Notes:
1. CX1 must be placed within 0.7 cm of HSDL-3003 to obtain optimum noise immunity.
2. The supply rejection performance can be enhanced by including CX2, as shown in Figure 1, in
environment with noisy power supplies.

Output is at LOW pulse response when light pulse is seen
Tie this pin to system ground
Tied through external resistor, R1, to VLED from 2.4 to 4.5 Volt
No Connection
Logic high turns on the IrDA LED. If held HIGH longer than
~50 s, the IrDA LED is turned off. TxD_IrDA must be driven either
HIGH or LOW. Do not leave the pin floating
Complete shutdown TxD_IrDA, RxD_IrDA, and PIN diode. Do not
leave the pin floating
Regulated, 2.4 to 3.6 Volt
Logic high turns on the RC LED. If held HIGH longer than ~50 s,
Tie to system ground via a low inductance trace. For best
performance, do not tie it to the HSDL-3003 GND pin directly
the RC LED is turned off. TxD_RC must be driven either HIGH or
LOW. Do not leave the pin floating
