Note
No.
Parameter
HA05 HD 1/2 input
threshold voltage
TA1316AN
Test Method
(1) Set sub-address (00) data to 40H.
(2) Input signal b (as shown in figure below) to TP16.
(3) Increase signal b amplitude from 0 V_P-P. When pin 26 (H-OUT) phase locks with that of signal
b, determine signal b amplitude V_thHD1.
(4) Input signal b (as shown in figure below) to TP13 and set sub-address (00) data to 41H.
(5) Measure as in step (3) above, and determine signal amplitude V_thHD2.

phase adjustment
variable range
(1) Set sub-address (00) data to 40H.
(2) Input signal b (as shown in figure below) to TP16.
(3) Change sub-address (01) data from 80H to 00H and measure pin 26 (H-OUT) waveform
phase change ∆H_SFT−.
(4) Change sub-address (01) data from 80H to FEH and measure pin 26 (H-OUT) waveform
phase change ∆H_SFT+.
