stretch gain off (1), and set the black detect level to 0 IRE (1). Increase the PS voltage from 5 V and measure the DC differential VB of pin 3 where the picture period (high period) of pin 2 goes low. Set the black detect level to 3 IRE (0).

Turn the Y mute off (1), turn the black stretch gain off (1), and measure the amplitude VA of pin 3. Turn the black stretch gain on (0) and measure the amplitude VB of pin 3.

Connect pin 78 to an external power supply (PS), increase the voltage from V53, and plot the resulting change in voltage S1 of pin 3. Next, turn the black stretch gain on (0), set the black stretch point 1 to the minimum (000), increase the PS voltage from V53 as in 3), and plot the resulting change in voltage S2 of pin 3. Set the black stretch point 1 to the maximum (111), increase the PS voltage from V53 as in 3), and plot the change in voltage S3 of pin 3. Use the diagram below to calculate the intersections VBST1 and VBST2 of S1, S2, and S3. Use the following formulas to calculate PBST1 and PBST2. PBST1 [(IRE)] = ((VBST1 [V] - V49 [V] / 1.4 [V]) x 100 [(IRE)] PBST2 [(IRE)] = ((VBST2 [V] - V49 [V] / 1.4 [V]) x 100 [(IRE)] Pin V3 Black Stretch Start Point (1) C OFF A C S3 VBST2 S1 VBST1 S2 (asymptotic line) V49 Pin 37 2002-04-01 TA1276AFG Test Conditions (unless otherwise stated, VCC1 = 5 V, VCC2/VCC3/DEF VCC = 9 V, Ta = 25 3C) Note Parameter SW 15 Switching Mode Test Conditions SW 49 SW 50 SW 53 1) 2) Set the BUS control data to the preset value.

Turn the black stretch gain on (0), connect pin 3 to an external power supply (PS), and measure pin 11 (R OUT). When the black stretch start point 2 data are at the minimum (000), calculate as in the diagram the black stretch start point differential V000 for when P is V49 (APL 0%) and for when P is V49 + 1.0 [V] (APL 100%). Next, when the black stretch start point 2 data are maximum (111), calculate differential V111 in the same way. Calculate the following formulas.

Input a 60 Hz composite video signal to pin TP52, vary the vertical frequency of this signal in 0.5H-steps, and measure the number of Hs when D2 of the 1st byte changes from 1 to 0 in bus read mode when. Also check that D1 of the 1st byte is 0 when 1 V = 262.5H, D1 is 1 in bus read mode, and 1 V < 261.5 or 1 V > 263.5H.
