Function
Pin Name
Output pin of the B or Cb signal of the image data. MSB is B/Cb7. Synchronizes with
DCLK. (Not used)
Dot clock (DCLK) signal pin. The DCLK frequency is normally 13.5MHz. The DCLK can
be input from this pin or can be made by frequency-dividing (1/integer) the clock input
from XTL0I.
+5V power supply
Ground
Horizontal sync signal pin. When using the built-in sync generator, a signal is made by
frequency-dividing the dot clock (DCLK). Serves as the input when not using the built-in
sync generator.
Vertical sync signal pin. When using the built-in sync generator, a signal is made by fre-
quency-dividing the DCLK. Serves as the input when not using the built-in sync generator.
Field determination signal. Odd field correspond to “H” and even field correspond to “L”.
Serves as an output when the built-in sync generator is used, and as an input when not.
/ Signal obtained by frequency-dividing the clock input from XTL0I or XTLI. When the
input clock is 8 fsc, it can be used as the horizontal sync signal phase comparison reference
signal.
Composite blanking signal pin. Serves as an output when the built-in sync generator is
used, and as an input when not. / Signal obtained by frequency-dividing the clock input
from XTL0I or XTLI. When the input clock is 8 fsc, it can be used as the fsc signal.
Composite sync signal pin. A signal is made by frequency-dividing the DCLK. Cannot be
input. (Not used)
Sync generator reset signal pin. The signal generator is initialized by setting this pin to “L”.
Outputs the frequency-divided clock of the clock input to XTL0I. The frequency dividing
ratio can be selected from 1/2, 1/4, and 1/8. (Not used)
Digital output (Not used)
Audio serial data output to Audio D/A converter (IC101)
LR clock output to Audio D/A converter (IC101)
Bit clock output to Audio D/A converter (IC101)
Input 384fs (16.9344MHz) or 768fs (33.8688MHz).
+5V power supply
Ground
CD-ROM decoder, audio decoder master clock. Input a clock to the XTL21 or connect an
oscillator between XTL2I and XTL2O. The recommended frequency is 45 MHz. This
clock is for the internal circuit. Does not synchronize with inputs and outputs.
+5V power supply
C2 pointer input (CXD2545Q)
LR clock input (CXD2545Q)
