               APRIL 1995 SL490B 3056-1.3 REMOTE CONTROL TRANSMITTER (Supersedes version in April 1994 Consumer IC Handbook, HB3120 - 2.0) GPS has developed and produced a range of monolithic integrated circuits which give a wide variety of remote control facilities. As well as ultrasonic or infra-red transmission, cable, radio or telephone links may also be used. Pulse Position Modulation (PPM) is used with or without carrier and automatic error detection is incorporated. Initially designed with TV remote control in mind, the device is also suitable for use in radios, tuners, tape and record decks, lamps and lighting, toys and models, industrial control and monitoring. The SL490B is an easily extendable, 32-command PPM transmitter drawing negligible standby current.
