Function Description
Color subcarrier frequency signal (3.58 MHz) formed by
dividing the crystal oscillator signal (4f_SC) by four.
Color subcarrier frequency signal (3.58 MHz) formed by
dividing the crystal oscillator signal (4f_SC) by four.
This signal lags SC1 by 90°.
Burst output signal
If SC1 is the 180° signal, BSC is the 0° signal.
Composite synchronizing signal
Vertical synchronizing signal output (width: 3H)
Wide HD signal
Preblanking signal with pulse width of 9.71 µs
Composite blanking signal
See the entries for SW1– SW4 for the pulse width.
Composite pulse for black level playback
Clamp pulses for luminance and color difference signals
Horizontal deflection start pulses
Composite wide blanking signal
This signal provides a horizontal blanking interval of
26.89 µs and a vertical blanking interval of 134.5H
Gate signal for color subcarrier frequencies
The pulse width is 2.51 µs with the vertical interval (9H)
dropped out.
