Integrated Circuit
TV Horiz/Vert Countdown System Circuit
Description:
The NTE874 is a monolithic bipolar/I
2
L integrated circuit digital sync system designed for use in con-
sumer TV applications for color/monochrome receivers or monitors. This device takes the composite
video input signal in combination with the on–chip master–scan oscillator to provide both horizontal
drive and vertical deflection output signals.
Other on–chip functions include sync separator, horizontal APC, horizontal/vertical count–down cir-
cuitry, vertical ramp generator, and horizontal drive circuit (Pulse–Width Modulator).
The NTE874 features dual–mode operation and accepts either standard or non–standard video sig-
nals. An automatic mode–recognition system forces the operation into the asynchronous mode for
non–standard sync signals.
Intended for use with 525–line systems, the NTE874 is supplied in the 28–lead dual–in–line plastic
package.
