FN7174.2

Horizontal Genlock, 4F

Features

• 36MHz, general purpose PLL

The EL4584 is a PLL (Phase Lock Loop) sub system,

designed for video applications but also suitable for general

purpose use up to 36MHz. In video applications, this device

generates a TTL/CMOS compatible Pixel Clock (CLK OUT)

which is a multiple of the TV horizontal scan rate and phase

locked to it.

• 4F based timing (use the EL4585 for 8F

)

• Compatible with EL4583 sync separator

• VCXO, Xtal, or LC tank oscillator

• < 2ns jitter (VCXO)

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 disturbances are present in the reference video

timing such as VTR head switching. The Lock detector

output indicates correct lock.

• User controlled PLL capture and lock

• Compatible with NTSC and PAL TV formats

• 8 pre-programmed TV scan rate clock divisors

• Selectable external divide for custom ratios

• Single 5V, low current operation

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

• Pb-Free plus anneal available (RoHS compliant)

Applications

• Pixel clock regeneration

selected for common video applications including 4F

3F , 13.5MHz (CCIR 601 format) and square picture

elements used in some workstation graphics. To generate

• Video compression engine (MPEG) clock generator

• Video capture or digitization

8F , 6F , 27MHz (CCIR 601 format) etc. use the

EL4585, which includes an additional divide-by-two stage.

• PIP (Picture in Picture) timing generator

• Text or graphics overlay timing

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.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material

sets; molding compounds/die attach materials and 100% matte tin plate

termination finish, which are RoHS compliant and compatible with both SnPb

and Pb-free soldering operations. Intersil Pb-free products are MSL classified

at Pb-free peak reflow temperatures that meet or exceed the Pb-free

requirements of IPC/JEDEC J STD-020.
