FUNCTIONAL DESCRIPTION

Generation of pulses

Generation of standard pulses such

as sync, blanking and burst for TV

systems: PAL B/G, PALN, PALM,

SECAM and NTSC. In addition a

number of non-standard pulses have

been supplied to simplify signal

processing. These signals include -

horizontal drive, vertical drive, clamp

pulse, identification etc. It is possible

to select the 524/624 line mode

instead of the 525/625 line mode for

all the above TV systems for

applications such as robotics, games

and computers.

DESCRIPTION

FSI

FSO

1 subcarrier oscillator input, where fmax = 5 MHz

2 subcarrier oscillator output

CS1

3 clock frequency selection - CMOS input

CS0

4 clock frequency selection - CMOS input

OSCI

5 clock oscillator input, where fmax = 24 MHz

OSCO 6 clock oscillator output

VLE

7 vertical in-lock enable - CMOS input

PH

8 phase detector output - 3-state output

LM1

9 lock mode selection - CMOS input

LM0

10 lock mode selection - CMOS input

ECS

11 external composite sync. signal - CMOS Schmitt-trigger

input

RR

12 frame reset - CMOS Schmitt-trigger input

SI

13 set identification, used to set the correct field sequence in

PAL-mode. The correction (inversion of fH2) is done at the

left-hand slope of the SI-pulse. Minimum pulse width is

800 ns. CMOS Schmitt-trigger input.

VSS

14 ground

ID

15 identification - push-pull output

BK

16 burst key (PAL/NTSC), chroma-blanking (SECAM) -

push-pull output

CB

22 horizontal drive pulse - push-pull output

NORM

23 used with X, Y and Z to select TV system; NORM = 0,

625/525 line mode (standard);

NORM = 1, 624/524 line mode - CMOS input

CLO

24 clock output - push-pull output

X

25 TV system selection input - CMOS input

Y

26 TV system selection input - CMOS input

Z

27 TV system selection input - CMOS input
