The SAA3008 transmitter IC is designed for infrared remote control systems. SAA3008 has a capacity for 1280 commands arranged in 20 sub-system address groups of 64 commands each. The subsystem address may be selected by press-button, slider switches or be hard-wired.
Commands are transmitted in patterns which are pulse distance coded. Modulated pulse transmissions allow a narrow-band receiver to be used for improved noise rejection. The modulation frequency of the SAA3008 is 38 kHz which is 1/12 of the oscillator frequency of 455 kHz (typical).
