Table 1. Input/Output Functional Description
Symbol RxD I/O Type Output Polarity Active Low Function 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. This output may switch indeterminately when the module is transmitting. This output pin is in tri-state mode when the module is in shutdown mode and during digital serial programming operations. RxD is high at initializaton. This CMOS input is used to transmit serial data when SD/ Mode is low. An on-chip protection circuit disables the LED driver if the TxDpin is asserted for longer than 60 s. When used in conjunction with the SD/ Mode pin. TxD is low at initializaton. Assertion of this pin high for a period of time exceeding 400 s places the module into shutdown mode. On the falling edge of this signal, the state of the TxDpin is sampled and used to set receiver low bandwidth (TxD= Low) or high bandwidth (TxD= High) mode. See Figures 7 and 8 for timings. SD is low at initializaton Connect to positive power supply (2.7 V to 5.25 V). Placement of a 1.0 F to 10.0 F decoupling ceramic capacitor as close as possible to the V CC pin is recommended. Connect to power supply ground. A solid ground plane is recommended. This pin could be connected to ground. This pin can be connected directly to VCC. No series resistor is required. LED cathode. Leave this pin unconnected. This pin may be monitored to determine the state of the LED.

The transceiver powers on with the receiver in low bandwidth mode. To enable high bandwidth mode, apply timings as shown in the figure 7, to the SD/ Mode and the TxD inputs. Note that the internal LED driver is disabled when SD/ Mode is active and is not enabled until the next rising edge of TxD. This ensures that the LED will not be active during bandwidth adjustment. It is recommended that the SD/ Mode pin be connected to GND if bandwidth adjustment and shutdown mode are not used. Setting the Receiver to High Bandwidth Mode (see Figure 4) 1. Set the SD/ Mode input to 'logic high'. 2. Set the TxD input to 'logic high'. Wait tsu 10 ns. 3. Set the SD/ Mode to 'logic low'. (This high-to-low transition latches the state of TxD, which determines the receiver bandwidth.)

4. After waiting th 10 ns, set the TxDinput to 'logic low'. The receiver is in high bandwidth mode within 200 s of the SD/ Mode rising edge or 10 ns after the SD/ Mode falling edge, whichever occurs later. Setting the Receiver to Low Bandwidth Mode (see Figure 4) 1. Set the SD/ Mode input to 'logic high'. 2. Ensure that the TxD input is at 'logic low'. Wait tsu 10 ns. 3. Set the SD/ Mode to 'logic low'. (This high-to-low transition latches the state of TxD, which determines the receiver bandwidth.) 4. Ensure that the TxD input remains low for th 10 ns. The receiver is in low bandwidth mode within 200 s of the SD/ Mode rising edge or 10 ns after the SD/ Mode falling edge, whichever occurs later.
