I need help setting up this to an N factor of 1000. I am trying to lay this chip out on a PCB. I have the manufacturer data sheets, but I don't understand them.
Any help would be great.

Never used the part myself but it doesn't look too hard....
This looks like one way...
N=One Thousand choose Mode=10 (eg Ka=1, Kb=1,Kc=0)
N/Mode=One Hundred so try with
J4-J1=0
J8-J5=0 J12-J9=0 J16-J13=1 (eg 0x0001)
To verify
N= 10 x (1000x0 + 100x1 + 10x0 + 1x0) + 0 = 10 x (0+100+0+0) +0 = 10 x 100 = 1000
Sorry if I've mixed up my indians :-)
I was curious about this IC, so I bought one to play with.
I am not great at the Varification on this chip, but I built up the circuit as you have written it below. Checking it out with my signal generator, with an input of 100,000 hz it has an output of 7 hz. Not the 100 hz as expected.
I Determined that for Mode Select 10: Pin 14, Ka = 1 Pin 15, Kb = 1 Pin 11, Kc = 0
Pin 3, J1 = 1 Pin 10, J13 = 1
And all other Jams = 0
For a Normal high pulse output, Pin 2, Latch should = 0
With this connection and 100 Khz in, I get 100 Hz out.
Now can Someone Varify this with the math?
Take care.........Gary
