IR Receiver Modules for Remote Control Systems

Description

The TSOP348..VI1 - series are miniaturized receivers

for infrared remote control systems. 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. TSOP348..VI1 is the

standard IR remote control receiver series for 3 V

supply voltage, supporting all major transmission

codes.

Suitable Data Format

16920

Time ( ms )

The circuit of the TSOP348..VI1 is designed in that

way that unexpected output pulses due to noise or

disturbance signals are avoided. A bandpass filter, an

integrator stage and an automatic gain control are

used to suppress such disturbances.

Figure 14. IR Signal from Fluorescent Lamp with low Modulation

The distinguishing mark between data signal and dis-

turbance signal are carrier frequency, burst length

and duty cycle.

IR Signal from fluorescent

lamp with high modulation

The data signal should fulfill the following conditions:

• Carrier frequency should be close to center fre-

quency of the bandpass (e.g. 38 kHz).

• Burst length should be 10 cycles/burst or longer.

• After each burst which is between 10 cycles and 70

cycles a gap time of at least 14 cycles is necessary.

• For each burst which is longer than 1.8 ms a corre-

sponding gap time is necessary at some time in the

data stream. This gap time should be at least 4 times

longer than the burst.

16921

Time ( ms )

Figure 15. IR Signal from Fluorescent Lamp with high Modulation

• Up to 800 short bursts per second can be received

continuously.

Some examples for suitable data format are: NEC

Code (repetitive pulse), NEC Code (repetitive data),

Toshiba Micom Format, Sharp Code, RC5 Code,

RC6 Code, R-2000 Code, Sony Code.

When a disturbance signal is applied to the

TSOP348..VI1 it can still receive the data signal.

However the sensitivity is reduced to that level that no

unexpected pulses will occur.

Some examples for such disturbance signals which

are suppressed by the TSOP348..VI1 are:

• DC light (e.g. from tungsten bulb or sunlight)

Ozone Depleting Substances Policy Statement

It is the policy of Vishay Semiconductor GmbH to

1. Meet all present and future national and international statutory requirements.

2. Regularly and continuously improve the performance of our products, processes, distribution and

operatingsystems 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 Semiconductors products for any

unintended or unauthorized application, the buyer shall indemnify Vishay Semiconductors 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.
