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.
External PIN diode and transmit LED are required. A
control mode is provided to allow easy UART program-
ming of different modes.
The CS8130 operates from power supplies of +2.7V to
+5.5V.
