ASDL-3023

ASDL-3023 IrDA Data Compliant Low Power 4Mbit/s with Remote Control Infrared Transceiver Data Sheet Description The ASDL-3023 is a new generation low profile high speed enhanced infrared (IR) transceiver module that provides the capability of (1) interface between logic and IR signals for through-air, serial, half-duplex IR data link, and (2) IR remote control transmission for universal remote control applications. The ASDL-3023 can be used for IrDA as well as remote control application without the need of any additional external components for multiplexing. The ASDL-3023 is fully compliant to IrDA Physical Layer specification version 1.4 low power from 9.6 kbit/s to 4.0 Mbit/s (FIR) and IEC825 Class 1 eye safety standards. The ASDL-3023 can be shutdown completely to achieve very low power consumption. In the shutdown mode, the PIN diode will be inactive and thus producing very little photocurrent even under very bright ambient light. It is also designed to interface to input/output logic circuits as low as 1.5V. These features are ideal for battery operated mobile devices such as PDAs and mobile phones that require low power consumption.

Refer to the table below for recommended series resistor value. 2. This pin is used to transmit serial data when SD pin is low. If held high for longer than 50 ms, the LED is turned off. Do NOT float this pin. 3. 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 4. Complete shutdown of IC and PIN diode. The pin is used for setting IR receiver bandwidth, range of IR LED current and RC drive programming mode. Refer to section on “Bandwidth Selection Timing” and “Remote Control Drive Modes” for more information. Do NOT float this pin. *** 5. Connect to ASIC logic controller supply voltage or Vcc. The voltage at this pin should be equal to or less than Vcc. 6. Logic high turns on the RC LED. If held high longer than 50 ms, the RC LED is turned off. Do NOT float the pin. 7.
