Infrared remote control transmitter

(RECS 80 low voltage)

Preliminary specification

SAA3008

GENERAL DESCRIPTION

The SAA3008 transmitter IC is designed for infrared remote control systems. It 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).

Features

• Modulated transmission

• Ceramic resonator controlled frequency

• Data-word-start with reference time of unique start pattern

• Supply voltage range 2 V to 6.5 V

• 40 mA output current capability

• Very low standby current (< 4 µA at VDD = 6 V)

• Up to 20 subsystem address groups; up to 1280 commands

• Up to 64 commands per subsystem address; up to 1280 commands

• Requires few additional components
