I'm looking to use an IR link in an upcoming project and found that Vishay has 
3 OK priced receiver modules: TSOP36236TR, TSOP6236TR, TSOP36238TR - 36kHz and 
38kHz.

Does anyone have anything good or bad to say about them?

It's going to be exposed to sunlight in an outdoor environment. It won't 
receive in that environment, but I'm concerned about its output starting to go 
from the 'noise'. I used to have a TV that would come on at a certain time in 
the pm everyday in a certain month when sunlight hit it. Which would be better, 
36 kHz or 38? Also, are these things matched to particular IR LEDs or is the 
optical bandwidth wide enough on all IR LEDs that any will do?

At $2 ea, are there better-cheaper ones I should consider? The signal won't be 
standard, but custom and kept simple - some simple pulse train for on/off. 
False triggering from being near a window or such needs to be avoided, also in 
a simple manner.

Thanks in advance,
