HSDL-3007
IrDA
Data Compliant Low Power 115.2 Kbit/s with Remote
Control Infrared Transceiver
Data Sheet
Description
The HSDL-3007 is a new generation ultra-low profile
enhanced infrared (IR) transceiver module that provides
the capability of (1) interface between logic and IR sig-
nals for through-air, serial, half-duplex IR data link, and
(2) IR remote control transmission for universal remote
control applications. The HSDL-3007 can be used for
IrDA as well as remote control application without the
need of any additional external components for multi-
plexing.
The HSDL-3007 is fully compliant to IrDA
Physical Layer
specification version 1.4 low power from 9.6 kbit/s to
115.2 kbit/s (SIR) and IEC825 Class 1 eye safety stan-
dards.
The HSDL-3007 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 1.8V. These features are ideal for
battery operated mobile devices such as PDAs and mo-
bile phones that require low power consumption

Notes:
1. At IrDA mode, it is a contant current source. At RC mode, the current can be controlled by external resistor, R1, which is tied to Vled. Refer to
the table below for recommended series resistor value.
2. Complete shutdown of IC and PIN diode. Do NOT float this pin.
3. This pin is used to transmit serial data when SD pin is low. If held high for longer than 50 µs, the LED is turned off. Do NOT float this pin.
4. 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.
5. Regulated, 2.4V to 3.6V
6. Logic high turns on the RC LED. If held high longer than 50 µs, the RC LED is turned off. Do NOT float the pin.
7. Connect to ASIC logic controller supply voltage or Vcc. The voltage at this pin should be equal to or less than Vcc.
8. Connect to system ground.
CAUTION: The BiCMOS inherent to the design of this component increases the component’s susceptibil-
ity to damage from electrostatic discharge (ESD). It is advised that normal static precautions be taken
in handling and assembly of this component to prevent damage and/or degradation which may be
induced by ESD
