Notes:
1. C1,C2, and C3 must be placed within 0.7 cm of the HSDL-3202 to obtain optimum noise immunity. If V
2. If TXD is stuck in the high state, the LED will turn off after about 20 s.
3. In-Band IrDA signals and data rates
4. RXD Logic Low is a pulsed response. The condition is maintained for a duration that is dependent upon the data pattern.
5. RXD Logic High during shutdown is a weak pullup resistor (300 k ).
6. An in-band optical signal is a pulse/sequence where the peak wavelength,
7. For in-band signals [115.2 Kb/s where 8.1 W/cm
8. Latency is defined as the time from the last TXD light output pulse until the receiver has recovered full sensitivity.
9. Receiver wake up time is measured from the SD pin high-to-low transition or V
10. Transmitter wake up time is measured from the SD pin high-to-low transition or V
11. Typical values are at EI = 10 mW/cm
12. Maximum value is at EI = 500 mW/cm
