The CS8130 is an infrared transceiver integrated circuit. The receive channel includes an on-chip, high-gain PIN diode amplifier; IrDA, HPSIR, ASK, and TV remote compatible decoder; and a data pulse stretcher. The transmit path includes IrDA, HPSIR, ASK, and TV remote compatible encoder with an LED driver. The computer data port operates from 1200 to 115200 baud and is standard UART TxD and RxD compatible. External PIN diode and transmit LED are required. A control mode is provided to allow easy UART programming of different modes. The CS8130 operates from power supplies of 2.7 to 5.5V.
