General Description
The CS8130 is an infrared transceiver integrated cir-
cuit. The receive channel includes on-chip high gain
PIN diode amplifier, IrDA, HPSIR, ASK & TV remote
compatible decoder, and data pulse stretcher. The
transmit path includes IrDA, HPSIR, ASK & TV remote
compatible encoder, and LED driver. The computer
data port is standard UART TxD and RxD compatible,
and operates from 1200 to 115200 baud.
