HSDL-7000 Datasheet, PDF (2/5 Pages) Agilent(Hewlett-Packard) – IR 3/16 Encode/Decode IC

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 V_CC. This
signal can also be used to disable
any data reception.
IR_RCV - A 3/16th pulse width
input signal from the HSDL-1000.
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 HSDL-1000.
V_CC - Power.
