HSDL-3020
IrDA
®
Data Compliant Low Power 4.0 Mbit/s
with Remote Control Infrared Transceiver
Data Sheet
Description
The HSDL-3020 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
operating at the optimum 940 nm wavelength for
universal remote control applications. The HSDL-3020
features an enhanced 3 lens optical package for
optimized IrDA and RC performance.
The module is fully compliant to IrDA® Physical Layer
specifi-cation version 1.4 low power from 9.6 kbit/s to
4.0 Mbit/s (FIR) and IEC825 Class 1 eye safety standards.
The HSDL-3020 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 1.5 V. These features are ideal for
battery operated mobile devices such as PDAs and
mobile phones that require low power consumption.

Notes:
1. Internally connected to RC LED driver. Leave this pin unconnected.
2. Tied through external resistor, R3, to RC Vled. Refer to the table below for recommended series resistor value.
3. Tied through external resistor, R2, to IR Vled. Refer to the table below for recommended series resistor value.
4. Connect to ASIC logic controller supply voltage or V
CC
. The voltage at this pin should be equal to or less than V
CC
.
5. 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.
6. 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.
7. Complete shutdown of IC and PIN diode. The pin is used for setting receiver bandwidth 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.
8. Regulated, 2.4 V to 3.6 V.
9. Logic high turns on the RC LED. If held high longer than 50
µs,
the RC LED is turned off. Do NOT float this pin.
10. Connect to system ground.
11, Connect to system ground via a low inductance trace. For best performance, do not connect directly to the transceiver GND pin.
CAUTIONS:
The BiCMOS inherent to the design of this component increases the component’s
susceptibility 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.
