Notes:
1. Tied through external series resistor, R1, to regulated Vled from 2.4 to 5.5V. Please refer to table
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
4. This pin is capable of driving a standard CMOS or TTL load. No external pull-up or pull-down
5. The transceiver is in shutdown mode if this pin is high. Do NOT float this pin.
6. Regulated, 2.4 to 3.6 Volts.
7. Connect to ASIC logic controller Vcc voltage or supply voltage. The voltage at this pin must be
8. Connect to system ground.
9. Connect to system ground via a low inductance trace. For best performance, do not connect
10. CX1 must be placed within 0.7 cm of the HSDL-3211 to obtain optimum noise immunity.
