Note 2: Standard transmitter In the figure above, the transmitter output VOUT is 80m Vpp. The TPS703(F) in this application has a short−circuit current of Isc = 1.24μA when measured at E = 0.1mW/cm2. (E is the radiant incidence when a CIE standard light source A is used.) 20cm 10kΩ TPS703(F) VOUT 10kΩ Transmitter (TLN115A(F) is used.) f0 = 455kHz Duty = 50% +10V 10μF GND Note 3: Transmission range L Standard transmitter (TLN105B(F)) L L is the maximum distance at which burst waves can be received from the transmitter unit, and at which data can be processed by the receiver unit. Note that when signals other than the recommended burst wave are transmitted, the transmission range may be reduced or a malfunction may occur. (*) The TLN105B(F) is used as the standard LED transmitter. If the TLN231(F) is used instead, the transmission range is 1.2 times that of the TLN105B(F). Example: 6m (with TLN105B(F)) ⇒ 10.1m (with TLN231(F)) 2 2007-10-01 TPS830(F) Note 4: Burst wave 30μs 55μs Carrier frequency:fo = 455kHz Duty = 50% VCC VOH 2.5V VOL GND TON TOFF Note 5: Electromagnetic sensitivity TPS830(F) VP 50Ω d ES = VP/d (VP-P / m) Mount the device between two parallel boards separated by a distance of d. Apply voltages modulated using frequencies ranging from 10kHz to 50MHz across the boards and read off the voltage at which noise is generated in the output from the device.

GND Bit Pattern Designing Example (reference) • Example of code signal = 11010010 Sequence of LED signals = 1 must be avoided. If LED signals of 1 sequence, TPS830(F) may not receive LED signals properly. After an LED signal of 1, 0 must be sent (55μ or longer interval necessary). Please take this into account when designing a bit pattern. The following shows the bit pattern t example that is converted at first code signals to LED signals as shown on the right diagram. <Conversion example> Code signal LED signal 0 → 00 1 → 10 <Pattern example> LED signals 1 0 1 0 0 0 1 0 0 0 0 0 1 0 0 0 62μs 26μs Code signals 1 1 0 1 0 0 1 0 Precautions 1. 2. 3. 4. 5. 6. To stabilize the power line, insert a bypass capacitor of up to 0.01μF between VCC and GND, close to the device. At power−on the internal circuit takes about 100μs to stabilize. During this period the output signal is unstable and may change. To avoid unnecessary oscillation, insert a bypass capacitor of 1000pF between VCC and GND. When using the device, please take the device’s characteristics, the operating environment and the characteristics of pairing LED device into considerations. Soldering temperature: ≦ 260°C, soldering time : ≦ 5s (Soldering must be performed under the 2mm from the body of the device.) When forming the leads, bend each lead under the 2mm from the body of the device. Soldering must be performed after the leads have been formed. 4 2007-10-01 TPS830(F) ICC – Ta (typ.)
