Note
No.
Parameter
HB01 H-OUT pulse duty
TA1316AN
Test Method
(1) No signal input.
(2) Measure T1 and T2 (as shown in figure below) from pin 26 (H-OUT) output waveform when
sub-address (00) data is 80H and A0H. Determine duties TH_00A and TH_00B using the
following formula:
TH = T1/(T1 + T2) × 100 %
(3) Set sub-address (00) data to 81H, A1H, 82H and A2H, measure as in step (2) above, and
determine duties TH_01A, TH_01B, TH_10A and TH_10B.

HB02 Horizontal
free-running
frequency
(1) Set SW20 to open.
(2) Set sub-address (00) data to 00H and measure horizontal free-running frequency F00 from pin
26 (H-OUT) output waveform.
(3) Set sub-address (00) data to 40H, 80H and C0H, measure as in step (2) above, horizontal
free-running frequencies F01, F10 and F11.
HB03 Horizontal oscillation
frequency variable
range
(1) Set sub-address (00) data to 00H.
(2) Connect 10-kΩ resistor between pin 20 and V_CC. Measure horizontal frequency F00_MIN from
pin 26 (H-OUT) output waveform.
(3) Connect 68-kΩ resistor between pin 20 and GND. Measure horizontal frequency F00_MAX from
pin 26 (H-OUT) output waveform.
HB04 Horizontal oscillation
control sensitivity
(4) Set sub-address (00) data to 40H, 80H and C0H, and measure as in steps (2) and (3) above,
horizontal frequencies F01_MIN, F01_MAX, F10_MIN, F10_MAX, F11_MIN and F11_MAX.
(1) Set SW20 to open.
(2) Connect external power supply to TP20. Set sub-address (00) data to 00H.
Apply V₂₀ + 0.05 V and V₂₀ − 0.05 V (see HB01) to TP20, and measure frequencies FA and
FB from pin 26 (H-OUT) output waveform. Calculate frequency change rate (BH00) using the
following formula.
(3) Set sub-address (00) data to 40H, 80H and C0H, measure as in step (2) above, and calculate
frequency change rates BH01, BH10 and BH11.
HB05 H-OUT output voltage (1) Set SW20 to open.
(2) Measure high (V15_H) and low (V15_L) voltages of pin 26 (H-OUT) output waveform.
