| TSOP7000 Vishay Telefunken IR Receiver for High Data Rate PCM at 455kHz Description The TSOP7000 is a miniaturized receiver for infrared remote control and IR data transmission. PIN diode and preamplifier are assembled on lead frame, the epoxy package is designed as IR filter. The demodulated output signal can directly be decoded by a microprocessor. The main benefit is the operation with high data rates and long distances. 14 500 Features D Photo detector and preamplifier in one package D Internal Bandfilter for PCM frequency D Internal shielding against electrical field disturbance Special Features D D D D D D Data rate 20 kbit/s Small size package Supply voltage 2.7 - 5.5V Short settling time after power on High envelope duty cycle can be received Enhanced immunity against disturbance from energy saving lamps D TTL and CMOS compatibility D Output active low Block Diagram 3 Input Control Circuit VS 10 kW 1 OUT PIN AGC Band Pass Demodulator 2 16499 GND Document Number 82147 Rev. 3, 13-Mar-01 www.vishay.com 1 (7) TSOP7000 Vishay Telefunken Absolute Maximum Ratings Tamb = 25_C Parameter Supply Voltage Voltage at output to supply Supply Current Output Voltage Output Current Junction Temperature Storage Temperature Range Operating Temperature Range Soldering Temperature Power Consumption Test Conditions Pin 3 Pin 1 Pin 3 Pin 1 Pin 1 Symbol VS VS - VO IS VO IO C Tstg Tamb Tsd Ptot Value -0.3...6.0 -0.3...VS+0.3 5 -0.3...6.0 15 100 -25...+85 -25...+85 260 30 Unit V V mA V mA C C C C mW t x 10 s, 1 mm from case Basic Characteristics Tamb = 25_C, VS = 5.0V Parameter Supply Current (Pin 3) Supply Voltage (Pin 3) Transmission Distance Test Conditions Dark ambient Ev = 40 klx, sunlight Symbol ISD ISH VS dmax dmax Ee min Ee max VQL VQH Q Optical test signal of Fig.1, 1.5mW/m2 Ee 30W/m2 Optical test signal of Fig.1, Ee > 1.5mW/m2 Valid data after power on Leading edge of output pulse No external pull up resistor 1kW external pull up resistor Angle of half transmission distance 30 100 VS - 0.25 10 -15 15 50 0.4 12 1.2 45 +5 +15 36 Min Typ 2.0 2.3 5 20 12 0.8 1.5 Max 2.7 5.5 Unit mA mA V m m mW/m2 W/m2 mV V lp= 870nm, IR Diode TSHF5400, IF = 300 mA lp= 950nm, IR Diode TSAL6400, IF = 300 mA lp = 870nm, optical test signal of Fig.1 Optical test signal of Fig.1 1kW external pull up resistor No external pull-up resistor 2.7 Threshold Irradiance Maximum Irradiance Output Voltage Low (Pin 1) Output Voltage High (Pin 1) Bandpassfilter quality Out-Pulse width tolerance Delay time of output pulse Receiver start up time Falling time Rise time Directivity Dtpo tdon tV tf tr tr 1/2 ms ms ms ms ms ms deg www.vishay.com 2 (7) Document Number 82147 Rev. 3, 13-Mar-01 TSOP7000 Vishay Telefunken Optical Test Signal (f=455kHz, 10cycles/burst) Ee tpi = 22 s 2.2 s > 48.6 s (min. duty cycle) t 16792 Output Signal of TSOP7000 VQ VQH 50% VQL tpo = tpi 15 s tf tr tdon tpo 90% 10% t Figure 1.

A bandpassfilter, an automatic gain control and an integrator stage is used to suppress such disturbances. The distinguishing marks between data signal and disturbance are carrier frequency, burst length and the envelope duty cycle. The data signal should fullfill the following conditions: D D D D D The carrier frequency should be close to 455kHz. The burstlength should be at least 22ms (10 cycles of the carrier signal) and shorter than 500ms. The separation time between two consecutive bursts should be at least 26ms. If the data bursts are longer than 500ms then the envelope duty cycle is limited to 25%. The duty cycle of the carrier signal (455kHz) may be between 50% (1.1ms pulses) and 10% (0.2.s pulses). The longer duty cycle may help to save battery power.

Meet all present and future national and international statutory requirements. 2. Regularly and continuously improve the performance of our products, processes, distribution and operating systems with respect to their impact on the health and safety of our employees and the public, as well as their impact on the environment. It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as ozone depleting substances ( ODSs ). The Montreal Protocol ( 1987 ) and its London Amendments ( 1990 ) intend to severely restrict the use of ODSs and forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier ban on these substances. Vishay Semiconductor GmbH has been able to use its policy of continuous improvements to eliminate the use of ODSs listed in the following documents. 1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively 2 . Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental Protection Agency ( EPA ) in the USA 3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C ( transitional substances ) respectively. Vishay Semiconductor GmbH can certify that our semiconductors are not manufactured with ozone depleting substances and do not contain such substances. We reserve the right to make changes to improve technical design and may do so without further notice. Parameters can vary in different applications. All operating parameters must be validated for each customer application by the customer. Should the buyer use Vishay-Telefunken products for any unintended or unauthorized application, the buyer shall indemnify Vishay-Telefunken against all claims, costs, damages, and expenses, arising out of, directly or indirectly, any claim of personal damage, injury or death associated with such unintended or unauthorized use.
