EL4584C

Horizontal Genlock, 4 F

Features

# 36 MHz, general purpose PLL

General Description

The EL4584C is a PLL (Phase Lock Loop) sub system, designed

for video applications but also suitable for general purpose use

up to 36 MHz. In a video application this device generates a

TTL/CMOS compatible Pixel Clock (Clk Out) which is a multi-

ple of the TV Horizontal scan rate, and phase locked to it.

# 4 F based timing (use the

EL4585 for 8 F

)

# Compatible w/EL4583 Sync

Separator

# VCXO, Xtal, or LC tank

oscillator

The reference signal is a horizontal sync signal, TTL/CMOS

format, which can be easily derived from an analog composite

video signal with the EL4583 Sync Separator. An input signal

to ‘‘coast’’ is provided for applications were periodic distur-

bances are present in the reference video timing such as VTR

head switching. The Lock detector output indicates correct lock.

2 ns jitter (VCXO)

# User controlled PLL capture and

lock

# Compatible with NTSC and PAL

TV formats

The divider ratio is four ratios for NTSC and four similar ratios

for the PAL video timing standards, by external selection of

three control pins. These four ratios have been selected for com-

# 8 pre-programmed TV scan rate

clock divisors

mon video applications including 4 F , 3 F , 13.5 MHz

(CCIR 601 format) and square picture elements used in some

workstation graphics. To generate 8 F , 6 F , 27 MHz (CCIR

# Selectable external divide for

custom ratios

# Single 5V, low current operation

601 format) etc. use the EL4585, which includes an additional

divide by 2 stage.

Applications

# Pixel Clock regeneration

# Video compression engine

(MPEG) clock generator

For applications where these frequencies are inappropriate or

for general purpose PLL applications the internal divider can be

bypassed and an external divider chain used.

CCIR 601 Divisors yield 720 pixels in the portion of each line for NTSC and PAL.

Square pixels format gives 640 pixels for NTSC and 768 pixels for PAL in the active portion.

3Fsc numbers do not yield integer divisors.
