LT1328
In situations where long range is not a requirement, a very
simple IR link can be made using unmodulated NRZ
(nonreturn to zero) data. The circuit is shown in Figure 5.
A BER (bit-error rate) transmitter and receiver was used to
test the data-link error rates for data rates of 375kbps.
Because the NRZ data can have long stretches of continu-
ous “1” data, the low frequency corner of the LT1328
photodiode receiver is set to 14Hz to prevent pulse-top
distortion.

To do this, make C1 4.7
F. This is the only change from
a standard IrDA-SIR receiver. A range of 24" (with a bit
error rate lower than 1 in 108) is achieved with no
additional processing beyond that provided by the LT1328.
A caution: when using unmodulated data, it is possible to
get a 100% duty cycle on the LED transmitter, so be sure
that the LED can handle this.
