SAA3008

INTEGRATED CIRCUITS DATA SHEET SAA3008 Infrared remote control transmitter (RECS 80 low voltage) Preliminary specification File under Integrated Circuits, IC02 December 1988 Philips Semiconductors Preliminary specification Infrared remote control transmitter (RECS 80 low voltage) GENERAL DESCRIPTION SAA3008 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 PACKAGE OUTLINES SAA3008P: 20-lead DIL; plastic (SOT146); SOT146-1; 1996 December 6.
