MN676011NPS
NTSC Color Camera Synchronizing Signal Generator LSI
Overview
The MN676011NPS is a CMOS LSI that generates
NTSC color camera synchronizing signals as defined by
the EIA RS-170A standard.
It features a built-in 4fSC (14.31818 MHz) crystal os-
cillator circuit and divides that frequency to generate the
horizontal synchronizing signal fH (15.7 kHz), the vertical
synchronizing signal fV (60 Hz), and the composite
synchronizing signal.
It also divides the 4fSC clock signal frequency by four
to generate the color subcarrier frequency signals SC1
and SC2 and the burst signal gated with the burst flag
(BF) pulse.
It includes a vertical reset (VR) input pin for resetting
the leading edge of the vertical synchronizing pulse (VP)
with the falling edge of the input signal. It also includes
separate clock input pins for the color subcarrier frequency
signal circuits and the synchronizing signal circuits to
permit synchronization with such external synchroniz-
ing LSIs as the MN6761S.
Features
Power-saving CMOS synchronizing signal generator
(conformed to EIA RS-170A standard)
Built-in 14.31818 MHz clock generator
12 signal outputs including horizontal and vertical
synchronizing signals and color subcarrier
frequency signals (The vertical synchronizing signal
is available as the VP signal output.)

Function Description
Color subcarrier frequency signal (3.58 MHz) formed by
dividing the crystal oscillator signal (4fSC) by four.
Color subcarrier frequency signal (3.58 MHz) formed by
dividing the crystal oscillator signal (4fSC) 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.
