M3004LAB1
REMOTE CONTROL TRASMITTER
GENERAL DESCRIPTION
The M3004LAB1/M3004LD transmitter IC are designed for infarared remote control systems.
It has a total of 448 commandswhich are divided into 7 sub-system groups with 64 commands each.
The sub-system groupswith 64 commands each. The su-system code my be selected by a press button, 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 infared flashes or modulated. The transmission mode is defined in conjuction with
the sub-system adress.Modulated pulses allow receivers with narrow-band preamplifiers for improved noise rejection
to be used. Flashed pulses require a wide-band preamplifier within the receiver.
