DESCRIPTION

The M3004LD transmitter IC is designed for infra-

red 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 button, a slider

switch or hard wired.

The M3004LD generates the pattern for driving the

output stage. These patterns are pulse distance

coded. The pulses are infrared flashes or modulat-

ed. The transmission mode is defined in conjunc-

tion with the sub-system address. Modulated

pulses allow receivers with narrow-band preampli-

fiers for improved noise rejection to be used.

Flashed pulses require a wide-band preamplifier

within the receiver.
