IR CONTROL IC
IR CONTROL
M3014
GENERAL DESCRIPTION
The M3014 is a remote control transmitter ASIC for TV, VTR , etc. 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.
FEATURES
Flashed or modulated transmission (default modulated mask option )
Flashed pulses require a wide band preamplifiers within the receiver
7 sub-system addresses
Up to 64 commands per sub-system address
Key release detection by toggle bits
A 455KHz ceramic resonator or crystal
APPLICATIONS
Audio equipment, TV, VTR, cassette desks etc..
