APPLICATIONS INFORMATION

There is one drawback to the previous scheme. Lowering
the highpass frequency to 14Hz negates the normally
excellent ambient light rejection of the LT1328 to line-
operated light sources. By modulating the data in a very
simple and inexpensive way the ambient light rejection
can be maintained. The NRZ data is used to gate a 3MHz
square wave before driving the transmitter. The LT1328 in
FIR-4ppm mode (bandwidth of 1MHz to 4MHz) will re-
ceive the 3MHz signal. Thus, the low frequency response
is no longer required and the LT1328 can be configured as
a FIR receiver with no changes. Note that when in FIR/
4ppm mode, the LT1328 has excellent rejection to active-
ballast fluorescent lights (40kHz to 100kHz) as well as line
operated bulbs. The data is recovered with two stages of
retriggerable one-shots on the output of the LT1328. The
first one-shot pulse length is set to 80ns and acts as an
edge detector and the second one-shot pulse length is set
to 2.3
s, just under a symbol period. With this modula-
tion, the range can be extended to over 30" and still have
a bit error rate lower than 1 in 108.
