DESCRIPTION
The M3004LAB1/M3004LD transmitter IC are de-
signed for infrared remote control systems. It has
a total of 448 commands which are divided into 7
sub-system groups with 64 commands each. The
sub-system code may be selected by a press but-
ton, a slider switch or hard wired.
The M3004LAB1/M3004LD generate the pattern
for driving the output stage. These patterns are
pulse distance coded. The pulses are infrared
flashes or modulated. The transmission mode is
defined in conjunction with the sub-system ad-
dress. Modulated pulses allow receivers with nar-
row-band preamplifiers for improved noise
rejection to be used. Flashed pulses require a
wide-band preamplifier within the receiver.

Basic Unit of Pulse Distance
The following number of pulses may be selected by Metal option : N = 8, 12, 16.
Note : The different dividing ratio for TO and tW between flash mode and carrier mode is obtained by changing the modulo of a particular di-
vider from divide by 3 during flash mode to divide by 4 during carrier mode. This allows the use of a 600kHz ceramic resonator dur-
ing carrier mode to obtain a better noise immunity for the receiver without a significant change in TO and tW. For first samples, the
correct divider ration is obtained by a metal mask option. For final parts, this is automatically done together with the selection of
flash-/carrier mode.
