EL4585
Horizontal Genlock, 8FSC
The EL4585 is a PLL (Phase Lock Loop) sub-system,
designed for video applications and 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.
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 where
periodic disturbances are present in the reference video
timing such as VTR head switching. The lock detector output
indicates correct lock.
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 common video applications including 8FSC,
6FSC, 27MHz (CCIR 601 format) and square picture
elements used in some workstation graphics. To generate
4FSC, 3FSC, 13.5MHz (CCIR 601 format) etc., use the
EL4584, which does not have the additional divide-by-two
stage of the EL4585.
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.

NOTES:
1. 6FSC frequencies do not yield integer divisors.
2. CCIR 601 divisors yield 1440 pixels in the active portion of each
line for NTSC and PAL.
3. Square pixels format gives 640 pixels for NTSC and 768 pixels
for PAL.
4. Divisor does not include ÷ 2 block.

NOTES:
5. These Intersil Pb-free plastic packaged products employ special
Pb-free material sets, molding compounds/die attach materials,
and 100% matte tin plate plus anneal (e3 termination finish,
which is 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.
6. For 3FSC and 4FSC clock frequency operation, see EL4584
datasheet.
