Measurement methods
(1) Input a white signal with sync into Pin61.
(2) Increasing the Pin61 input amplitude, measure the
amplitude at which the Pin53 output is clipped, that is
"DR

".
(1) Input a 2T pulse with sync and PAL burst into Pin61.
(2) Set the BUS data so that Y DL is 0ns(011).Observe the
Pin53 output, measure the delay time between Pin61 and
Pin53, that is "t
YDELP
".
(3) Set the BUS data so that Y DL is –120ns(000). Observe the
Pin53 output, measure the delay time between Pin61 and
Pin53 that is t
YDEL-120
.
(4) Set the BUS data so that Y DL is +160ns(111). Observe the
Pin53 output, measure the delay time between Pin61 and
Pin53 that is t

(1) Input 1Vp-p white signal with sync into pin #61
(2) Measure the gain between pin#61 and pin #53 for its
picture (without sync) level. Gy1
(1) Input a 0.5V(p-p) sweep signal with sync into Pin61.
(2) Measure the frequency at which the output amplitude is
3dB down against the level of 100Hz, which is "FR

(1) Input a sine wave signal (CVBS, V0=0.5Vp-p, f0=4MHz)
into pin 61, connect pin 55 and 44 to GND through 0.1F
capacitor.
(2) Set the bit of “Video SW” to “01, V2”, and measure the
amplitude of 4MHz signal at pin 53, that is V1-2.
(3) Set the bit of “Video SW” to “00, V1” and measure the
amplitude of 4MHz signal at pin 53, that is V1.
(4) “C CVBS1_2” = 20*log (V1-2 / V1)
