The SAA3008 is an infrared remote control transmitter IC from Philips Semiconductors. It can transmit 1280 commands, each group of commands has 64 commands, and the subsystem address can be selected by buttons or switches. The commands are transmitted in patterns that are pulse distance coded. Modulated pulse transmissions allow a narrow-band receiver to be used for improved noise rejection.
The SAA3008 is an integrated circuit designed for infrared remote control systems, featuring a capacity for 1280 commands arranged in 20 sub-system address groups. It utilizes modulated pulse transmissions at a frequency of 38 kHz to allow for improved noise rejection in narrow-band receivers.
