Infrared protocol-based infrared code transmission circuit, chip, remote control device and air conditioner

摘要

Provided are an infrared protocol-based infrared code transmission circuit, a chip, a remote control device and an air conditioner. The infrared code transmission circuit includes: a carrier duration control module; a processing module that is configured to configure the carrier duration control module according to a stage type of an infrared code to be transmitted in an infrared protocol, so that the carrier duration control module generates an enabling signal; a carrier generation module that is provided to generate a PWM-type carrier signal according to the stage type of the infrared code to be transmitted in the infrared protocol, and carry out a logic operation on the PWM-type carrier signal and the enabling signal to generate and transmit the infrared code to be transmitted.
