Na, it is a LMX2332, so not a MAX232 serial thingy.
It will divide my Rubidium 10 MHz reference by 10 to get 1 MHz,
and also divide a voltage controlled crystal oscillator at 24 MHz (or 25) to 1 MHz
and then compare the two 1 MHz signals
and use that to lock that crystal oscillator, making a Rubidium controlled 24 MHz (or 25).
That in turn will be the reference frequency for my LNB,
the 25 MHz (or 24) is then multiplied by 
For a 24 MHz xtal:
LO1 = 24 * 390 =  9360 MHz
LO2 = 24 * 426 = 10224 MHz
to form the local oscillator for the LNB down converter to receive the Eshail2 ham satellite
Eshail2:                        10498.675 MHz horizontal

Downlink:  
Narrow band     10489.55    to  10489.8 MHz
center          10489.675   MHz
Wide band       10491       to  10499   MHz
center          10495       MHz

resulting in a IF frequency of:

IF
LOW side        10489.55 - 9360 = 1129.55 MHz  1,129,550,000        in IF band      RTL-SDR lock
High side       10499    - 9360 = 1139   MHz   1,139,000,000        in IF band

start narrow band   10489.55   - 9360   = 1,129,550,000     Hz
center narrow band  10489.675  - 9360   = 1,129,675,000     Hz
end narrow band     10489.8    - 9360   = 1,129,800,000     Hz

start wideband      10491      - 9360   = 1,131,000,000     Hz
center wideband     10495      - 9360   = 1,135,000,000     Hz
end wide band       10499      - 9360   = 1,139,000,000     Hz

that then will be fed for narrow band into an RTL-SDR stick,
and for wideband into my PC satellite DTV card.

Or something like that.
Sat is not up there yet (I think, but spaceX already has it) so not in a hurry.

When PLL to 25 MHz I can just use it to view regular sat TV, in the picture above the original
25 MHz is glued to the side of the LNB to test if the modification did not kill it.
Very tricky to solder on that board, tracks just come off.
So there will be an external 24 MHz or 25 MHz reference input to that LNB, 2 cables to it.

At least that is the planning.
