TXD Transmit Data
RXD Receive Data
SD Shutdown
(Input, active high)
This CMOS input is used to transmit serial data when SD is low. An on-chip
protection circuit disables the IRED driver if the TX pin is asserted for longer than
100 s. When used in conjunction with the SD pin, this pin also provides control
signals to the internal digital serial control interface and legacy mode subsystems.
This input has an internal pull-down resistor that is disabled (open-circuited) dur-
ing shutdown. TXD has integrated digital AC coupling that prevents inadvertent
“always on” IREDs; therefore, no external AC coupling components are required
for input signals between GND and V
(Output, active low)
This output indicates received serial data. It is a push-pull CMOS driver capable of
driving a standard CMOS or TTL load. No external pull-up or pull-down resistor is
required.
(Input, active high)
This CMOS input pad functions as a shutdown switch and as a mode switch,
allowing bandwidth changes.
Shutdown and Legacy Mode Bandwidth Switching
Assertion of this pin high for a period of time exceeding 500 m places the module
into legacy shutdown mode, reducing current consumption to ~50 nA. On the fall-
ing edge of this signal, the state of the TX pin is sampled and used to set receiver
low bandwidth (TX = Low) or high bandwidth (TX = High) mode.
The transceiver powers on with the upper limit of the receiver bandwidth set to
1.152 Mbits/s operation. To set the bandwidth for operation at 4 Mbits/s, apply the
timings shown in Figure 3 to the SD and the TX inputs.
