Units Conditions Note Transceiver SD Logic High VIH 2/3 IOVCC – IOVCC V IOVCC ≥ 1.8 V Levels Low VIL 0 – 1/3 IOVCC V IOVCC ≥ 1.8 V SD Input High IH – 10 200 nA VI ≥ 2/3 IOVCC. Max value at 25°C Current Low IL –300 –10 – nA 0 ≤ VI ≤ 1/3 IOVCC. Max value at 25°C Supply Shutdown ICC1 – 10 200 nA VCC = 3.6 V, VSD = IOVCC Current Idle ICC2 – 100 250 µAVCC = 3.6 V, VI(TXD) ≤ 1/3 IOVCC, EI=0 Peak ICC3 – 2.0 10.0 mA VCC = 3.6 V, VI(TXD) ≤ 1/3 IOVCC 11, 12 Active Receive Peak ICC4 – 5.0 9.0 mA VCC = 3.6 V, VI(TXD) ≤ 2/3 IOVCC 11 Active Transmit IOVCC Current IIOVCC – 30 200 nA Notes: 1. C1,C2, and C3 must be placed within 0.7 cm of the HSDL-3202 to obtain optimum noise immunity. If VLED and VCC are tied together, then the application may use one less capacitor. 2. If TXD is stuck in the high state, the LED will turn off after about 20 µs. 3. In-Band IrDA signals and data rates ≤ 115.2 Kb/s. 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 Ω). 6. An in-band optical signal is a pulse/sequence where the peak wavelength, λp, is defined as 850 nm ≤ λp ≤ 900 nm, and the pulse characteristics are compliant with the IrDA Serial Infrared Physical Layer Link Specification. 7. For in-band signals [115.2 Kb/s where 8.1 µW/cm2 ≤ EI ≤ 500 mW/cm2]. 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 VCC power on to valid RXD output. 10. Transmitter wake up time is measured from the SD pin high-to-low transition or VCC power on to valid light output in response to a TXD pulse. 11. Typical values are at EI = 10 mW/cm2. 12. Maximum value is at EI = 500 mW/cm2. |
