Pin Description
16XCLK - Positive edge
triggered input clock that is set to
16 times the data transmission
baud rate. The encode and
decode schemes require this
signal. The signal is usually tied
to a UART’s BAUDOUT signal.
TXD - Negative edge triggered
input signal; usually tied to a
UART’s SOUT signal (serial data
to be transmitted).
RCV - Output signal which is
usually tied to a UART’s SIN
signal (received serial data).
GND - Chip ground.
NRST - Active low signal used to
reset the decode state machine.
This signal can be tied to POR
(Power on reset) or VCC. This
signal can also be used to disable
any data reception.
IR_RCV - A 3/16th pulse width
input signal from the infrared
transceiver. The signal is a
demodulated (pulse stretched) to
generate the RCV output signal.
IR_TXD - This signal is the
modulated 3/16ths TXD signal
which is input to the infrared
transceiver.
VCC - Power.
