Notes:
1. Tied through external series resistor, R1, to regulated Vled from 2.7 to 5.5V. Please refer to table
above for recommended series resistor value.
2. Internally connected to LED driver. Leave this pin unconnected.
3. This pin is used to transmit serial data when SD pin is low. If this pin is held high for longer than
50
μ
s, the LED is turned off. Do NOT float this pin.
4. This pin is capable of driving a standard CMOS or TTL load. No external pull-up or pull-down
resistor is required. The pin is in tri-state when the transceiver is in shutdown mode. The receiver
output echoes transmitted signal.
5. The transceiver is in shutdown mode if this pin is high for more than 400
μ
s. On falling edge of
this signal, the state of the TXD pin sampled and used to set receiver low bandwidth (TXD=low)
or high bandwidth (TXD=high) mode. Refer to the section ”Bandwidth selection timing” for
programming information. Do NOT float this pin.
6. Regulated, 2.7 to 3.6 Volts.
7. Connect to ASIC logic controller Vcc voltage or supply voltage. The voltage at this pin must be
equal to or less than supply voltage.
8. Connect to system ground.
9. Connect to system ground via a low inductance trace. For best performance, do not connect
directly to the transceiver pin GND.
10. CX1 must be placed within 0.7 cm of the HSDL-3220 to obtain optimum noise immunity.
11. In environments with noisy power supplies, including CX2, as shown in Figure 1, can enhance
supply ripple rejection performance.
