RY5HD01  
Technical Information  
Infrared Transceiver Module  
FEATURES  
• Fully Compliant to IrDA1.1 - 4 Mbps  
• 3.3 V Low Voltage Operation  
• Compatible with the Legacy IrDA (IrDA1) and  
SHARP ASK  
• Backward Compatible with Slower Speeds  
• Excellent Noise Immunity  
• Single RX Output for Multiple Infrared Port Design  
• Optimized Interface to Sharp UIRCC Modem ASIC  
• Supported by All Interface Chips  
RY5HD01-1  
Figure 1. RY5HD01  
DESCRIPTION  
The Sharp RY5HD01, a 3.3 V low voltage operating  
infrared transceiver module, provides the interface  
between logic and IR signals for through-air, serial,  
half-duplex IR wireless data links and is designed to  
satisfy the IrDA physical layer specifications.  
PD  
LED  
COMPARATOR  
The Sharp RY5HD01 contains a high speed, high  
efficiency, low power consumption AlGaAs LED, a sili-  
con PIN photodiode, and the low power driven new  
bipolar integrated circuit. The IC contains a LED driver  
circuit and a receiver, that provides single RX out sup-  
porting both 9.6 to 115.2 kbps IrDA 1.0 signals, and  
1M/4 Mbps IrDA1.1 signals. This single RX output  
design provides manufacturers with multiple infrared  
port capability in one application, wherever the infrared  
port is desired to be located.

Though the RY5HD01 transceiver module is oper-  
ated at 3.3 V, the module can still work at 5.0 V without  
any performance desiccation. The manufacturers  
surely would get the advantage of an energy saving  
design in any application field, while having alterna-  
tives for other components.

APPLYING POWER SAVING CIRCUITRY  
TO RY5HD01  
Though the Sharp RY5HD01 IR transceiver module  
is designed to be operated at 3.3 V, power saving cir-  
cuit may be required depending on the applications.  
By applying the circuit (marked by dot lines), the IR  
port can be managed manually to shut-down the func-  
tion and save the battery powers.

Technical Information  
Infrared Transceiver Module  
RY5HD01  
The noises may be observed on the pinouts  
because of the noises through the receiver and the  
emitter windows, although the metal shield blocks the  
electromagnetic/electrostatic noise from inside and  
outside of the unit. Possible noise sources are DC/DC  
converters and the LCD backlight supply. Please keep  
the transceiver module mounted apart from such noise  
sources.  
PRECAUTION ON USE  
If the surface of the IRLED and PD are dirty or dusty,  
communication capabilities may be effected. In such  
cases, wipe them gently with a soft cloth and avoid  
scratching the surfaces. If solvent is required, use  
methyl alcohol or ethyl alcohol, and be careful not to let  
the solvent seep inside of the transceiver module.  
Please also note that the lot numbers are stamped on  
the backside of the transceiver modules.  
The IR transceiver modules do not transfer signals  
with 100% accuracy due to the effect of ambient light.  
These IR transceiver modules are intended to be used  
in the consumer electronics for home use in principle,  
and must not be used for applications such as power  
control, security, medical equipment, and others that  
may have a threat to personal safety.  
Avoid using the transceiver modules under the dew  
condensed conditions.  
If the electronic noise of the power supply is large,  
attach an external low pass filter close to the trans-  
ceiver module pinout. The electronic noise of the power  
supply is particularly concerned in the IrDA-SIR com-  
munication mode.

LIFE SUPPORT POLICY  
SHARP components should not be used in medical devices with life support functions or in safety equipment (or similiar applications where  
component failure would result in loss of life or physical harm) without the written approval of an officer of the SHARP Corporation.  
LIMITED WARRANTY  
SHARP warrants to its Customer that the Products will be free from defects in material and workmanship under normal use and service for a  
period of one year from the date of invoice. Customer's exclusive remedy for breach of this warranty is that SHARP will either (i) repair or  
replace, at its option, any Product which fails during the warranty period because of such defect (if Customer promptly reported the failure to  
SHARP in writing) or, (ii) if SHARP is unable to repair or replace, refund the purchase price of the Product upon its return to SHARP. This  
warranty does not apply to any Product which has been subjected to misuse, abnormal service or handling, or which has been altered or  
modified in design or construction, or which has been serviced or repaired by anyone other than Sharp. The warranties set forth herein are in  
lieu of, and exclusive of, all other warranties, express or implied. ALL EXPRESS AND IMPLIED WARRANTIES, INCLUDING THE  
WARRANTIES OF MERCHANTABILITY, FITNESS FOR USE AND FITNESS FOR A PARTICULAR PURPOSE, ARE SPECIFICALLY  
EXCLUDED. In no event will Sharp be liable, or in any way responsible, for any incidental or consequential economic or property damage.  
The above warranty is also extended to Customers of Sharp authorized distributors with the following exception: reports of failures of Products  
during the warranty period and return of Products that were purchased from an authorized distributor must be made through the distributor.  
In case Sharp is unable to repair or replace such Products, refunds will be issued to the distributor in the amount of distributor cost.  
SHARP reserves the right to make changes in specifications at any time and without notice. SHARP does not assume any responsibility  
for the use of any circuitry described; no circuit patent licenses are implied.
