DESCRIPTION

The M3005LAB1/M3005LD 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 M3005LAB1/M3005LD 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.
