Remote Control Receiver Module 1. Basic Knowledge of Remote Control 2 1) Remote Control Receiver Module 1) The Remote Control Receiver Module is an optical communications module that uses infrared rays for TV sets and audio equipment. Conventional models were of cubic structure (1.5 × 1.5cm) incorporating a PCB mounted with a PIN photodiode, receiver IC, and capacitors and covered with a shield casing. Since ROHM released a one-package model, however, mold resin models of one-package structure have been mainstream products. ROHM provides the RPM7100-Hx Series 120 RPM7200-Hx Series (operating at 5V) and the RPM7200-Hx Series (operating at 3.0V). Both of them are of two-chip e (%) 100 Competitors' C c 5-V products structure incorporating a PIN photodiode and an 80 st receiver IC.

Infrared rays are invisible and longer in wavelength than visible light. Remote control models use a dominant wavelength around 950nm. 3) Reason for Use of Infrared Rays The remote control is overwhelmingly used indoors under light emitted from lighting apparatus, which includes quantities of visible light components. In order to prevent such light from becoming a noise source, the remote control uses infrared rays, which is rarely included in the light emitted 100 from the lighting apparatus. 80 In other words, the remote control uses infrared y (%) rays in order to improve the signal-to-noise ratio. sitivit 60 n e The RPM7100-Hx Series and RPM7200-Hx e s 40 v Series eliminate optical noise by providing the elati R 20 resin packages with a filter function that shuts off visible light. 0 40050060070080090010001100 Wavelength: λ (nm) Fig. 2 Relative Sensitivity of RPM7100-Hx/RPM7200-Hx 9

The same PPM (pulse position modulation) code is used to discriminate 1 and 0 according to the pulse time interval. The amplitude of the subcarrier is modified according to the pulse train. Therefore, the subcarrier frequency range is between 33 and 57kHz. 13

The trailer is used to discriminate the completion of t ransmission. With the diffusion of infrared remote control systems for home appliances, certain standards apply to each manufacturer's signal transmission method in the AEHA's format with the method officially registered, thus preventing the remote control and controlled equipment from he m alfunctioning. The transmission format presently in use takes individual measures for the prevention of se malfunctions. For example, a method is used to transmit the data code three times and read the data code only when the leader code is received correctly at least twice in the three ier transmissions. Another method is also used to transmit front and back signals and judge the data only after the front and back signals coincide. 14

Remote Control Receiver Module 6. Precautions for Designing Receiver Side 1) Design of Beam Spread Angle • V • Installation of Sensor Window and Remote Control Receiver Module If the specified beam spread angle is θ1, design the sensor window to satisfy the following condition, as shown in the figure on the right-hand side: θ>θ1. If the angle is specified from the lens top, there will be no optical signal incidence at the edge of the lens. Therefore, the Remote Control Receiver Module will not fully demonstrate its performance. Remote Control Design the window at the angle Receiver Module connecting the lens edge and window edge. Fig. 18 Sensor Window of RPM7100-Hx/RPM7200-Hx • Light Guide Tube Apply the condition below, on the condition that the diameter of light guide tube on the Remote Control Receiver Module is φ1 and that of the lens of the Remote Control φ1 Receiver is φ2. φ1>φ2 The maximum sensitivity is obtained by Remote Control beaming the optical signal at the whole Receiver Module φ2 surface of the lens. Fig. 19 Light Guide Tube of RPM7100-Hx/RPM7200-Hx 2) Environment-resistive Noise Design Environments where the Remote Control Receiver Module is used have quantities of noise • sources. The Remote Control Receiver Module has very high sensitivity to receive minute optical signals. Therefore, the Remote Control Receiver Module takes a variety of countermeasures against each noise source. If there is an interference of excessive noise, however, the Remote Control Receiver Module may malfunction. 17

It depends on the goverment policy. Although the light emission frequency is sufficiently lower than the subcarrier frequency of the remote control, the harmonics may cause on a malfunction (i.e., a reduction in the effective distance may result). he nd High Frequency Modulation Type Fluorescent Lamp ol In order to reduce the flickering of light, the light emission frequency of an inverter fluorescent lamp is modified. The frequency is around 45kHz, which is close to the subcarrier of the remote controller and becomes noise that cannot be eliminated with ease. by With the incidence of inverter fluorescent light, the effective distance will be shorter in le comparison with the case of the rapid fluorescent lamp. Incandescent Lamp and Sunlight These light sources have DC noise but including a large quantity of infrared components used for the remote control. The incidence of the noise results in a reduction in effective distance. se • Countermeasures of Set for Optical Noise ute of Lighting apparatus becomes an optical noise source. In many cases, this noise source is se, radiated from the upper side. Therefore, at the time of designing the window of the set, limit the incidence of light from the upper side. 18

Remote Control Receiver Module • Other Noise Sources • H Power Supply Noise Power supply noise may wrap around from the digital block of the set or may result due to the insufficient smoothing of the power supply circuit. If there are power supply ripples, the effective distance may be reduced. The RPM7100-Hx and RPM7200-Hx Series are designed to reduce the droppage of effective distance to the minimum. Electromagnetic Noise The following ones may be sources of electromagnetic noise. • CRT noise • LCD (driver) noise (i.e., horizontal synchronizing signal at 38kHz) • Fluorescent lamp • Noise radiated from power supply circuit 3) Grounding and Pattern Designing • V • Output pull-up resistance «Circuit diagram» R C + Vcc 47µF ROUT Microcontroller GND Fig. 21 Pull-up Circuit Diagram The pull-up resistance connected to the output must limit the absorption current of Remote Control Receiving Module to a range not exceeding a specified value, or otherwise the low-level voltage will be in excess of the specified value.

Fig. 22 Shield • Vcc and Ground Pattern Designing The Remote Control Receiver Module is highly sensitive in order to receive an infrared signal that is far away. Although a sufficient countermeasure against power ripples is taken, the user should take a further countermeasure in preparation for unforeseen malfunctions. «Good example» Noise Noise is reduced as Noise much as possible within the digital block loop. There is little influence because the common impedance is low. Increase the occupied ground area to lower the common VDD VVCCCC impedance.

In order to correct the errors, T1" and T2" are provided with margins according to the software discrimination of receiving, thus making it possible to increase the effective distance. 21

Distance 8. Measures for Preventing Malfunctions If there is strong external noise (e.g., optical noise, electromagnetic noise, or power supply ripples), noise pulses may be generated from the output terminal regardless of whether the input signal exists or not. 1) Receiving Code Discrimination By always discriminating the receiving of a number of bits in combination as a code, the malfunctioning of the unit can be prevented. In the above case, it is ideal to use the lead pulse and the code. he he 2) Falling Edge Discrimination of Single Pulse ns he Noise pulses may be generated in the output due to the influence of external noise. Therefore, the discrimination of receiving with a non-coded signal (e.g., the falling edge of a single pulse only) is not recommendable. 22

Receiving Receiving is OK Noise pulse The noise cannot be discriminated from the signal. Fig. 27 Single Transmission Pulse 3) Subcarrier • Coincidence of Subcarrier Make sure that the subcarrier coincides with the center frequency of the Remote Control Receiver Module, or otherwise the effective distance may be shorter or the Remote Control Receiver Module may fail to receive the signal. • Constant Duty of Subcarrier Make sure that the duty of the subcarrier is constant. The discontinuance of the duty may cause a receiving output pulse split and result in a receiving error.
